What kind of volcano is Reventador?

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

How is seismicity near Reventador 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 Reventador

Stratovolkano curam di lereng timur Andes Ekuador yang berhutan, sekitar 90 km di timur Quito, menjulang di dalam kaldera berbentuk tapal kuda yang terbuka ke arah cekungan Amazon. Letusan eksplosifnya pada November 2002 menghujani Quito dengan abu dan menutup bandara ibu kota, dan sejak 2008 gunung ini hampir terus-menerus meletus dengan ledakan, kolom abu, dan aliran lava di lerengnya.
