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.

Le 7 mai 1902, son éruption a tué environ 1 600 personnes, la veille du jour où la montagne Pelée a détruit Saint-Pierre, sur la Martinique voisine. Lorsqu'il s'est réveillé en avril 2021, après des mois de croissance d'un dôme de lave, les scientifiques ont fait évacuer quelque 20 000 personnes avant la première explosion, et personne n'est mort.
