Raikoke Erupted For The First Time in 95 Years Captured by NASA Astronauts

Unlike its active neighbors on the Kamchatka Peninsula, Raikoke Volcano on the Kuril Islands seldom erupts. The little, oval-shaped island most recently erupted in 1924 and in 1778.

The asleep period ended around 4:00 a.m. local time on June 22, 2019, when a large plume of ash and volcanic gases released from its 700-meter-wide crater. The event was recorded from space by astronauts aboard the International Space Station.

In the picture above you will see the volcanic plume rising in a thin column and then growing out in a part of the crest known as the ‘umbrella region’. That is the area where the body of the plume and the encircling air balance and the plume stops getting up. [source]
