Recently, the Kamchatka Peninsula is experiencing an upstick is volcanic activity with the Karymski and Shiveluch volcanoes exploding regularly.
Well, this enhanced activity climaxed over the weekend with a monster Shiveluch volcanic eruption that sent a plume of ash and gas more than 70,000 feet in the sky.
The Volcanic Ash Advisory Center (VAAC) Anchorage reported on a volcanic ash plume rising to a staggering 70,000 ft (21300 m) and moving at 10 kts in NNE direction
This eruption at Shiveluch produced a “huge stratospheric injection” says Diamond, of the Oppenheimer Ranch Project. “We’re talking Plinian, Ultra-Plinian — one of the largest eruptions of the last decade.”
Particulates ejected to altitudes above 32,800 feet (10km), and into the stratosphere, have a direct cooling effect on the planet.
According to Kvert, the growth of the lava dome continues accompanied by a strong fumarolic activity, incandescence of the dome blocks and hot avalanches.
According satellite data, an ash plume on the height 4.5-5 km a.s.l. continues to drift to the north-west from the volcano.
Shiveluch is currently very unstable and ash explosions up to 32,800-49,200 ft (10-15 km) a.s.l. could occur at any time. Such explosive-extrusive eruptions could affect international and low-flying aircraft.
