Friday, April 9, 2021 — The UWI St. Augustine, Trinidad & Tobago — On April 9, at 8:41 am, an eruption column (cloud of ash) began rising above the La Soufrière volcano located in Saint Vincent and the Grenadines. This signalled that the volcano moved to an explosive phase following three months of effusive eruption, magma extrusion and more recently, tremor and volcano-tectonic (VT) seismic activity.
Leading up to this morning’s eruption, a scientific team at The University of the West Indies Seismic Research Centre (UWI-SRC) has been stationed on the island since December 2020 when activity was first detected. On April 8, the team recorded seven bands of tremor at two and a half hour intervals. A small volcano-tectonic swarm was also detected. Elevated periods of steam and gas venting coincided with the tremor.
