The University of the West Indies Seismic Research Centre (UWI SRC) has advised the National Disaster Management Agency (NaDMA) of increased seismic activity at the Kick ’em Jenny (KeJ) Submarine Volcano.
The unrest event began at 10 pm (local time) on the night of Wednesday, 27 August 2025.
Approximately 800 tremors were detected between 10 pm on 27 August to 8 am on 28 August. The largest events measured so far are in the range of Magnitude 2.2–2.4. There have been no reports of these tremors being felt in Grenada. While activity is continuing, its intensity has decreased compared to the start of the unrest.
The UWI SRC will continue to monitor the Submarine Volcano and provide updated analyses of the situation.
Based on the information from UWI SRC, the alert level for Kick ’em Jenny remains at YELLOW. This means that all marine interests should maintain the exclusion zone of 1.5 km.
The last period of unrest at KeJ occurred between 10 and 14 February 2024, during which over 3,400 events were recorded. The maximum magnitude then was 3.3, and no T-phases (explosion signals) were observed.
The National Disaster Management Agency (NaDMA) will continue to monitor the situation and provide updates to the public.
