Warning level raised on another Japanese volcano a week after fatal eruption

TOKYO (Reuters) - Japan raised the warning level on another volcano on Tuesday, exactly a week after an dramatic eruption at another peak killed one man, injured nearly a dozen others and stranded scores of skiers - including foreign tourists - for several hours.

Japan’s Meteorological Agency lifted the warning on Zao, a cluster of volcanoes in northern Japan whose highest point is 1,841 meters (6,040 ft), to 2 from 1, meaning that people should avoid going near the crater.

“There is a possibility of a small-scale eruption,” the agency said in a statement, noting that a number of small earth movements were detected on Tuesday, along with a slight bulging of the ground in one area.

It also warned of the possibility that volcanic rocks could be thrown as far as 1.2 km in any eruption.

The announcement came a week after a member of Japan’s military was struck and killed when rocks from the sudden eruption of the Kusatsu-Shirane volcano rained down on skiers at a mountain resort in central Japan.

Video footage taken by skiers on the mountain, including some from Taiwan, showed black ash boiling up into the sky as stones plummeted down, some punching holes in the metal roof of a ski gondola. Eleven people were injured and around 100 skiers took refuge in a mountain hut for several hours until rescued.

Zao, like Kusatsu-Shirane, is a popular resort area famed for its “snow monsters,” created by water vapor freezing on trees in winter. Its slopes are packed with skiers in winter and hikers in other seasons.

Japan has 110 active volcanoes and monitors 47 of them around the clock. In September 2014, 63 people were killed on Mount Ontake, the worst volcanic disaster in Japan for nearly 90 years.

Alertlevel Vanuatu volcano raised
The Vanuatu Meteorology and Geohazards Department (VMGD) raised the Volcanic Alert Level of Gaua volcano from Level 1 to Level 2 on January 31, 2018. The decision restricts visitors from approaching the volcanic cone. A long period of dormancy of this volcano ended in 1962 with an eruption on its SE flank. Since then, the volcano erupted 15 times, including its last eruption in 2011.

Observations performed from December 2017 to January 2018 confirm that the activity at Gaua volcano consists of ongoing volcanic steam cloud which may content volcanic gases, VGMD said today. These observations and seismic analysis confirm that the volcano activity has increased to the major unrest state.

Alert Level for Gaua volcano was at Level 1 since December 21, 2010. Based on its slight increased seismic activity and observation of ongoing volcanic gas emission and steam plumes in December 2017 and January 2018, the Volcanic Alert Level (VAL) was raised to Level 2. The current observations are consistent with the Alert Level 2 activity which indicates 'Major Unrest' - the danger is around the crater rim and specific area, there is a considerable possibility of an eruption and also a chance of a flank eruption.

VMGD advises all tourism agencies, local authorities, people of Gaua and the general public not to access Gaua's volcanic cone. In this area, volcanic gases will always be expected and other volcanic risks could occur at any time in such major unrest state. In addition, visitors approaching the volcano may smell volcanic gases.

Gaua Island is actually the exposed upper cone and summit of a stratovolcano that is 3 000 meters (10 000 feet) high and 40 kilometers (25 miles) wide. Most of the volcano is submerged beneath the Pacific Ocean.

Fuego eruption
Guatemalan authorities issued an Orange Alert for Fuego volcano after its first eruption of the year on February 1, 2018. Explosions at the volcano lasted 20 hours, generating pyroclastic flows and a column of ash up to 6 500 m (21 325 feet) above sea level. Ash drifted up to 40 km (25 miles) to the west and southwest.

CONRED said the eruption affected 47 704 people in the departments of Sacatepéquez, Chimaltenango, Escuintla and Suchitepéquez.

Pyroclastic flows descended through the Honda, Santa Teresa, Las Lajas and Ceniza ravines with lengths between 700 and 1 500 meters (2 300 - 4 900 feet), INSIVUMEH reported.

Ashfall was recorded in the La Rochela and Ceylon communities in Escuintla, Escuintla; in the urban centers of Santa Lucia Cotzumalguapa and Siquinalá, Escuintla; San Pedro Yepocapa, Palo Verde Estate, Sangre de Cristo, Panimaché I and II, Santa Sofía, Morales and Yucales, in Yepocapa, Chimaltenango.

In addition, authorities closed the National Route 14 at kilometer 90 due to the advance of pyroclastic flows. The closure was a preventive measure.

