Minor steam plumes in March 2012

E-san is located in S Hokkaido, the northernmost of Japan's 47 prefectures (figure 1). Recent monthly reports of volcanic activity from the Japan Meteorological Agency (JMA), translated into English, resumed in October 2010. The only recent JMA report on E-san was in March 2012. This is the first BGVN report discussing E-san.

According to JMA, in March 2012 steam plumes rose to heights of

A small-amplitude and short-duration volcanic tremor occurred on 30 March. After that, the number of small volcanic earthquakes increased until early on 31 March. No steam plumes could be observed on 31 March due to cloud cover; however, JMA reported no change in air vibrations or crustal deformation data. Field surveys on 2 April found no change in either the steam plumes from the crater or crustal deformation (GPS).

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.
