SO2 flux is an indicator that fresh magma from a deeper source is being degassed.

The UWI SRC in its Friday 21st May update says, seismic activity at La Soufrière, St Vincent has remained low since the tremor associated with the explosion and ash venting on 22 April.

The unit says  only a few long-period and volcano-tectonic earthquakes are being recorded.

Persistent steaming is observable from the observatory once the cloud cover is high enough, the SRC stated.

Thermal anomalies which indicates high temperatures inside the new crater, continue to be detected by the NASA FIRMS alert system.

The SRC says measurements of the sulphur dioxide (SO2) flux were done on yesterday (20 May) and yielded an average SO2 flux of 461 tons per day.

SO2 flux is 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 SRC said.

The volcano is at alert level ORANGE.