Due to the increase in activity and the presence of ash, the education authorities of Sacatepéquez and Escuintla suspended all educational activities.

To provide a better response and coordination in the municipality, San Juan Alotenango, Sacatepéquez, declared Municipal Red Alert and activated the Municipal Emergency Operations Center, which identifies the places that could function as shelters.

The population living in the vicinity of the volcano is urged to comply with instructions issued by authorities and stay away from the ravines or places that could be affected by ballistic materials expelled from the crater.

In addition, precautionary measures must also be taken for ashfall, protecting the containers where water for human consumption is stored, covering eyes and respiratory passages in the presence of fine ash particles and reporting observed incidents at number 119 of the CONRED.

A high impact volcanic ash eruption started at Sinabung volcano, Indonesia at 01:53 UTC on Monday, February 19, 2018. Pyroclastic flows traveled 3.5 km (2.1 miles) and 4.9 km (3 miles) from the summit. Ash plume was reaching an altitude of 16.7 km (55 000 feet) above sea level, the Darwin VAAC reported 04:50 UTC. Aviation Color Code was raised from Orange to Red.

The eruption started at 01:53 UTC (08:53 local time) and lasted 4 minutes and 51 seconds, Sinabung Volcano Observatory reported.

Their best estimate of the ash cloud top at 02:13 UTC was 7.4 km (23 872 feet) above sea level. The observatory noted that the ash cloud is drifting to the east and southeast, adding that its top may be higher than what can be clearly observed from the ground. The Aviation Color Code was raised from Orange to Red.

"Pyroclastic flow is observed through the ESE slope to a distance of 3.5 km [2.1 miles] from the summit and through the south slope to a distance of 4.9 km [3 miles] from the summit," they said.

Major ashfall was reported around the volcano and visibility was down to only 5 to 10 meters (16 - 32 feet).

The volcanic ash cloud is reaching an altitude of 16.7 km (55 000 feet) above sea level and extending 46.3 km (28.7 miles) ENE, the Darwin VAAC reported 03:35 UTC. At the same time, the second volcanic ash cloud was reaching 7.6 km (25 000 feet) a.s.l. and extending 18.5 km (11.5 miles) S.

At 04:53 UTC, the Darwin VAAC said that one volcanic ash cloud was observed reaching an altitude of 13.7 km (45 000 feet) at 04:50 UTC and extending 138.9 km (86.3 miles) to the northwest, while the second volcanic ash cloud was reaching 6.7 km (22 000 feet) and extending 46.3 km (28.7 miles) to the south.

"High impact volcanic eruption is clearly observed on satellite imagery," they noted, adding that the 04:50 UTC volcanic ash cloud heights were estimated based on plume top IR temperature and 00:00 UTC February 19 Medan sounding.

Mount Shinmoe erupted explosive for first time in 7 years
Mount Shinmoe, a volcano in southwestern Japan, has erupted explosively for the first time in 7 years. Japan's Meteorological Agency is warning people not to go near the mountain.

The first eruption took place around 2:30 PM on Tuesday. Smoke spewed up 2,100 meters from the mountain's crater, and air vibrations from the volcanic activity were observed.

Twenty minutes later, after more explosive eruptions, smoke reached a height of 2,300 meters.

The mountain in the Kirishima range straddles Kagoshima and Miyazaki prefectures. Minor eruptions had been occurring at the volcano since Thursday.

Shinmoe last erupted explosively in March 2011.

The agency is keeping its alert level at 3 on a scale up to 5. It's warning of flying volcanic rocks within roughly 3 kilometers of the crater and pyroclastic flows, or fast currents of hot ash and rocks, within 2 kilometers.

It's also telling people downwind to exercise caution against volcanic gas and falling ash and small rocks, and saying windows could be shattered by air vibrations.

Etna volcano update: Earthquake swarms under eastern and western flanks

The volcano is becoming increasingly restless. Two earthquake swarms have occurred during the past days:

The first was at medium depths (mostly 10-30 km) beneath the eastern flank during 24-26 May, the second one started yesterday and is still continuing under the western flank at depths around 5-10 km. Both could indicate an intrusion of magma, and tremor levels are slightly elevated. Whether this heralds a new eruption in the near future (days, weeks?) is matter of speculation. So far, the quakes have been relatively weak.

