Astronauts and several satellites captured images of the volcanic eruption from space early Saturday morning.
The plume from the eruption may have reached an altitude of 8 miles high, according to the Volcanic Ash Advisory Centers in Tokyo and Anchorage.
Raikoke is an uninhabited volcanic island in the northwest Pacific Ocean, off the coasts of Russia and Japan.
A thick plume of volcanic ash rises above the dense cloud cover in this close-up #Himawari8 view of the #Raikoke volcano's eruption.
This was the volcano's first eruption since 1924.
"It reminds me of the classic Sarychev Peak astronaut photograph of an eruption in the Kuriles from about ten years ago."
