VEGETATION DESTROYED, VILLAGES AFFECTED BY HEAVY ASHFALL

The UWI Seismic Research Centre has noted another change in the pattern of seismic activity at the La Soufriere Volcano.

The episodes of high-amplitude tremor are now 2-8 hours apart.
In a bulletin issued at 6pm, the UWI-SRC said three episodes of tremor have been recorded since 6am today, two of them lower-amplitude while the third, at about 5pm, was high-amplitude.

The episodes continue to coincide with periods of enhanced venting or explosive activity.

With assistance from the Coast Guard, scientists were able to tour the entire north coast of St Vincent from Chateaubelair to Georgetown.

“Observations made indicate that pyroclastic density currents (PDCs) had descended several valleys on the southern and western flanks of the volcano and had reached the sea at Morne Ronde, Larikai and Trois Loupes Bay.”

While extensive damage to vegetation was noted in an area extending from Larikai Bay to Turner Bay on the west coast, no other areas along the coast had been affected by PDCs.

However, villages located on the eastern flank of the volcano had been affected by heavy ashfall.

Explosions and accompanying ashfall, of similar or larger magnitude, are likely to continue to occur over the next few days with the chance of PDCs occurring.
