La Soufrière's Eruptive History  

1902 Major eruption (VEI=4), killing 1,680 people
1971 Minor eruption confirmed that expanded the crater lake. Dome growth.
1979 Major eruption that produced pyroclastic flows and lava extrusion. Thousands of people were evacuated. No casualties recorded.
2020 After many years of no activity, a new dome started to form next to the existing dome from the 1970's
2021 The dome continues to grow. As of April 9,  activity at La Soufrière has increased with seismic tremors at the summit. This (likely) means that magma is on the move. Dome activity has also increased with moderate thermal hot spots detected. A red alert level has been issued and evacuations are underway. Shortly after this post, the island was rocked by a series of large eruptions which caused widespread devastation. Post April, seismic activity has remained low since.
