Ebeko (Sept. 15th) and Sarychev (Sept 12th) volcanoes erupt in Russia

The moderate explosive activity of Ebeko volcano continues with a new explosion sending an ash plume up to 4.5 km a.s.l., that is extending to the south-east from the volcano. Kvert states ash explosions up to 19,700 ft (6 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft and airport of Severo-Kurilsk. – KVERT