When we visited Bocca Nuova last Saturday, we noticed relatively strong, pulsating gas emissions from not-very-deep seated explosions inside the main western vent. According to the mountain guides, this activity had increased, as well as degassing from some areas at the southern rim of the central crater as well as the NE crater

In Guatemala zijn zeker zeven mensen om het leven gekomen bij een vulkaanuitbarsting. Tientallen mensen raakten gewond.

De vulkaan Fuego, zo'n veertig kilometer ten zuidwesten van Guatemala-Stad, spuwt lava en hete as uit. Een lavastroom is het dorpje Rodeo binnengestroomd. "De stroom trad buiten zijn oevers en liep het dorpje in. Er zijn daar gewonde, verbrande en dode mensen", zei het hoofd van de hulpdiensten op de Guatemalteekse radio.

Vier mensen kwamen om het leven toen een huis vlam vatte door de hitte van de lavastroom. Twee kinderen verbrandden toen ze de uitbarsting bekeken vanaf een brug. Een slachtoffer werd gevonden door brandweerlieden en overleed later in de ambulance.

Elevated earthquake activity at Alaskan volcano
Seismicity at Alaska's Great Sitkin volcano has been at elevated levels over the past couple of days, followed by a signal that may represent a short-lived steam explosion on June 11. The last known eruption of this stratovolcano took place in 1974.

Seismicity at Great Sitkin volcano was at elevated levels over the past 5 days, the Alaska Volcano Observatory (AVO) reported 21:26 UTC on June 11, 2018.

This activity was followed by a signal at 19:39 UTC that may represent a short-lived steam explosion detected by seismic data.

AVO has thus raised the Aviation Color Code to Yellow and Alert Level to Advisory.

The last time the observatory raised Aviation Color Code to Yellow and Volcano Alert to Advisory was on November 22, 2017. The status was unchanged until January 18 of this year.

On November 19, 2017, local observers photographed a light-colored vapor plume rising about 300 m (984 feet) above the vent and drifting 15 - 20 km (9 - 12 miles) S. A satellite image acquired on November 21 showed steam continuously jetting from a small fumarole on the W side of the 1974 lava flow within the summit crater, and at least one area where snow and ice had been melted.

Seismicity at this volcano had fluctuated but increased overall since July 2016, most notably in June 2017. The seismic activity was characterized by earthquakes less than M 1, and occurred either just below the summit or just offshore the NW coast of the island, 30 km (18.6 miles) below sea level. Possible explosion signals were recorded in seismic data on January 10 and July 21, 2017, but there were no confirmed emissions.

The last known eruptive episode of this volcano took place from February 19, 1974 to September 16, 1974 (+/- 15 days) (VEI2).

Great Sitkin forms much of the northern side of Great Sitkin Island. A younger parasitic volcano capped by a small, 0.8 x 1.2 km (0.5 - 0.7 miles) ice-filled summit caldera was constructed within a large late-Pleistocene or early Holocene scarp formed by massive edifice failure that truncated an ancestral volcano and produced a submarine debris avalanche. Deposits from this and an older debris avalanche from a source to the south cover a broad area of the ocean floor north of the volcano. The summit lies along the eastern rim of the younger collapse scarp.

Deposits from an earlier caldera-forming eruption of unknown age cover the flanks of the island to a depth up to 6 m (20 feet). The small younger caldera was partially filled by lava domes emplaced in 1945 and 1974, and five small older flank lava domes, two of which lie on the coastline, were constructed along the northwest- and NNW-trending lines.

Hot springs, mud pots, and fumaroles occur near the head of Big Fox Creek, south of the volcano.

Historical eruptions have been recorded since the late-19th century.

The volcano is monitored by a five-station seismic network on Great Sitkin Island and with additional seismic stations on the nearby islands of Igitkin, Adak, Kagalaska, and Kanaga. A six-element infrasound array to detect explosions (atmospheric pressure waves) was installed on Adak Island in June 2017, although it is currently (June 2018) only partly operational. AVO also uses satellite imagery to monitor Great Sitkin Volcano.

Eartquake swarm detected under Colombian volcano
Colombian authorities are reporting significantly increased seismic activity under Galeras volcano, one of Colombia's most frequently active volcanos. Increased seismicity was first recorded on May 29 and June 2, 2018. The last eruption of this volcano took place in 2014 (VEI 2).

