December 14, 2025, 10:01 a.m., Pacific: I am updating all these posts, and per the GVP:
Most Recent Weekly Report: 27 August-2 September 2025
The University of the West Indies (UWI) Seismic Research Centre (SRC) and the National Disaster Management Agency (NaDMA) reported a period of increased seismicity at Kick ’em Jenny during 27-30 August. A seismic swarm began at around 1000 on 27 August and by 0800 on 28 August the seismic network had recorded around 800 tremors. The largest events were M 2.2-2.4; no reports were received of felt earthquakes in Grenada. Seismicity began to decline through the day. During 1200 on 28 August and 0830 on 29 August the network recorded 72 events, or an average of 3-4 per hour, reflecting decreasing unrest. The largest events were M 1.4-1.8. Unrest further declined and by 1200 on 30 August only one or two tremors per hour were detected. The Alert Level remained at Yellow (the second lowest level on a four-color scale) and the maritime exclusion zone did not change from the radius of 1.5 km.
Update, June 25, 2023, 12:46 p.m., Pacific: Here’s the abstract (jargon alert) from a recent paper on “KeJ.”
Per UWI Seismic, the volcano is at YELLOW alert permanently (except at times of elevated activity).
Here’s the GVP page.
And this tweet has a nice image of the submarine volcano:
Yes, there's a volcano named Kick 'em Jenny in the Caribbean. It's underwater, and scientists from @uwiseismic studied its T-waves from recent eruptions in 2015 an 2017. For their findings, check out this new #BSSA paper. https://t.co/aOqORmgcJy pic.twitter.com/xoAj5MMI37

April 1, 2021: The volcano is still on Yellow alert.
Update: On March 22, UWISRC lowered the alert level to yellow, but the 1.5-kilometer exclusion zone is still in place.
Update, March 15: UWI seismic experts note that the number of quakes at the volcano is dropping. However, Kick-‘Em-Jenny has done that before and then gone on to an eruption, so they are keeping the level at orange for now.

No, seriously, that’s the name of this underwater Caribbean volcano. Here’s a post I did on it at the Clear Sight blog in 2015.
The University of the West Indies Seismic Research Centre has raised the alert level to orange again and has set up an exclusion zone. More details are available in this UPI story.
Per the Kick-’em-Jenny Global Volcanism Program page, the exact details of the current increase in activity are unspecified. A combined British/UWISRC research team recently studied the volcano.
