What kind of volcano is La Soufrière (San Vicente)?

La Soufrière (San Vicente) 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 (San Vicente) 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.

El 7 de mayo de 1902 su erupción mató a unas 1.600 personas, un día antes de que el monte Pelée destruyera Saint-Pierre en la vecina Martinica. Cuando despertó de nuevo en abril de 2021, tras meses de crecimiento de un domo de lava, los científicos ordenaron evacuar a unas 20.000 personas antes de la primera explosión, y nadie murió.
