The January 6 and 7, 2020, M 5.8 and M 6.4 earthquakes offshore of southwest Puerto Rico occurred as the result of oblique strike slip faulting at shallow depth. History of Earthquakes in Jamaica Jamaica is located in a geologically active area, and is therefore subject to earthquakes (as well hurricanes). The last month has been an extremely active period for earthquakes in the Caribbean. The Caribbean Plateâs most characteristic feature is the active volcanic arc, the Lesser Antilles, which lies along the eastern boundary of the plate. The epicentre of the quake was in the sea between Jamaica, the Cayman Islands and Cuba, at a shallow depth of 6.2 miles (10 km). Road collapsed at many points on the Cayman islands in the 7.7 #earthquake 1 meter high #tsunami warning was â¦ THE CARIBBEAN has been threatened by a tsunami after a 7.6 magnitude earthquake struck near Honduras yesterday, according to the US Geological Survey â¦ Tsunami warnings were issued after a 7.7-magnitude earthquake hit the western Caribbean on Tuesday afternoon.

Here are some of the salient Caribbean earthquakes: Although earlier milder quakes had been reported, the earliest devastating earthquake recorded in the region was the 1692 Jamaica earthquake, which struck Port Royal on June 7 at exactly 11.43 a.m., according to a stopped pocket watch found in the harbor.
