What kind of volcano is 磐梯山?

磐梯山 is classified as a Stratovolcano in Japan. Its tectonic setting is Subduction zone / Continental crust (> 25 km).

How is seismicity near 磐梯山 monitored here?

Earthquakes within 50 km of the crater are aggregated from 18 seismic networks and checked against a swarm rule that compares the current rate with this volcano's own 30-day background. Ash advisories come from the VAAC centres that are connected.

Volcano 磐梯山

1888年7月15日、水蒸気爆発で山の北側が吹き飛び、岩屑なだれがいくつもの村を埋めて約477人が亡くなりました。土砂は川をせき止めて桧原湖や色鮮やかな五色沼など数百の湖沼を生み、この山体崩壊は後に1980年のセント・ヘレンズ山噴火を理解する重要な手がかりとなりました。
