What kind of volcano is Hakone?

Hakone is classified as a Complex in Japan. Its tectonic setting is Subduction zone / Continental crust (> 25 km).

How is seismicity near Hakone 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 Hakone

Una caldera a menos de 100 km de Tokio, rodeada de pueblos termales y que acoge el lago Ashi. Su humeante valle de Owakudani, donde los huevos cocidos en manantiales volcánicos se vuelven negros, nació en una erupción hace unos 3.000 años; en 2015 una pequeña explosión de vapor elevó allí el nivel de alerta y cerró el valle durante meses.
