(5,648 posts)According to Wikipedia, Kick'em Jenny is the only active underseas volcano in the Caribbean and there have been numerous eruptions of that undersea volcano since 1939. It's peak is approximate 180k (591 ft.) under the surface. You can judge for yourself the possible consequences of an eruption based on the narratives of past eruptions. Even the largest eruption cause tsunamis only about 6 feet high on Grenada which is about 8 km (5 miles) to the South. The exclusion zone around the volcano was recently increased to 5 km. Grenada is not a low lying island; it is mountainous since it's origins are also volcanic. In addition its port and largest city, St George's, is on the opposite side of the island.
From Wikipedia: "The first record of the volcano was in 1939,[3] although it must have erupted many times before that date. On 2324 July 1939 an eruption broke the sea surface, sending a cloud of steam and debris 275 m (902 ft) into the air and generating a series of tsunamis around two metres high when they reached the coastlines of northern Grenada and the southern Grenadines. A small tsunami also reached the West coast of nearby Barbados, where 'a sea-wave' suddenly washed over a coastal road.
The volcano has erupted on at least twelve occasions between 1939 and 2001 (the last being on December 4, 2001), although none of the eruptions have been as large as the 1939 one, and most were only detected by seismographs. The larger eruptions have also been heard underwater or on land close to the volcano as a deep rumbling sound."
