The volcano—located in the North Pacific—has long been dormant, with its last eruption occurring in 1924.
An astronaut aboard the International Space Station has captured a spectacular image of a volcano with a 2,300ft-wide crater spewing ash into the atmosphere after a powerful eruption.
In the picture, you can clearly see how the cloud rises up in a narrow column before coming to a stop when it meets air of similar density. "The ring of white puffy clouds at the base of the column might be a sign of ambient air being drawn into the column and the condensation of water vapor," he said."Or it could be a rising plume from interaction between magma and seawater because Raikoke is a small island and flows likely entered the water."
Satellite data also indicates that the eruption has spewed out large quantities of gas, namely sulfur dioxide, which may have reached into the stratosphere—the second main layer of Earth's atmosphere which starts between 4.3 and 12 miles high depending on the location above the planet.
