Another explosion was observed at the La Soufrière volcano in St Vincent around 6:15 this morning.
According to the UWI Seismic Research Centre, it resulted in an eruption column roughly 8000 meters high, with an ash cloud seen moving towards the west of St Vincent.
Seismic activity patterns at the volcano have also changed.
The SRC says the period between explosions has now lengthened to more than 40 hours.
Meanwhile two PAHO representatives have been dispatched to St Vincent to support response efforts.
PAHO has also provided 100,000 masks, PPEs and cleaning supplies which left on the Barbados Defence Force Coast Guard vessel, the HMBS Rudyard Lewis.
There are concerns about a possibility of a spike in COVID-19 cases due to the recent lack of water and recent evacuation efforts, which have seen persons crowding into shelters and private homes.
