Karymsky is one of the most active volcanoes of Kamchatka. In the past two years, single powerful explosions with ash removal up to 8–10 km a. s. l. were noted. The explosive event of April 19, with the rise of an ash cloud up to 10 km a. s. l., occurred against the background of a continuous emission of ash from the volcano. Due to the high cyclonic activity near Kamchatka, the ash cloud on April 19–21 stretched into a 1000 km long band from southeast to northeast. The northern part of the eruptive cloud was drawn into the Arctic zone by another cyclone. The area of the ash cloud was over 246 thousand km2. In addition to the eruptive one, a large cloud of sulfur dioxide was well manifested at the beginning of the eruption. A cloud slightly saturated with sulfur dioxide was observed over the Arctic zone on April 21–22. A detailed description of the explosive event of the volcano and the spread of the ash cloud was performed based on the study of various satellite data in the information system “Remote monitoring of the activity of the volcanoes of the Kamchatka and the Kuriles” (VolSatView,
