Volcanic Activity Continues at La Soufrière, St. Vincent Alert Level Remains at Orange

An advisory by the UWI Seismic Research Centre on May 10th 2021 at 6:00PM reported the following:

  • Seismic activity at La Soufrière, St Vincent has remained low since the tremor associated with the explosion and ash venting on 22 April.

  • In the last 24 hours, only a few long-period earthquakes have been recorded.

  • Measurements of the sulphur dioxide flux at La Soufrière were carried out by boat off the west coast yesterday (9 May) with the assistance of the coast guard. Several traverses were completed and yielded an average SO2 flux of 208 tons per day.

  • The volcano continues to be in a state of unrest. Escalation in activity can still take place with little or no warning.

  • Information regarding coping with the lahar and ash hazards should be disseminated to the public. The mandatory evacuation order of the Red Zone should be rigorously enforced. Caution should be taken in traversing river valleys on the volcano due to the increased risk of lahars during periods of rainfall on the volcano.

  • The volcano is at alert level ORANGE.
