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 empinado estratovolcán en la vertiente oriental y selvática de los Andes ecuatorianos, unos 90 km al este de Quito, que se alza dentro de una caldera en forma de herradura abierta hacia la cuenca amazónica. Su erupción explosiva de noviembre de 2002 cubrió de ceniza Quito y cerró el aeropuerto de la capital, y desde 2008 erupciona casi sin pausa, con explosiones frecuentes, columnas de ceniza y coladas de lava por sus flancos.
