Ebeko volcano (Kurile Islands, Russia): new ash emissions
Sun, 11 Dec 2016, 12:0512:05 PM | BY: T
A new eruptive phase has been occurring at the volcano again since around 8 December this year. Mild explosive activity has been producing intermittent steam and ash plumes that rose a few hundred meters height and were first noted by inhabitants of Sevaro-Kurilsk on 8 December, but are also visible on cloud-free satellite imagery.

These low-level plumes quickly dissipated into northerly directions; they are the first since a short phase of activity in late Oct.
At the moment,- without an analysis of the ash erupted - it is not known whether the ashes contain juvenile magma, i.e. whether the activity is driven by fresh magma or only by overheated fluids (water) in the shallow hydrothermal system. The latter would be a more expected case, as Ebeko volcano's hydrothermal system is very developed and the new explosive activity comes from the area above its center, normally occupied by acid lakes and fields of strong fumaroles.