Earthquakes are located between 1 and 8 km (0.6 - 5 miles) to the northeast of the volcano at depths between 1.2 and 7.5 km (0.7 and 6 miles) from the top of the volcano (4 200 m / 12 800 feet a.s.l.), the Colombian Geological Service (SGC) reported in a special bulletin published 04:35 UTC today.

A total of 310 earthquakes have been reported between 09:35 UTC on June 12 when a M4.5 volcano-tectonic earthquake was recorded and 04:35 UTC today. Other geophysical and geochemical monitoring parameters have no significant changes.

Some of the quakes were felt by nearby residents, according to the preliminary reports of the Office of Disaster Risk Management of the Municipality of Pasto.

The quakes produced several landslides in the municipality of Narino, affecting homes in the northern parts of the city of San Juan de Pasto.

The Alert Level remains at III (Yellow; "changes in the behavior of volcanic activity") since 2011.

SGC urged residents to only heed information from official sources, adding that someone is spreading false information about the activity status of the volcano through social media. This false information is designed to generate panic and confusion in nearby communities, SGC scientists said.

Galeras is dominantly andesitic stratovolcano located immediately west of the city of Pasto. It has been active for more than 1 million years.

Major explosive eruptions since the mid-Holocene have produced widespread tephra deposits and pyroclastic flows that swept all but the southern flanks. A central cone slightly lower than the caldera rim has been the site of numerous small-to-moderate historical eruptions since the time of the Spanish conquistadors.

After 10 years of quiescence, Galeras became active again in 1988 and became infamous when its January 4, 1993 eruption killed 6 volcanologists and 3 tourists who were inside the crater when it exploded.

The group was part of a scientific conference excursion and their final decision to enter the crater, pushed forth by team leader Stanley Williams (who miraculously survived), was and still is highly debated.

The fatal decision was made despite the observation of a significantly increased number of particular earthquakes (tornillos), which had preceded previous eruptions and also started to occur in the days before the eruption.

Chile volcano eruptions scares tourists
Tourist captures TERRIFYING moment volatile volcano EXPLODES with ash at holiday resort
A VOLCANO eruption has struck a volatile Chilean site, situated on a busy ski resort, sending a colossal column of smoke 5,000-feet high in the air.

Helpless skiers could do nothing but was the volcanic eruption unfold as they sat stuck on a ski lift at a popular resort in Chile.

The volatile Nevados de Chillán erupted and spewed a 5,000ft plume of smoke, dust and ash into the sky.

Chile’s national emergency office, ONEMI, immediately issued a yellow alert — the second highest on its scale — to communities living close to the volcano.

Gonzalo Llamas Sebesta, an Argentinian holidaymaker, was one of the many tourists who filmed the eruption at the ski resort in the Andes mountains.

The footage, which went viral, was captured while stuck on a ski lift travelling towards the eruption.

In the video, the volcano can be seen erupting just past the ski peak of the mountain.

Despite the chaotic scenes seen in the footage, there have not been any evacuations yet.

Nevados de Chillán volcano, which last experienced a major eruption in 2009, is one of the most active volcanic clusters in the world.

However, the country's Service Nacional de Geología and Minería has been closely monitoring the volcano for the past month.

Since July, there have been a series of earthquakes and other seismic activity associated with explosions from the volcano.

According to Chile's 24 Horas news agency, there are six other volcanoes in the area that have been upgraded in alert status from the National Emergency Office.

There are concerns that the rise in seismic activity puts the surrounding region at risk of a major red-alert eruption in the near future.
Zow..zit je dan ff lekker relaxed in je ski-lift gaat er een vulkaan af... :')

Kuchinoerabu volcano: Japan prepares to evacuate island ahead of feared eruption

JAPANESE authorities are preparing to evacuate a southern island after the threat of a volcanic eruption increased dramatically.

Japan’s Meteorological Agency said volcanic earthquakes and sulphur emissions had increased at a peak on Kuchinoerabujima island, located roughly 1000km southwest of Tokyo, and raised its warning level to 4 out of 5 on Wednesday

The mountain blew its top three years ago, sending ash and smoke thousands of metres into the sky and releasing potentially deadly pyroclastic flows, flows of superheated ash and gas, that reached the sea.

