What kind of volcano is La Soufrière (Saint Vincent)?

La Soufrière (Saint 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 (Saint 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.

Il 7 maggio 1902 la sua eruzione uccise circa 1.600 persone, il giorno prima che il monte Pelée distruggesse Saint-Pierre nella vicina Martinica. Quando si risvegliò nell'aprile 2021, dopo mesi di crescita di una cupola di lava, gli scienziati fecero evacuare circa 20.000 persone prima della prima esplosione e nessuno morì.
