Over 3000 seismic activities have rattled Grenada, prompting heightened concerns due to a surge in seismicity at the Kick ‘em Jenny Submarine Volcano, as disclosed by the National Disaster Management Agency (NaDMA) on Monday.
NaDMA said that the University of the West Indies, Seismic Research Center (UWI SRC) advised of increased seismic activity between Friday and early Sunday morning.
According to NaDMA’s statement, the tally of seismic events reached 3,400, with the most significant registering a magnitude of 3.3.
However, the agency noted a gradual decline in both magnitude and frequency, eventually culminating in a near cessation of activity.
Fluctuating activity levels
NaDMA emphasized the unpredictability of seismic behavior at the Kick ‘em Jenny Submarine Volcano, cautioning that activity levels could fluctuate unpredictably.
It further shared that the UWI SRC will continue to monitor the situation and provide updated analyses of the situation.
To facilitate continuous observation, four fully operational seismic stations stationed in the north of Grenada are tasked with round-the-clock surveillance of Kick ‘em Jenny.
Yellow alert status
NaDMA maintains a Yellow alert level for the volcano, signaling a state of restlessness. This designation mandates a 1.5 km exclusion zone around the volcano, urging all marine interests to adhere to safety protocols.
A Yellow alert indicates that the volcano is restless, with seismicity or fumarolic activity above historical levels, or other unusual activity has been observed.
