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

Meanwhile, Sarychev volcano exploded on September 12, 2018 ejecting an cloud of ash up to 3-4 km a.s.l. at 19:03 UTC. An ash cloud drifted to the south-east from the volcano. At 21:00 UTC an ash cloud 5.5×6 km in size moved for about 121 km to the south-east from the volcano, before dissipating. Strong ash explosions could occur at any time. – KVERT
