Sarychev Peak (Russian: вулкан Пик Сарычева, Vulkan Sarycheva, variants: Japanese: 芙蓉山 Fuyō Mountain,[1] Fuyō-san,[2] Fuyō-yama,[3] Fuyo-zan,[4] Huyō San, Japanese: 松輪富士 Matsuwa-fuji)[5] is an active stratovolcano covering almost the entirety of Matua Island in the Kuril Islands, Russia.

[6] The peak was named after admiral Gavril Sarychev of the Imperial Russian Navy.

[citation needed] The volcano erupted June 11–21, 2009,[7][8] sending out ash plumes.

[10] During an early stage of the eruption, on June 12, 2009, the International Space Station passed overhead and astronauts photographed the event.

[11] A hole in the overhead clouds, possibly caused by the shock wave from the explosion, allowed a clear view of the plume and pyroclastic flow down the sides of the mountain.
