What kind of volcano is Tokachi-dake?

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

How is seismicity near Tokachi-dake 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 Tokachi-dake

Einer der aktivsten Vulkane Hokkaidos. Im Mai 1926 ließ ein kleiner Ausbruch einen Teil des Gipfels einstürzen und die Schneedecke schmelzen; der Schlammstrom raste in etwa 25 Minuten 25 km weit bis in die Bauernorte Kamifurano und Biei und tötete 144 Menschen. 1962 und 1988–89 brach er erneut aus und wird rund um die Uhr überwacht.
