A new eruption, of mild intensity only, has been occurring at the remote volcano recently, as satellite imagery shows:
Satellite image of Sarychev Peak volcano from 7 Nov 2017 (image: SENTINEL 2 - ESA/Copernicus, annotated by Culture Volcan)
Thermal signals and visible images show increased heat radiation and suggest that mild ash emissions have occurred during or since late October and early November along with the emission of a new lava flow on the volcano's northern flank.
The attached satellite image from 7 Nov shows a gas plume and a thermal signal. The thermal signal has an elongated shape and corresponds to a new lava flow on the northern flank, more than 1 km long. It is unknown when exactly the new eruption started, but the earliest available satellite data with increased heat emission are from late October.
