St Vincent: UWI Seismic Research updated on the condition of the eruptions from La Soufriere. Seismic activity at La Soufriere remains low since the tremor associated with the explosion and ash emit around noon on 22 April.
In the last 24 hours, only a few long-period and hybrid and volcano-tectonic earthquakes were recorded from La Soufriere. There was no further tremor.
Since the initial depressurization noted immediately following the 9 April’s explosive phase, the continuous GPS network recorded a decrease in horizontal and vertical movement rates.
While the volcano continues to erupt, the pattern of seismic activity over the last few days has been typical of the growth and destruction of lava domes from La Soufriere.
It is estimated that explosions with accompanying ashfall of similar or larger magnitude can occur with little or no warning. Hence, residents need to be careful as the volcano remains at an alert level.
La Soufriere had five effusive explosive eruptions
during the recorded historical period, that is – 1718, 1812, 1902, 1979, and now in 2021.
La Soufriere began an effusive eruption on 27 December,2020, and again violently erupted on 9 April 2021 and continued to erupt. Roughly around 20,000 residents have been evacuated, and 1,450 families have been displaced. Many inhabitants took shelter in public and private places.
Many neighbouring countries and islands have also been affected by eruptions from La Soufriere. Various organisations also came forward to provide assistance and relief supplies to St Vincent and the Grenadines amid volcanic eruptions.
A few days ago, the UN announced one million dollar assistance to St Vincent, whereas Coca Cola has donated humanitarian aid worth US$125,000 to St Vincent and the Grenadines in partnership with Red Cross following the effusive volcanic eruptions from the La Soufriere.
