An underwater volcano off the Granada coast is causing a threat to the shipping industry for the island.

Kick ‘em Jenny is off the country’s northern coast.  The threat level of the volcano currently sits at yellow after spending the weekend at the higher orange level.  The yellow threat level means that an eruption of the underwater volcano is possible and that ships should avoid the area of the volcano by a minimum of 1.5 kilometers.

The volcano, despite being 600 feet below the ocean surface, is a threat because a burst of gasses from the volcano could instantly sink a ship in the waters above.  The process, called “degassing”, would make ships suddenly lose their buoyancy and sink.

Plus, hot rocks can shoot out of the water like missiles and endanger other ships in the region.  It could also cause a tsunami depending on the strength of the eruption.

The volcano has erupted a dozen times since being discovered in 1939.  The last major eruption was in 2001.  The volcano is blamed for Grenada’s worst maritime disaster when 60 people died after a ship went right into the ocean over the volcano.

The volcano has been causing hundreds of small earthquakes over the last few weeks.  At one point on Thursday, over 150 quakes were recorded in four-hour period around the volcano.
