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.
