(UWI-SRC) Social Share Kingstown – The scientists monitoring the La Soufriere Volcano here are warning that it continues to be in a state of unrest even though seismic activity remains low since the tremor associated with the explosion and ash venting more than a week ago. The Seismic Research Centre (SRC) of the University of the West Indies (UWI), in its latest bulletin, said that in the last 24 hours, only a few long-period, hybrid and volcano-tectonic earthquakes have been recorded and there was no further tremor.
