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.

Ngày 7 tháng 5 năm 1902, vụ phun trào của núi đã giết chết khoảng 1.600 người, chỉ một ngày trước khi núi Pelée phá hủy Saint-Pierre trên đảo Martinique gần đó. Khi núi thức giấc trở lại vào tháng 4 năm 2021 sau nhiều tháng mái vòm dung nham lớn dần, các nhà khoa học đã ra lệnh sơ tán khoảng 20.000 người trước vụ nổ đầu tiên, và không ai thiệt mạng.
