At about 180m below the surface of the sea, and 8km north of Grenada, Kick ?em Jenny is the only known live volcano in the Eastern Caribbean. Also the most frequently active volcano in the region, it was discovered in July 1939 when a cloud of steam and debris broke the sea surface and rose to 275m. This created a series of tsunamis roughly 2m high which reached Grenada?s northern coastline, the southern coast of the Grenadine islands and even Barbados. Kick ?em Jenny is a modern-day demonstration of how many of the volcanic islands of the Lesser Antilles were formed: with each eruption, deposits of volcanic material accumulates around the summit. Boats are expected to observe a 1.5 maritime exclusion zone from the centre of the volcano.
