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

Menjulang dari hutan hujan di tepi Amazon, Sangay telah meletus hampir tanpa jeda setidaknya sejak 1628, menjadikannya salah satu gunung api paling terus-menerus aktif di Bumi. Letaknya begitu terpencil sehingga lama dipantau terutama lewat satelit, namun kolom abunya pada 2020 menaburi kota-kota di beberapa provinsi Ekuador.
