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 de los volcanes más activos de Hokkaido. En mayo de 1926 una pequeña erupción derrumbó parte de la cima y derritió la capa de nieve; el lahar recorrió 25 km hasta los pueblos agrícolas de Kamifurano y Biei en unos 25 minutos y mató a 144 personas. Volvió a entrar en erupción en 1962 y en 1988–89 y se vigila las 24 horas.
