What kind of volcano is 箱根山?

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

How is seismicity near 箱根山 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 箱根山

距离东京不到100公里的一座破火山口，四周环绕着温泉小镇，怀抱芦之湖。冒着蒸汽的大涌谷约在3000年前的一次喷发中形成，用火山温泉煮的鸡蛋在这里会变成黑色；2015年那里发生了一次小规模蒸汽爆发，警戒级别随之提高，山谷关闭了数月。
