#PPOD: Raikoke Volcano on the Kuril Islands rarely erupts. The small, oval-shaped island most recently exploded in 1924 and in 1778. The dormant period ended around 4:00 a.m. local time on June 22, 2019, when a vast plume of ash and volcanic gases shot up from its 700-meter-wide crater. Astronauts at the International Space Station observed a thick plume rise and stream east as it was pulled into a storm's circulation in the North Pacific. Credit: NASA
