Volcanic activity in the Kuril Islands in 2018: on the basis of satellite and visual data

The data characterizing volcanic activity in the Kuril Islands in 2018 are given on the basis of satellite and visual data. The Ebeko volcano (Paramushir island, the Northern Kuriles) and Sarychev Peak volcano (Matua Island, the Central Kuriles) were active in the Kuril Islands. On Ebeko volcano a weak (to moderate) explosive eruption occurred, it expressed in regular steam and ash-gas emissions (only about 800 with a height from 2 to 5.5 km). Sarychev Peak volcano was characterized by a manifestation of weak (to moderate) explosive activity (during the period from September till October there were at least 10 emissions to a height of 2 to 4.5 km). Due to the relatively low emission height and low ash concentration, the activity of Ebeko and Sarychev Peak volcanoes in 2018 did not pose a serious threat to international air routes, but could complicate the work of local airlines.
