Earthquake swarm under Takawangha volcano
An energetic earthquake swarm was detected under Alaskan Takawangha volcano on January 23, 2017, prompting the Alaska Volcano Observatory to raise Aviation Color Code to Yellow and Alert Level to Advisory on January 24. The last known eruption of this volcano took place in 1550.

The earthquakes are located 6 to 7 km (3.7 to 4.3 miles) ESE of Takawangha Volcano. Two of them had magnitudes above 4; M4.1 and 4.4 at a depth of 7 and 10 km (4.3 and 6.2 miles), respectively

"This activity may be due to brittle failure in the surrounding rock caused by magma movement," AVO said and raised the Aviation Color Code to Yellow and Alert Level to Advisory. No eruptive activity has been detected in satellite data.

The seismicity has waxed and waned over the past 24 hours, the observatory reported late January 24.

The last known eruption of this volcano took place in 1550, Volcanic Explosivity Index is unknown.

Parts of Takawangha's edifice are hydrothermally altered and may be unstable, possibly leading to localized debris avalanches from its flanks. Takawangha lies across a saddle from historically active Tanaga volcano to the west.

Geological summary
Takawangha is a 1449-m-high, youthful volcano with an ice-filled caldera on northern Tanaga Island, near the western end of the Andreanof Islands. Takawangha lies across a saddle from historically active Tanaga volcano to the west; older, deeply eroded volcanoes lie adjacent to Takawangha on the east.

The summit of the dominantly basaltic to basaltic-andesite volcano is largely ice covered, with the exception of five Holocene craters that during the last few thousand years produced explosive eruptions and lava flows that reached the lower flanks of the volcano.

No historical eruptions are known from Takawangha, although radiocarbon dating indicates explosive eruptions have occurred within the past several hundred years. (GVP)

A very strong explosion occurred at Mexican Colima volcano at 13:45 UTC on January 25, 2017. This is yet another strong explosion at the volcano, currently one of the most active in the world.

The eruption was accompanied with pyroclastic flows on the NE flank.

The Washington VAAC reported volcanic ash drifted NE and reached 7 km (23 000 feet) above sea level at 14:15 UTC.

Alaska volcano erupts again, sending up another ash cloud

A volcano in Alaska's Aleutian Islands has erupted again, sending a cloud of ash and ice particles 30,000 feet in the air.

The Alaska Volcano Observatory says the cloud was seen by satellite shortly after Bogoslof (BOH-gohs-lawf) Volcano erupted Thursday.

Volcanic ash above 20,000 feet is a threat to airliners flying between Asia and North America. The Aviation Color Code was lowered from red to orange late Thursday evening after the ash cloud dissipated.

The volcano 850 miles southwest of Anchorage has erupted more than 25 times since mid-December and could keep up its periodic eruptions for months.

The cloud Thursday drifted southeast at lower altitudes. No ash was expected to fall on nearby Unalaska Island, home to one of the nation's largest fishing ports, Dutch Harbor.
Seismic activity returned to low levels after the eruption.

Powerful eruption at Bezymianny volcano
A powerful eruption took place at Bezymianny volcano, Kamchatka, Russia around 03:00 UTC on March 9, 2017. The Aviation Color Code was first raised to Orange, then to Red.

Tokyo VAAC said at 03:42 UTC, that an eruption at Bezymianny at 03:00 UTC sent ash up to 10 km (33 000 feet) extending N-NW.

According to satellite data by KVERT, ash plume at the height about 7 km (23 000 feet) a.s.l. drifts for about 112 km (70 miles) to the northwest from the volcano, KVERT said at 05:11 UTC. The width of ash plume is about 14 km (8.7 miles). Strong gas-steam activity of the volcano continues, it said.

Strong ash explosions up to 15 km (49 200 feet) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Based on KB GS RAS (Kamchatka Branch of Geophysical Services, Russian Academy of Sciences) data, KVERT noted that seismicity at Bezymianny began to increase on November 18, 2016. The temperature of a thermal anomaly detected in satellite images increased on December 5, and then significantly increased on December 13, which was likely caused by lava-dome extrusion. The Aviation Color Code was raised to Orange.

