Major eruption of Bezymianny volcano


Propels ash more than 7 miles above sea level.

A major explosive eruption took place at Russia’s Bezymianny volcano this morning (16 June 2017), propelling ash to 12.2 km (40 000 feet) above sea level, according to the Tokyo VAAC. It is the strongest eruption of this volcano since September 2012.

Bezymianny, now considered one the most active volcanoes in the world, erupted for the first time in recorded history in 1955. Within six months, it produced a total volume of eruptive products over 3 cubic kilometers (0.72 cubic miles).

For comparison, the 1980 eruption of Mount St Helens produced 1.3 cubic kilometers (0.3 cubic miles) of ash.

Prior to its 1955 eruption, Bezymianny had been considered extinct.

  1. That ought to put the SO2 in the stratosphere . Mean while at the YVO geoscientists and interested individuals are watching a quake swarm in progress located ESE of Hebgen Lake since June 12th. So far it is considered to be mostly tectonic but its proximity to the Yellowstone super volcano is interesting. There are other quake swarms recorded north of the caldera near Holmes Hill and Norris Junction. This raises the question, what is putting the pressure on the rocks causing them to crack? Tectonic forces or magmatic intrusion? Or a bit of both perhaps.
