ST GEORGE’S, Grenada, Tuesday May 2, 2017 – The University of the West Indies (UWI) Seismic Research Centre (SRC) is monitoring increased activity at underwater volcano Kick ’em Jenny following scores of eruption over the past few days, but it says there’s no tsunami threat so far.

The Trinidad-based SRC said the first eruption at the region’s only submarine volcano – which is located about five miles north of Grenada – occurred on Saturday around 5:45 pm, with reports of it being felt in St Patrick’s, Grenada.

In its update yesterday, Grenada’s National Disaster Management Agency (NaDMA) said at least 43 “mostly low magnitudes volcanic earthquakes” – in the magnitude range of 1.5 to 2.3 – had occurred between that first tremor and 10:41 a.m. yesterday. There were a few larger events with the largest at magnitude 3.0.

On Sunday, the UWI/SRC recorded a high amplitude signal, lasting about 25 seconds, on one of the Grenada stations. The signal was also recorded on a station in Montserrat.

“This signal follows an increase in the number of background events associated with the Kick ’em Jenny volcano,” the SRC said in a release on Sunday.

As a result of the eruptions, the Kick ’em Jenny alert has been raised to yellow, which means sea users and ships should stay away from vicinity of the volcano and observe a 1.5 km/0.93 mile exclusion zone. However, as a precautionary measure, the SRC said the marine community should observe a 5 km/3.1 mile exclusion zone.

A yellow alert means the volcano is restless, seismicity and/or fumarolic activity are above the historical level, or other unusual activity has been observed or can be expected without warning.

Despite the activity, SRC stressed there was no tsunami watch or warning in place.

“Recent measurements have indicated that the summit of Kick ’em Jenny is currently too deep beneath the surface of the sea for an eruption to likely trigger a tsunami,” it said on Sunday.

However, noting that volcanic episodes at Kick ’em Jenny, since 1939, usually consist of several eruptions lasting over several days before returning to rest, the SRC said further eruptions should be expected during this episode.

    I think this is irresponsible reporting to grab headlines…the word “explodes” is hardly the correct adjective as it plants a seed of fire, lava, pyroclastic flow, tsunami etc etc in the readers mind,
    which its hardly what we want to advertise as a tourist island.

    Thanks for reporting the truth about Kick em Jenny. The public needs to know updates especially islanders in proximity to Grenada. Some people don’t even know there’s an underwater volcano near Tobago or Trinidad. Your reports will prepare them for a pending disaster. Hopefully they will be sensitive to their environment and go to higher ground to escape a tsunami and keep safe during an earthquake.

    wow

    Scientists are not God. They can not see the future. Who knows if, and when it will erupt. Everyone should not panic but still be on the alert.

      I agree with you.
