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

Sobre las famosas aguas termales de Kusatsu se encuentra Yugama, un lago de cráter turquesa que figura entre los más ácidos del planeta. En enero de 2018 el cono Moto-Shirane, que se creía tranquilo desde hacía miles de años, entró en erupción sin aviso sobre una estación de esquí y lanzó rocas sobre una telecabina y sobre soldados que entrenaban en las pistas; murió una persona y once resultaron heridas.
