Grenada acting Prime Minister Elvin Nimrod and researcher from the Seismic Research Unit of the University of the West Indies, St Augustine, Lloyd Lynch have told residents in St George's that the underwater volcano "Kick 'em Jenny" was not expected to erupt and was more likely to "return to sleep."
The unit raised the alert level for possible eruption to orange yesterday.
The Government Information Service, in a release, said an orange alert meant highly elevated level of seismic activities consistent with the small tremors which have been occurring over the past two weeks.
It said the alert also meant all ships must stay outside the five-kilometre exclusion zone of "Kick 'em Jenny".
There have been increased activity at the volcano since last week's 6.4 magnitude earthquake closer to neighbouring Barbados.
Nimrod and Lynch spoke with reporters after an emergency meeting of the National Disaster Management Agency (Nadma) at its headquarters in Grenada yesterday.
Lynch said in Grenada: "What we expect is that over the next couple of days you could have a number of other eruptive episodes. They could be larger, they could be smaller but based on the physical configuration of the volcano we know that the likelihood of this system generating very large explosions which may result in a tsunami, that possibility is quite remote. "
He quickly added he was "not saying that it is impossible."
He said the Government would be advised of all the possibilities as the volcano was monitored.
Lynch stressed: "From a scientific standpoint, we are saying that the possibility of a very large, catastrophic, damaging eruption is very remote.
"Since that episode that lasted for about an hour this morning, the system (volcanic) has ramped down back to the pre-5.15 (am) level (but) we are still getting a number of small earthquakes."
He said there were about four "earthquakes an hour."
Lynch said the system "does not in its present configuration poses large scale danger to coastal communities. Our findings have shown that the major risk is to the marine community, boats that ply between Grenada and the Grenadines."
He said because of the "increased level of activity there was now likely that in an eruption episode the system may have the capability to throw ballistics within an area of about 1.5 to 3 km.
He said that area "should be avoided" as the sailing public could be at risk.
According to Lynch, the undersea volcano remained well below the surface which cancelled any threat of a major tsunami.
Nimrod said there was no need for Grenadians to panic.
"We are appealing to everyone to go about your business, be calm, be watchful but we believe for now we are safe," the acting Prime Minister said.
