Details for: Esan
A 618-m-high lava dome tops E-san, a small stratovolcano at the eastern tip of the Oshima Peninsula. E-san is Hokkaido's southernmost active volcano. A minor phreatic eruption in 1846 produced a mudflow that caused many fatalities. The latest volcanic activity at E-san was a small eruption in 1874. Active fumaroles occur at a thermal area on the upper NW flank. Photo by Ken-ichi Arai, 1996 (Hokkaido University).
