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

Um dos vulcões mais ativos de Hokkaido. Em maio de 1926, uma pequena erupção fez colapsar parte do cume e derreteu o manto de neve; o lahar percorreu 25 km até às vilas agrícolas de Kamifurano e Biei em cerca de 25 minutos, matando 144 pessoas. Voltou a entrar em erupção em 1962 e em 1988–89 e é vigiado em permanência.
