1692 Jamaica earthquake
The 1692 Jamaica earthquake struck Port Royal, Jamaica on June 7. A stopped pocket watch found in the harbour in 1969〔(Sunken Pirate City at Port Royal )〕 indicated that it occurred around 11:43 a.m. Port Royal was then the unofficial capital of Jamaica, and one of the busiest and wealthiest ports in the West Indies. It was known both as the "storehouse and treasury of the West Indies" and "one of the wickedest places on earth", being a common home port for the many privateers and pirates operating within the Caribbean Sea. The earthquake caused most of the city to sink below sea level and about 2,000 people died as a result of the earthquake and the following tsunami. About 3,000 people died in the days following the earthquakes due to injuries and disease.〔
==Tectonic setting==
The island of Jamaica lies on the boundary between the Caribbean Plate and the Gonâve Microplate. The Gonâve microplate is a long strip of mainly oceanic crust formed by the Cayman spreading ridge within a strike-slip pull-apart basin on the northern transform margin of the Caribbean Plate with the North American Plate. Jamaica was formed by uplift associated with a restraining bend along this strike-slip structure. The focal mechanisms of earthquakes around Jamaica are primarily sinistral strike-slip along WSW-ENE trending faults and minor reverse or thrust motion on NW-SE trending faults.〔 The 1692 event is thought to have occurred on one of these strike-slip faults.