At that time, the island’s entire population evacuated but eventually returned. Some 100 people live there at present.

Japan has 110 active volcanoes and monitors 47 constantly.

When 63 people were killed in the volcanic eruption of Mount Ontake in September 2014, it was the country’s worst such toll for nearly 90 years.

In January, a member of Japan’s military was struck and killed when rocks from a volcanic eruption rained down on skiers at a central mountain resort.

An actual eruption at the peak of Kuchinoerabujima has yet to be detected.

Volcano erupts in North Sulawesi
A volcano erupted Wednesday on the same central Indonesian island as an earlier earthquake and authorities warned planes about volcanic ash in the air.

Mount Soputan in North Sulawesi province spewed ash 6,000 meters into the sky Wednesday morning.

The eruption status was raised from an alert to standby 4 kilometers (2.5 miles) from the summit and up to 6.5 kilometers to the west-southwest. Standby status means the public should avoid the area nearest the volcano and have masks available in the event of ashfall.

No evacuations were immediately ordered.

Planes were warned of the ash clouds because volcanic ash is hazardous for plane engines.

Soputan is on the northern part of Sulawesi island, where a central region was severely damaged by an earthquake and tsunami Friday.

Indonesia, an archipelago of more than 250 million people, sits on the Pacific "Ring of Fire" and is prone to earthquakes and volcanic eruptions. Government seismologists monitor more than 120 active volcanoes.

Explosive-extrusive eruption at Sheveluch volcano, Russia

A gas-steam with ash plume is currently drifting NE of the volcano, KVERT reports.

At 02:30 UTC, volcanic ash was observed rising up to 4.5 and 5 km (14 760 - 16 400 feet) above sea level.

Ash plume/cloud is drifting 70 km (43 miles) WNW of the volcano.

Ash explosions up to 8 - 15 km (26 200 - 49 200 feet) a.s.l. could occur at any time, the observatory warns, adding that ongoing activity could affect international and low-flying aircraft.

A thermal anomaly was identified in satellite images during December 7 and 8 and December 11 - 13. A small explosion on December 12 generated an ash plume that rose 6.5 - 6.8 km (21 300 - 22 300 feet) a.s.l.

That same day a gas-and-steam plume, containing a small amount of ash and drifting 150 km (93 miles) NE, was visible in satellite data.

The Aviation Color Code remains at Orange (the second highest level on a four-color scale).

Sheveluch (also spelled Shiveluch) rises above the lowlands NNE of the Kliuchevskaya volcano group and is one of Kamchatka's largest and most active volcanic structures.

The summit of roughly 65 000-year-old Stary Shiveluch is truncated by a broad 9-km-wide (5.6 miles) late-Pleistocene caldera breached to the south. Many lava domes dot its outer flanks.

At least 60 large eruptions have occurred during the Holocene, making it the most vigorous andesitic volcano of the Kuril-Kamchatka arc.

Frequent collapses of dome complexes, most recently in 1964, have produced debris avalanches whose deposits cover much of the floor of the breached caldera.

Lewotolok volcano (Lembata Island, Indonesia): alert status raised as seismic activity under volcano increases

The volcano observatory raised the alert status of the volcano to 2 ("Waspada" on the Indonesian 1-4 scale), as an increase of volcanic earthquakes and fumarolic activity had been observed during the past week.
The observatory reported a light steam / gas plume rising approx. 500 m above the summit crater of Lowotolok. Since 29 December, the seismic network detected 4 earthquake swarms, one shallow and 3 deeper volcanic earthquakes. This could indicate magma intrusions under the volcano, which could (but not must) lead to a new eruption of the volcano in a near to medium-term future (weeks to months).

Residents as well as visitors and climbers are advised to keep a safety distance of 2 km from the crater. At present, climbing activities have been banned, and residents should remain on alert.

Lewotolok (or Lewotolo) on Lembata Island is one of the region's most active volcanoes. It has erupted on average every few decades, the last time in 1951 and 2012.

Volcano erupts on remote Papua New Guinea island

One of Papua New Guinea's most active volcanoes has erupted, authorities said Tuesday, pummelling villages on a remote island with volcanic rock before subsiding.

Manam island is a volcanic cone that towers out of the sea north of the Papua New Guinea mainland and has a history of eruptions, with major activity in November 2004 forcing the evacuation of some 9,000 people.

