Alaid volcano (Kurile Islands, Russia): new lava flows detected on satellite imagery
Tuesday Jul 12, 2016 10:34 AM | BY: T
Landsat-8 image of Alaid volcano on 8 July 2016 (annotated by Culture Volcan)The new eruptive phase at the remote volcano which had started around 4 July, after a possible pause in activity, continues with dominantly effusive activity.
A recent satellite image allows to determine that fresh lava flows have erupted (or still are erupting) from the summit vent(s) and accumulate in the northern part of the summit caldera.
Judging from the attached high-resolution satellite image, it seems likely that the main vent, a cinder cone that has been forming since the start of the recent eruption last October, remains active, likely with strombolian activity, while the lava flows themselves originate from two (?) flank vents at its northern feet.
