KINGSTOWN, St Vincent – The National Emergency Management Organisation (NEMO) says the elevated volcano-tectonic (VT) earthquakes that began on Tuesday at La Soufriere has stopped.

NEMO said the earthquakes stopped on Friday, and “since then, the only seismic activity being recorded is small low frequency events associated with the growth of the dome”.

According to NEMO, these kinds of events were dominant before Tuesday.

“Their rate of occurrence does not appear to have changed as a result of the volcano tectonic earthquake swarm.”

Last week, Director of NEMO, Michelle Forbes said that people close to the volcano should be prepared to evacuate at short notice.

“We have been saying for the last few months we have to be ready for any sudden change, any quick change,” said Forbes who was a guest on a local programme.

Geologist Professor Richard Robertson, who heads the volcano monitoring team, endorsed Forbe’s comments, saying that the country has been fortunate this time, in that, unlike 1979, when the volcano last erupted, the current eruption began effusively.

“And for the last three months, it’s been erupting quietly.  So people talk about warning of an explosive eruption, the warning you are getting now is your warning. So if you didn’t know in December that this volcano could erupt, you should have known by January, you should have known by February, and you certainly should have known by March,” Robertson said.

“And just in case you didn’t know, the volcano now starts to give you events that are felt and you can actually feel that something is happening,” he said, referring to the volcano earthquakes felt earlier this week.

He said that there is observable burning of the vegetation on the dome of the volcano and earthquakes were being felt.

“I don’t know, people, what other warning you can get that this volcano is erupting; that it can do some nasty things,” said Robertson who added  that people should not panic but should ensure that they have plans in place.

“You have to have plans if you live in the red and orange zones and there is lots of information that NEMO has put out in terms of what you should do. You should have plans that just in case you have to move south, you know what you are going to do and not wait until it actually happens to put the plan in place or, I dare say, expect that somebody else is going to do it for you.

“This volcano is giving you plenty warning; I suggest you take the warning,” Robertson said. (CMC)