The volcano has erupted a number of times since then and spewed lava and ash last month.

A series of tremors around Manam triggered a warning system on Monday and the volcano began erupting shortly after, the Rabaul Volcanological Observatory said.

The eruption continued into early Tuesday, Ima Itikarai of the observatory told AFP.

An observatory report said there were "small ongoing eruptions" from the main crater early Tuesday.

Lava was channelled into a nearby valley and "intermittent bursts" of volcanic rock falling on villages, adding to a heightened risk of mudflows, it added.

The level of sesmic activity declined later in the day after jumping early Tuesday, the agency said.

But it warned that Manam was "still dynamic and volatile and therefore the potential for further eruptive activity in the future is still high".

Papua New Guinea has many volcanoes, particularly on its offshore islands, as the country lies at the junction of two tectonic plates.

Some islanders who were evacuated from Manam 15 years ago and resettled elsewhere on Papua New Guinea recently complained they were still struggling with their new lives, The National newspaper reported.

Volcano in southern Japan erupts; no injuries or damage
A small island volcano in southern Japan erupted Thursday, blasting rocks and ashes into the air but causing no damage or injuries.

Japan Meteorological Agency said the eruption of the Shindake volcano on Kuchinoerabu island sent rocks flying and hot gas and debris pouring down the crater. It has not reached the residential area 2 kilometers (1.2 mile) away, the agency said.

Officials said no damage or injuries have been reported. About 80 residents initially took refuge at a shelter on the island but have since started to return home after an evacuation advisory was lifted less than two hours after the eruption.

Shizuko Goto, an innkeeper, told Kyodo News agency that she felt the ground rattling for several seconds following an explosion and decided to evacuate after seeing a massive cloud of black smoke rise from the volcano.

Chief Cabinet Secretary Yoshihide Suga urged residents to stay calm and follow safety instructions from local officials.

Shindake's last major eruption in May 2015 had temporarily displaced the island's entire population of about 150. The residents were evacuated to Yakushima Island, about 12 kilometers (7.5 miles) to the east.

Only about two thirds of them had since returned to Kuchinoerabu, south of Japan's main southern island of Kyushu.

Central Java prepares for worst as Mt Merapi eruptions increase

KLATEN, CENTRAL JAVA (THE JAKARTA POST/ASIA NEWS NETWORK) - Mount Merapi, which stands on the border between Yogyakarta and Central Java, has shown heightened volcanic activity over the past few days, spewing incandescent lava from its crater.

Sidorejo subdistrict head Jemakir said that apart from incandescent lava, the volcano was emitting booming sounds resembling thunder more frequently, prompting local residents to also increase the frequency of their independently organised patrols.

"The people are still calm because the lava so far has flowed only 500m to 800m down the slope. But we remain alert, in case Merapi erupts," he said on Tuesday (Jan 15).

idorejo subdistrict extends to the slopes of Mount Merapi in the northern part of Klaten regency, Central Java.

Mr Dimas Joko, a volunteer monitoring Mount Merapi, said that the volume and the extent of the lava flow were both relatively normal, but that the volunteer team had banned all human activity within a 3km radius from the cratre.

"They may (still) harvest grass or farm, but they are not allowed within a radius of 3km from the crater," he said.

Citing recommendations from the Centre of Volcanology and Geological Hazard Mitigation (PVMBG), Mr Joko said that people were advised to stay away from the upper slopes of the mountain for their own safety, especially considering the lava flow.

Mount Merapi's warning status on Tuesday was still Waspada (caution), the second of the four-tiered national volcano alert system that has been in place since May 2018.

The Central Java Disaster Mitigation Agency (BPBD Central Java) is working with other regencies to prepare evacuation routes and emergency shelters in anticipation of a major eruption.

BPBD Central Java head Sarwa Pramana said existing Mount Merapi evacuation routes have been heavily damaged by the hundreds of trucks transporting volcanic ash. Conditions have been further worsened by almost daily rainfall in the area.

"Restoring the evacuation routes is very urgent, especially in Klaten. The routes are needed to evacuate people when Merapi's alert level reaches Awas (Danger)," he said.

Mr Sarwa said the most heavily damaged evacuation routes in Klaten included the routes in Kemalang, Manisrenggo and Karangnongko districts. The agency had proposed a budget of 100 billion rupiah (S$9.6 million) to repair the routes.

