Bezymianny vulkaan (Kamchatka): toenemende activiteit & uitbarsting waarschuwing
Wednesday Mar 07, 2012 16:18 PM | DOOR: T
De externe Bezymjanny vulkaan in Kamchatka zou dicht bij een uitbarsting, als haar seismische activiteit voortdurend toeneemt, het Russisch Instituut voor vulkanologie en Seismologie (KVERT) gisteren gemeld.
Sterke as explosies tot 42.640 ft (13 km) boven de zeespiegel zijn te allen tijde mogelijk. Lopende activiteiten van invloed kunnen zijn internationale en laagvliegende aircraft.Seismic activiteit begon te stijgen op 12 februari, toen ongeveer 7-19 zwakke seismische evenementen werden geregistreerd elke dag tot 29 februari
Tijdens 01-05 maart, dit aantal steeg tot ongeveer 25 tot 43 zwakke seismische gebeurtenissen en episoden van vulkanische tremor. KVERT waarschuwt dat de activiteit zou kunnen wijzen op een opbouw naar een grotere uitbarsting.
According to satellite data, both size and brightness of a thermal anomaly (a growing lava dome) at the summit abruptly increased on 2 March and continues to increase.

Bezymianny volcano (Kamchatka, world) activity update: high levels of seismic activity, thermal anomaly
Tuesday, Feb 28, 2012
KVERT reported high levels of seismic activity at Bezymianny during 17-24 February and a thermal anomaly that was detected daily in satellite images. Two short volcanic tremor episodes were reported on 15 and 22 February. Gas-and-steam plumes, observed in satellite images, drifted NE on 20 and 22 February. ... [meer...]
Bezymianny volcano (Kamchatka, world) activity update: increased seismic activity, thermal anomaly, probably growing lava dome
Thursday, Feb 23, 2012
KVERT reported that seismic activity increased at Bezymianny on 12 February and remained elevated through 19 February. The size and brightness of a thermal anomaly observed in satellite images both increased during this interval. Blocks possibly extruded from the top of the lava dome. KVERT raised the Aviation Color Code to Orange on 19 February. ... [meer...]

Earthquakes were detected in the vicinity of Bezymianny's lava dome during 23-24 May. Fumarolic activity was seen on 21 May and the temperature of the thermal anomaly detected in satellite imagery increased from 18 degrees Celsius on 19 May to 48.8 degrees Celsius on 23 May. So a increase of activity is possible. During 21-28satellite data showed a thermal anomaly over the lava dome and fumarolic activity was detected.Seismic data indicated that an explosive eruption began on 1 June, producing a large ash cloud about 127 by 93 km in dimension. Ash plumes from two explosions rose to altitudes of 8-10 km (26,200-32,800 ft) a.s.l. Ashfall was reported in Kozyrevsk village. Two bright thermal anomalies were seen in satellite imagery, possibly from pyroclastic flow deposits. [meer...]

KVERT reports that Bezymiany's activity has been increasing, promting to raise the alert code from Yellow to Orange, which means that a new eruption could happen in the near future. Although the seismic data are blurred by the activity of nearby erupting Klyuchevskoy volcano, Bezymiany is showing an increase in earthquakes as well as an increase in the temperature in its crater, the usual preceding signs of new activity.
