Lightnings detected near Bogoslof volcano during one hour 7-8 am UTC this morning
Another (the 6th) large explosion seems to be occurring this morning at the volcano. The Alaska Volcano Observatory reported detecting a strong seismic signal (captured on neighboring islands) and a swarm of lightnings typical for large eruption ash plumes near the volcano and extending north (as the ash plume drifts in this direction). ...plus [lire toutes]

Analysis of shoreline change and vent location from the eruption of Bogoslof volcano. The base image was collected on March 19, 2015 and the analysis was conducted on data from December 22, 2016 after the large explosive eruption on December 21, 2016. Note that the location of the vent for the eruption was underwater or near the shoreline on the NE part of Bogoslof Island. Deposits have enlarged portions of the island and are interpreted to be comprised of coarse-grained volcanic ash and blocks of lava. (image: Burton, Bill; Schneider, Dave / AVO / USGS)
No more ash emissions have been detected from the volcano after the violent explosion Wednesday afternoon (16:10 AKST 21 Dec = 01:10 UTC 22 Dec). However, at least minor intermittent volcanic activity seems to have occurred after this powerful explosion as well. ...plus [lire toutes]
