Volcano Activity in Russia on July 31 2019 04:56 AM (UTC).



During our pilot expedition to the northern Kurile Islands, we observed the volcano during 16-20 and 26-27 July 2019: Ebeko's northern crater was very active, almost constantly degassing and producing ash-rich eruptions at irregular intervals of typically few hours.

About half of them consisted in small to moderate, but passive ash venting, while the others were explosions that generated ash plumes of typically 1-2 km height and drifting / slowly dissipating rather long distances (few tens of km) mostly towards the NW.

Due to the lack of significant rain lately, the extremely fine-grained brown-gray ash itself seems to cover much of the northern part of the island. Near the volcano (within approx. 2 km), it forms a deposit about 1 cm thick. Ebeko's stronger explosions were sometimes noisy and ejected abundant blocks, some of which were incandescent during the night....