The Tokyo VAAC noted that ash plumes rose as high as 6.1 km (20 000 ft) a.s.l. on December 15. A gas-and-steam plume containing a small amount of ash drifted about 118 km (73 miles) W.

The last strong explosive eruption at Bezymianny occurred on September 2, 2012 when ash plumes rose to altitudes of 10 - 12 km (32 800 - 39 400 ft) a.s.l. and drifted more than 1 500 km ENE (932 miles).

Kambalny volcano erupts after 248 years of sleep
A major eruption started at Kamchatkan Kambalny volcano at 21:20 UTC on March 24, 2017, prompting authorities to raise the Aviation Color Code to Orange. According to experts, the sharp intensification of the volcano was a complete surprise. Although there are reports of an increase in activity in 1769, the last major eruption of this volcano took place in 1350.

At 21:20 UTC, KVERT said satellite data showed an ash plume about 35 km (21.7 miles) southwest from the volcano. Volcanic cloud was reaching a height of 5 - 6 km (16 400 - 19 680 feet). By 01:34 UTC on March 25, the plume was already about 100 km (62 miles) SSW from the volcano and by 13:24 UTC it was 550 km (341 miles) SSW. At the time, satellite data showed volcanic cloud reaching 5 km (16 400 feet).

An explosive eruption of the volcano continues, KVERT said. Ash explosions up to 6 - 8 km (19 700 26 200 feet) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

"This is the first scientific observation of a major volcanic event at Kambalny," said Olga Kirin, head of KVERT group. "According to tephrochronology, a strong eruption occurred 600 years ago, but there is information about the increase in activity some 250 years ago," she added. "The volcano is under our close supervision, but it is hard to say what will happen next."

The nearest settlement is located some 77 km (47.8 miles) away from the volcano.

Sudden increase in seismic activity under San Miguel volcano, El Salvador

El Salvador authorities are reporting a sudden increase in seismic activity under San Miguel volcano on Tuesday, April 18, 2017. The last major eruptive phase of this volcano started on December 29, 2013, and ended in August 2014 (VEI 2).

In a special report released 20:30 local time on April 17, 2017 (02:00 UTC on April 18), MARN reported a sudden increase in internal seismic vibration was recorded under San Miguel volcano, also known as Chaparrastique, between 00:20 and 00:30 UTC on April 18. The number of earthquakes reached 356 in a period of 10 minutes.

"These variations are associated with the movement of magma inside the crater, typical situation in an active volcano," the Ministry said.

Given the behavior recorded in the past couple of days, the emission of gasses and/or magma from the central crater or from the flanks of the volcano can be expected.

Authorities are urging the population to stay away from the volcano.

An explosive eruption at San Miguel that began at 10:30 local time on December 29, 2013, prompted an evacuation of 1 400 - 2 600 people. A dense ash plume rose from the crater and eventually reached an altitude of 9.7 km (32 000 feet) above sea level. It was the first significant eruption at the volcano since 2001 (VEI 1).

Noodtoestand na vierde vulkaanuitbarsting op rij in Guatemala

In Guatemala is de noodtoestand uitgeroepen in de omgeving van de Vuurvulkaan. De Volcn de Fuego kwam deze week voor de vierde keer dit jaar tot uitbarsting en stoot een twee kilometer hoge aswolk uit.

Vanaf de 3763 meter hoge vulkaan lopen twee lavastromen naar beneden die dorpjes in de buurt bedreigen. 330 mensen moesten worden gevacueerd en tien scholen moesten worden gesloten. Er zijn voor zover bekend nog geen slachtoffers gevallen.

Actiefste vulkaan
De bewoners van de dorpen kunnen voorlopig nog niet terug naar hun huizen. Door de hevige regenval bestaat het gevaar van steenlawines en aardverschuivingen, meldt een organisatie die aardbevingen en vulkaanuitbarstingen monitort.

De Vuurvulkaan, die vijftig kilometer ten zuidwesten van de hoofdstad Guatemala-Stad ligt, staat bekend als de actiefste op het Amerikaanse
