⚠Orange Alert for Kick-em-Jenny

With the recent increase in volcanic activity there has been an upgrade from the yellow status to orange for Kick-em-Jenny volcano.

The Seismic Research Centre of the University of the West Indies in Trinidad and Tobago states “Kick ’em Jenny is a submarine volcano located 8km north of Grenada (12.18°N, 61.38°W). The volcano is about 1300m high and 300m wide at its summit, which is currently thought to be about 200m below the surface of the sea. As far as we know, Kick ’em Jenny is the only ‘live’ (likely to erupt again) submarine volcano in the Eastern Caribbean. It is also the most frequently active volcano in the region, erupting at least 14 times since it was discovered in 1939. The most recent eruption of Kick ’em Jenny occurred in April 2017. For details of that and previous eruptions go to news archives. The volcano is currently at Alert Level ORANGE.   “ See link for more information http://uwiseismic.com .

Orange alert indicates a particular course of action. Vessels should therefore observe a 5 km exclusion zone from the site of the Kick-em-Jenny volcano. Interesting to note that most of the Lesser Antilles, including St. Kitts and Nevis, began as submarine volcanoes. The activity of this particular volcano gives a real time look at how these islands were formed. Therefore the effects of the volcano can be ground breaking to marine related fields of research.


The Ocean Explorer of National Oceanic and Atmospheric Administration has indicated “undersea volcanic activity is a constant process that shapes the features of the ocean” and “Submarine volcanoes are also interesting because of the unique habitats they create. Seamounts are often areas of high biological diversity; their shape acts to deflect food-carrying currents upward, attracting a variety of sessile fauna and the crustaceans and fish that feed upon them. In the late 1970s, scientists were shocked to discover that some animals can even metabolize inorganic compounds emitted during volcanic activity, forming unique communities around hotspots of hydro-thermal venting (similar to geyser activity on land).” For more information http://oceanexplorer.noaa.gov/facts/volcanoes.html

One frequently asked question from the UWI Seismic Research Centre is;

Can an eruption from the Kick ’em Jenny submarine volcano cause a tsunami? 

Kick ‘em Jenny is a submarine (underwater) volcano located 9 km north of Grenada. Currently, scientists believe that there is a very small chance that an eruption of the volcano would trigger a tsunami. Measurements of the volcano were taken in 2003 and the results showed that the summit (highest point) of the volcano is quite deep below the surface of the sea, too deep for an eruption of the kind normally seen to trigger a tsunami.
