Kick-'em-Jenny

Kick 'em Jenny, also Kick'em Jenny is an active submarine volcano or seamount at the bottom of the Caribbean Sea 8 km north of the island of Grenada and 8 km west of Ronde Iceland in the Grenadines.

Kick- 'em - Jenny rises 1300 meters above the sea floor on the steep inner western slope of the ridge of the Lesser Antilles. The North American Plate is subject to subduction beneath the Caribbean Plate to the east of this ridge and the volcanic arc of the Lesser Antilles.

Activity

The first report on the volcano appeared in 1939, although it has to be broken many times before. On 23-24. July 1939 broke through the sea surface and an eruption sent a cloud of steam and dust 275 m high in the air and generated a series of tsunamis that was about 2 m high when it reaches the northern coast of Grenada and the southern Grenadines. 2003, the summit reached a height of 180 m below the sea surface. It is believed that this is since the 1960s, so constant.

The volcano has erupted a total of twelve times since 1939, the last time on December 4, 2001. Neither of the eruptions reached the strength of 1939, they were mostly discovered by seismic recording equipment. The larger eruptions could be heard even under water or on land in the vicinity as a deep rumorendes noise.

An underwater expedition discovered in 2003 a crater with active fumaroles, who separated cold and hot gas bubbles. Samples of fresh olivinischem basalt were collected. An arcuate collapse appeared on the western flank of the ridge and was apparently the cause of a submarine landslide, which is 15 km stretched along the slope to the west towards Grenada Basin.

Etymology

The volcano was unknown before 1939, although " Kick'em Jenny " appeared on earlier maps as either the name of a small island that is now called Diamond Rock (or Ile Diamante ), or as the name of the strait between Grenada and Ronde Iceland ( also Ile de Ronde ). The name itself may have a reference to the waters that are sometimes extremely rough.
