What kind of volcano is サバンカヤ山?

サバンカヤ山 is classified as a Stratovolcano(es) in Peru. Its tectonic setting is Subduction zone / Continental crust (> 25 km).

How is seismicity near サバンカヤ山 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 サバンカヤ山

ケチュア語で「火の舌」を意味する名を持つアレキパ近郊のアンデスの火山で、2016年11月以降ほぼ毎日噴火し、コルカ渓谷に火山灰を降らせています。1990年代の噴火の火山灰は隣のアンパト山の氷を黒く染めて溶かし、1995年に「フアニータ」と呼ばれる500年前のインカのミイラが見つかるきっかけとなりました。
