Dr Erouscilla Joseph, a director at The UWI Seismic Research Centre says that as of 7p.m Friday, there had been three ash venting emissions at the La Soufrière volcano on the eastern Caribbean island of St. Vincent since morning.
In an update, Joseph said that the movement was progressing and expected to proceed for the time being.
She said that at a close by observatory, the group there was seeing the debris segment with ash-fall happening at the observatory.
She said the debris was being inspected.
She said lightning and thunder that was being competent at the emission site was because of the charged particles in the ejection segment.
As indicated by researchers contemplating the wonder, the reason for the bolts is friction based electricity, from particles focusing on together thick debris mists close to the ground.
Researchers believe that the charged particles liable for volcanic lightning may begin from both the material catapulted from the spring of gushing lava and through charge development measures inside debris mists traveling through the air.
