In the Kuril archipelago, a series of small ash eruptions mark the Sarychev peak.

The VAAC Tokyo recorded the presence of ashes at 2,400 meters above sea level.

These first demonstrations in 2019 follow an eruption from September 8, 2018 to October 15, 2018, another from October to November 2017, and the very strong eruption, accompanied by pyroclastic flows from June 11 to July 16, 2009. The latter, object of satellite photos of the plume, is classified from VEI 4.
