What kind of volcano is Kusatsu-Shirane?

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

How is seismicity near Kusatsu-Shirane 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 Kusatsu-Shirane

Über Japans berühmten heißen Quellen von Kusatsu liegt Yugama, ein türkisfarbener Kratersee, der zu den sauersten der Erde zählt. Im Januar 2018 brach der seit Jahrtausenden für ruhig gehaltene Kegel Moto-Shirane ohne Vorwarnung über einem Skigebiet aus und überschüttete eine Gondel und auf den Pisten übende Soldaten mit Gestein; ein Mensch starb, elf wurden verletzt.
