Kick 'Em Jenny is an active submarine volcano located 260 km southwest of Barbados. It was first discovered in 1939 after an eruption caused an ash cloud to rise over the ocean and be seem by people on the island. While difficult to monitor due to the fact that it's underwater, 13 eruptions have been noted since 1939 causing minor tsunamis in Grenada.
Although Barbados is not a volcanically active country, it is near many volcanoes, and therefore they make sure to educate citizens on what to do in the event of an earthquake. They also monitor all seismic activity very closely.
