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

Hokkaido'nun en aktif volkanlarından biri. Mayıs 1926'da küçük bir püskürme zirvenin bir kısmını çökertip kar örtüsünü eritti; çamur akıntısı yaklaşık 25 dakikada 25 km yol alarak Kamifurano ve Biei tarım kasabalarına ulaştı ve 144 kişiyi öldürdü. 1962'de ve 1988–89'da yeniden püskürdü ve gece gündüz izleniyor.
