What kind of volcano is Tokachidake?

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

How is seismicity near Tokachidake 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 Tokachidake

Uno dei vulcani più attivi dell'Hokkaido. Nel maggio 1926 una piccola eruzione fece crollare parte della vetta e sciolse il manto nevoso; la colata di fango percorse 25 km fino ai paesi agricoli di Kamifurano e Biei in circa 25 minuti, uccidendo 144 persone. È tornato in eruzione nel 1962 e nel 1988–89 ed è sorvegliato giorno e notte.
