What kind of volcano is Chimborazo?

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

How is seismicity near Chimborazo 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 Chimborazo

Mit 6.263 m in den ecuadorianischen Anden ist der Gipfel des Chimborazo aufgrund der Äquatorwölbung der sonnennächste Punkt der Erde und der am weitesten vom Erdmittelpunkt entfernte. Der gewaltige vergletscherte Stratovulkan brach zuletzt um 550 n. Chr. aus.
