Scientists have discovered a 1,2km high underwater volcano off Grenada's north coast and are tentatively calling it Kick 'em Jack - after its long-known neighbor Kick 'em Jenny.
Jack, discovered on Wednesday, March 18th, is inactive, the scientists said on Thursday.

Eight scientists researching Kick 'em Jenny ran into Jack three kilometres away from Kick 'em Jenny. They found it as they lowered a remote-controlled underwater craft into an area where geologists thought they might find evidence of volcanic activity from Jenny.

"This is a very exciting discovery. Obviously this volcano was there before, it's just that we
are only now discovering it," said one geologist from UWI.

Ships are banned from coming within 1,6km of Jenny, which is nine kilometres from the coast
and, in eruption, stirs up high waves and heats surrounding waters to boiling point.

Both volcano summits are about 168m underwater. Jenny, an actively growing sub-marine
volcano, rises 1,3km from the sea floor and is venting at 268m. Jack has all the features that
makes it a different volcano. Jack joins another 15 dormant volcanoes in the region.