"I heard that the fund had already been disbursed. Hopefully, construction can begin soon," he said.

Mr Sarwa added that the agency had started calculating logistical needs in case the eruptions worsened, including masks, community kitchens, emergency tents and rehabilitation posts.

"[The calculations] are necessary for smoother mitigation [efforts] at the time of a disaster," he said.

BPBD Central Java had also installed three additional CCTV cameras in Klaten, Magelang and Boyolali to monitor the volcano.

One of the world's most active volcanoes, Mount Merapi is located at the point where four regencies meet: the Central Java regencies of Magelang, Boyolali and Klaten, and Sleman regency in Yogyakarta. At least 353 people were killed and more than 350,000 others were displaced in the 2010 eruption. Most of the victims lived on the volcano's slopes

A strong explosive eruption took place at Bezymianny volcano, Kamchatka, Russia at 16:10 UTC (04:06 local time) on January 20, 2019. The Aviation Color Code was raised to Red. The last major eruption of this volcano took place on December 20, 2017. The latest activity period, which was preceded by a 1000-year quiescence, began with the dramatic 1955-56 eruption.

Explosions sent ash up to 10 km (32 800 feet) above sea level and ash cloud begin to drift northwest, KVERT reported 22:43 UTC.

Activity at the volcano continued with strong gas-steam plume and some amount of ash at a height of about 3.5 - 4.5 km a.s.l., drifting NW.

Deep Quakes Reveal That Magma Is Moving Beneath An Ancient German Volcano

When it comes to active volcanoes, what country first comes to mind? Japan, perhaps? The US? What about Italy? These are all excellent examples, and understandably so. They have a wide range of fiery mountains that, at some point in the last 12,000 years, have erupted – a condition that, per the United States Geological Survey, makes them “active.”

It’s easy to forget that plenty of once-prolific volcanoes around the world have long fallen silent; geologically tame countries were often once replete with effusive or explosive eruptions. Just take Germany’s Laacher See Volcano (LSV), found in the Eifel mountain range within the Rhineland-Palatinate state. This lake-filled cauldron ("caldera") is a rather serene site today, but it was originally forged out of fury. Around 12,900 years ago, a cataclysmic eruption, one that coated plenty of Europe in ash, was responsible for creating the crater-like edifice that we can see there today.

Make no mistake: coming in at a 6 on the Volcanic Explosivity Index (VEI), which tops out at 8, this was an unmistakably huge eruption. Today, according to Volcano Discovery, it’s the only caldera in Central Europe, which means that in the last 12-13,000 years, this part of the world has never seen an eruption as powerful as the one that formed LSV.

Its days of volcanism aren’t necessarily done and dusted, though. A new study, published in Geophysical Journal International, reveals that there are some curious rumblings going on beneath LSV. These specific tremors, known as deep low-frequency earthquakes, are a clear sign that magmatic fluids are on the move.

That's certainly noteworthy. The East Eifel Volcanic Field, of which LSV is part of, hasn’t experienced an eruption for roughly 12,000 years, so the movement of magma beneath the surface is something that volcanologists are keen to document and comprehend.

Laacher See: Eifel-Vulkan ist aktiver als gedacht

Forscher haben immer wieder gesagt, dass die Vulkane in der Eifel noch immer aktiv sind. Sie schlummern einfach seit tausenden Jahren vor sich hin. Genau wie der Vulkan unter dem Laacher See 40 Kilometer südlich von Bonn.

Mikrobeben Zeichen für Aktivität

Seit 2013 verzeichnen Geologen der Landeserdbebendienste immer wieder leichtere Erdstöße unter dem See. Die neusten Erkenntnisse dazu haben die Forscher jetzt veröffentlicht. Menschen können diese sogenannten Mikrobeben nicht wahrnehmen. Allerdings sind sie ein Zeichen dafür, dass sich die Magmakammer wenige Kilometer unter dem Krater allmählich wieder mit flüssigem Gestein füllt. Vermutlich passiert das schon seit längerer Zeit. Modernste Messtechnik macht es inzwischen möglich, diese Beben überhaupt zu registrieren.

