Director of the Seismic Research Center at the University of the West Indies, St. Augustine campus, Dr. Richard Robertson said that his team will endeavour to give the country at least 48 hours notice if there is a need for persons living close to the La Soufriere volcano to be evacuated.
The volcanologist in a widely viewed press briefing with Prime Minister Dr Ralph Gonsalves and officials of the National Emergency Management Organisation (NEMO) said that there is currently an effusive eruption taking place.
According to the United States Geological Survey, effusive eruption is “an eruption dominated by the outpouring of lava onto the ground (as opposed to the violent fragmentation of magma by explosive eruptions)”.
“Lava flows generated by effusive eruptions vary in shape, thickness, length, and width depending on the type of lava erupted, discharge, slope of the ground over which the lava travels, and duration of eruption”.
Prime Minister Gonsalves indicated that NASA satellites picked up a hot spot on images yesterday and indicated that there has been an increase in the heat signature at the volcano since then following the effusive eruption today.
Residents have been advised that “at relatively short notice, you may get an order to evacuate”.
A team of specialists is expected to arrive in country tomorrow to conduct further studies on the ground with their equipment to measure in a more precise way to advise the civilian authorities.
The alert level has been raised to ‘orange’.
