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

Salah satu gunung api paling aktif di Hokkaido. Pada Mei 1926 letusan kecil meruntuhkan sebagian puncak dan melelehkan lapisan salju; lahar meluncur 25 km ke kota pertanian Kamifurano dan Biei dalam sekitar 25 menit dan menewaskan 144 orang. Gunung ini kembali meletus pada 1962 dan 1988–89 dan dipantau sepanjang waktu.
