What kind of volcano is Sangay?

Sangay is classified as a Stratovolcano in Ecuador. Its tectonic setting is Subduction zone / Continental crust (> 25 km).

How is seismicity near Sangay 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 Sangay

Amazon'un kıyısındaki yağmur ormanından yükselen Sangay, en az 1628'den beri neredeyse aralıksız püskürüyor ve bu onu dünyanın en sürekli aktif volkanlarından biri yapıyor. O kadar uzaktır ki uzun süre esas olarak uydudan izlendi; yine de 2020'deki kül bulutları Ekvador'un birçok ilindeki kasabaları küle buladı.
