The UWI Seismic Research Center (UWI SRC) in its latest update on La Soufriere Volcano in St Vincent says seismic activity has continued to decrease since the tremor associated with the explosion and ash venting on April 22.
It says small lahars were recorded on October 31.
UWI SRC notes current activity is consistent with a period of unrest after an eruption. This can continue for weeks to months.
While volcanic activity has been on a decline, there is the continued presence of near surface hot spots, daily seismic activity and persistent degassing.
There is a small, but not insignificant, possibility that magmatic activity might restart, should there be an influx of new magma from depth.
The volcano is at alert level Yellow.
