What kind of volcano is La Soufrière (St. Vincent)?

La Soufrière (St. Vincent) is classified as a Stratovolcano in Saint Vincent and the Grenadines. Its tectonic setting is Subduction zone / Oceanic crust (< 15 km).

How is seismicity near La Soufrière (St. Vincent) 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.

Am 7. Mai 1902 tötete sein Ausbruch rund 1.600 Menschen, einen Tag bevor der Mont Pelée auf der benachbarten Insel Martinique Saint-Pierre zerstörte. Als er im April 2021 nach monatelangem Wachstum eines Lavadoms wieder erwachte, ließen Wissenschaftler schon vor der ersten Explosion rund 20.000 Menschen evakuieren, und niemand kam ums Leben.
