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

La Soufrière (São 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 (São 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.

A 7 de maio de 1902, a sua erupção matou cerca de 1600 pessoas, um dia antes de o monte Pelée destruir Saint-Pierre, na vizinha Martinica. Quando voltou a despertar em abril de 2021, após meses de crescimento de um domo de lava, os cientistas ordenaram a evacuação de cerca de 20 000 pessoas antes da primeira explosão, e ninguém morreu.
