What kind of volcano is Iwate Dağı?

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

How is seismicity near Iwate Dağı 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 Iwate Dağı

'Nanbu Fuji' olarak anılan bu 2.038 metrelik koni Morioka şehrinin üzerinde yükselir. 1732 Yakehashiri lav akıntısı hâlâ o kadar çıplaktır ki ulusal doğal anıt olarak korunur; 1998'de deprem sürüleri ve dağın şişmesi patikaları yıllarca kapattı — bu korku onu Japonya'nın en yakından izlenen volkanlarından biri yaptı.
