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

A steep stratovolcano on the forested eastern slope of Ecuador's Andes, about 90 km east of Quito, rising inside a horseshoe-shaped caldera that opens toward the Amazon basin. Its explosive eruption in November 2002 dropped ash on Quito and shut the capital's airport, and since 2008 it has erupted almost without pause, with frequent explosions, ash plumes and lava flows down its flanks.
