Largest Underwater Volcanoes

Kick ‘em Jenny, Caribbean Sea

Kick 'em Jenny is an underwater volcano 8 kilometer off the northern coast of the island of Grenada in the Caribbean. She has erupted at least 10 times since discovery in 1939 and has provided scientists with a rare opportunity to learn about the growth and gradual development of submarine volcanoes into islands.

The name Kick 'em Jenny is probably a reference to the force with which she erupted in 1939. Then, sizeable rocks were thrown as high as 300meter above the sea's level. Kick 'em Jenny is part of a chain of volcanoes known as the Lesser Antilles volcanic arc.

This arc is associated with a subduction zone at the eastern boundary of the Caribbean Plate. It is the southern-most active volcano in this arc, and is also the only active submarine volcano there. The summit of Kick 'em Jenny lay at 180-190meter below sea level.
