LA SOUFRIÈRE BULLETIN #64 APRIL 15, 2021 9:00 PM
- Seismic activity at La Soufrière has changed its pattern. The last of a series of bands of tremor ended at about 5:40 am and, unlike all the previous bands, had no strong venting or explosive activity associated with it.
- Since that time, the seismic network has recorded a near constant swarm of long-period and hybrid earthquakes, with three brief episodes of low-level tremor each lasting less than 30 minutes.
- The continuous GPS network shows a signal consistent with depressurization of the magma reservoir, following the initiation of explosive activity on 9th April 2021.
- The GPS stations at Belmont (SVGB) and Georgetown (SVGG), the only two remaining in the network continue to trend NE and NW.
- The volcano continues to erupt although explosive activity appears to have ended at this time. Its current pattern of seismic activity may indicate growth of a lava dome, but this has not yet been confirmed.
- Explosions and accompanying ashfall, of similar or larger magnitude, could restart in the future.
- Alert level remains RED.
- Eighty-eight shelters with 4,161 occupants are now activated.
- Some three thousand seven hundred and eighteen persons (3718) are being housed in private shelter.
- A total of 1,459 families have been displaced so far.
- The National Emergency Operations Center continues to be fully functional operating on a twenty-four hour, around the clock basis.
- NEMO will continue to provide regular updates on activities at the Volcano as they occur.
