Klyuchevskoy Volcano is one of the most active volcanoes in the world. The 2019–2020 explosive-ef-fusive eruption of the volcano lasted 8 months. The explosive eruption manifested itself in Strombolian and, more rarely, Vulcanian activity. Explosions raised ash up to 7 km above sea level, and ash plumes moved up to 500 km in different directions from the volcano. The main area of the territory where ash falls were noted was more than 60 thousand km2. The effusive phase of the eruption began on April 18, 2020, and lasted almost 2,5 months until the end of the eruption. On April 18–30, 2020, the high-est temperature of the thermal anomaly in the volcano area and the densest ash plumes were noted, in which, in addition to fresh ash, material from collapses from the sides of the Apakhonchich chute was mixed. The lava flow was 1,5 km long; mud deposits covered an area of about 1,7 km2. The paper describes the course of the eruption, and the events preceding it based on the study of video and vari-ous satellite data in the information system “Remote monitoring of the activity of the volcanoes of the Kamchatka and the Kuriles” (VolSatView, http://kamchatka.volcanoes.smislab.ru.
