The UWI SRC in its update on La Soufriere on Thursday 27th May says 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 and volcano-tectonic earthquakes have been recorded.
The Unit says persistent steaming is observable from the observatory once the cloud cover is high enough and thermal anomalies continue to be detected by the NASA FIRMS alert system. These have been persistent since the 22 April explosion.
Thermal anomalies indicate that there is a source of heat within the crater and are most likely from a small body of magma left over, close to the floor of the Summit Crater.
The UWI SRC says measurements of the sulphur dioxide(SO2) flux at La Soufrière were carried out by boat off the west coast on 25 May and 27 May.
Several traverses were completed and yielded an average SO2 flux of 464 and 242 tons per day, respectively. SO2 can be an indicator that fresh magma from a deeper source is being degassed.
The volcano continues to be in a state of unrest. Escalation in activity can still take place with little or no warning.
The volcano is at alert level ORANGE.
