Explosive-extrusive-effusive eruption of Shiveluch volcano, Kamchatka continues. An episode of intense, but short, activity was recorded at Shiveluch volcano, Kamchatka, Russia on June 26/27, 2013. The event was most likely a partial collapse of the existing dome with possible explosions, since the ash emitted was mostly red (indicating it originated from old, altered lava).

Because of the lack of visibility experts at Tokyo VAAC estimated the height of the ash plume at about 10 to 12 km, using the seismic record from the volcano. KVERT reported ashfall SW of the volcano reaching villages Klyuchi (2mm of ash measured) and Lazo (1mm of ash). Ash plumes were extending to the south-east and south-west of the volcano. Two more ash explosions occurred at 17:06 and 22:01 UTC on June 27, 2013. Ash plumes rose up to 7 and 6 km a.s.l., respectively.

Eruption plume from Popocatepétl yesterday

Activity has picked up during the past 2 days, as the preceding earthquake swarm had suggested. CENAPRED reports emissions at a rate of 2 per hour. The more vigorous explosions have produced ash plumes of up to 3 km height. The largest was an explosion yesterday just before 17:30 (local time).
A large SO2 plume is emitted from the volcano and visible on NOAA satellite data.
The alert level remains at "Yellow Phase 2".

June 13, 2013 – JAPAN – After 10 days of almost no activity, the volcano has woken up violently with 3 powerful explosions last night (at 22:05 and 23:58 UTC, ash plumes to 10-13,000 ft) and this morning at 04:26. The eruption this morning appears to be one of the largest explosions for a long time, producing an ash plume rising to 16-20,000 ft (5-6 km) altitude. An SO2 plume is also visible on satellite data. Tokyo VAAC issued a warning of an ash plume drifting SE at flight level 200 (20,000 ft altitude), s. graphic.

Seismic recording from San Cristobal volcano yesterday (CRIN station, INETER)

 

New eruptions occurred yesterday. The volcano produced a series of 7 small ash emissions between 06:45 to 11:43 am (local time). The explosions were very small and ash plumes only rose up to about 100 m above the crater.
The new eruptions were followed by a rise in seismic activity in the form of tremor, which rose to about 3 times normal levels during the afternoon. The tremor pulse was still of relatively low energy and in itself not alarming, as the volcano experiences similar phases of elevated seismicity frequently, but given the recent activity, INETER warns that new explosions, possibly larger in scale, could follow with little warning and that air traffic should avoid the area of the volcano.
