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

Un stratovolcan escarpé sur le versant oriental et boisé des Andes équatoriennes, à environ 90 km à l'est de Quito, qui s'élève dans une caldeira en fer à cheval ouverte vers le bassin amazonien. Son éruption explosive de novembre 2002 a couvert Quito de cendres et fermé l'aéroport de la capitale ; depuis 2008, il entre en éruption presque sans interruption, avec des explosions fréquentes, des panaches de cendres et des coulées de lave sur ses flancs.
