Based on visual and satellite data, the authors provide information that characterizes the volcanic activity in the Kuril Islands in 2018. Ebeko (Paramushir Island, the Northern Kurile Islands) and Sarychev Peak (Matua Island, the Central Kurile Islands) volcanoes were active in the Kuril Islands. Ebeko Volcano produced a weak (to moderate) explosive eruption in form of steam and ash-gas emissions (about 800 emissions at a height from 2 to 5.5 km). Sarychev Peak activity was characterized by a weak (to moderate) explosions (over the period from September till October the volcano produced at least 10 emissions that reached a height of 2 to 4.5 km). Due to the relatively low emission height and low ash concentration, the activity on Ebeko and Sarychev Peak in 2018 did not pose a serious threat to the international air routes, but could have a certain impact on the local airlines.