Nächster Ausbruch kommt bestimmt

Dass der Vulkan unter dem Laacher See irgendwann wieder ausbricht, gilt unter den Forschern als sicher. Vermutlich wird es aber erst in mehreren tausend Jahren soweit sein. Denn solange wird es dauern, bis sich die Magmakammer unter dem Krater wieder komplett gefüllt hat. Vor knapp 13.000 Jahren ist der Laacher Vulkan zuletzt ausgebrochen. Die Aschewolken wehten bis ins heutige Norditalien und nach Südschweden.

Powerful eruption at Manam volcano
A powerful eruption started at Papua New Guinea's Manam volcano around 04:48 UTC on January 23, 2019. The Aviation Color Code is Red.

The Darwin VAAC first reported the eruption at 04:49 UTC with ash estimated at a height of 12.2 km (40 000 feet) a.s.l.

The eruption is clearly ongoing despite widespread meteorological cloud in the area, the center said 05:32 UTC. Plume to 13.7 km (45 000 feet) appears to be moving W, lower-level emission to 7.6 km (25 000 feet) is moving northeast.

At 07:32 UTC, height was revised to 15.2 km (50 000 feet) and 6 km (20 000 feet) based on the movement of plumes. Volcanic ash to 15.2 km moving west remains discernible, However volcanic ash to 6 km, moving north and east, is obscured by meteorological cloud.

This volcano is experiencing similar high-impact eruptions over the past couple of months. The last one took place on January 11, 2019, with ash plume rising up to 15.2 km a.s.l. An even stronger eruption took place on January 7, up to 16.7 km (55 000 feet) a.s.l. It was the highest plume produced by the volcano since 2015 when VA rose to 19.8 km (65 000 feet) a.s.l.

A sudden, high-impact eruption took place on August 24, 2018, producing lava flows that forced 2 000 villagers to flee to safety.

A major eruption of this volcano forced the evacuation of some 9 000 people in 2004. Many of them still reside at a camp on the outskirts of Madang.

Magmatic recharge detected beneath Laacher See

For the first time since the improvement of the local seismic networks in the East Eifel region, Rhineland-Palatinate, Germany, scientists have detected and located recurrent deep low-frequency (DLF) earthquakes in the lower crust and upper mantle beneath the Laacher See Volcano (LSV), using a joint data set of permanent sensors and a temporary deployment. DLF microquakes suggest mass transport in the volcanic plumbing system and used to infer feeding channels from and into magma reservoirs.

So far, eight DLF earthquake sequences were observed in four distinct clusters at depths between 10 and 40 km (6.2 - 25 miles), scientists report in a study published recently in the Geophysical Journal International.

These clusters of weak events (ML< 2) align along an approximately 80° southeast dipping line south of the LSV. Moment tensor solutions of these events have large shear components, and the irregular dispersion and long coda of body waves indicate interaction processes between shear cracks and fluids.

"We find a rotation of P-axes orientation for shallow tectonic earthquakes compared to DLF events, indicating that the stress field in the depth interval of DLF events might favor a vertical migration of magma or magmatic fluids," authors say.

"The caldera of the LSV was formed by the last major eruption of the East Eifel Volcanic Field only 12.9 kyr ago, fed by a shallow magma chamber at 5 - 8 km (3.1 - 5 miles) depth and erupting a total magma volume of 6.7 km3 (1.6 mi3). The observed DLF earthquake activity and continuous volcanic gas emissions around the LSV indicate an active magmatic system, possibly connected with an upper mantle melt zone."

"We cannot say for sure that a large amount of magma is rising and we don't actually expect an immediate eruption very soon, or in the near future," said Dr. Torsten Dahm, Head of section 2.1: Physics of Earthquakes and Volcanoes at GFZ Potsdam and one of the authors of the new study, in an interview published in Deutsche Welle on February 6, 2019.

"It shows us that there is activity going on, and also magmatic activity. And it's the first time that we have direct evidence, meaning direct in the sense of observing seismic signals. So we know it's really occurring now," Dahm said.

"This is a destructive volcano," Dahm added. "13 000 years ago it erupted with such violence that its ash stopped the Rhine River. I still can't get over that. It makes me wonder, how are we monitoring Lake Laach right now, and what should we improve?"

Asked about CO2 gasses bubbling up in parts of the lake, Dahm said that there is a danger in this region. "And everywhere where you have CO2. As you know, CO2 can be dangerous. I always thought it was forbidden to swim in some areas of Lake Laach, or at least it was not recommended to swim there."
