A report last night from the UWI Seismic Research Center confirmed that seismic activity at La Soufrière, St Vincent has remained low since the tremor associated with the explosion and ash on 22 April. In the last 24 hours, only a few long-period, hybrid and volcano-tectonic earthquakes were recorded and there was no further seismic tremor.
The seismic network recorded signals from multiple lahars for a period of about six hours starting around 9 am. 4. These lahars most likely took place in all the valleys around La Soufrière with the most intense lahars occurring between 11 am and 12 noon.
The volcano continues to be in a state of unrest. Explosions with accompanying ashfall, of similar or larger magnitude to those that have already occurred, can take place with little or no warning.
The volcano is at alert level Red.
