4 dead, 9 injured [6] Starting on December 28, 2019, [7] and progressing into 2020, the southwestern part of the island of Puerto Rico was struck by an earthquake swarm, [8] including 11 that were of magnitude 5 or greater. [9] The largest and most damaging of this sequence was a magnitude 6.4 Mw, which occurred on January 7 at 04:24 AST (08:24 ...
unknown. The 1787 Boricua earthquake struck offshore of the island of Puerto Rico on May 2. The magnitude of the earthquake was believed to have been around 8.0–8.25, however there is evidence that it was only about 6.9.

Situated just north of the Commonwealth of Puerto Rico, the Puerto Rico Trench separates the Atlantic Ocean and the Caribbean Sea. The ocean trench is a geologically complex site. The Caribbean and North American tectonic plates are scraping by each other, making a huge transform fault that extends from the Puerto Rico Trench to the coast of Central America.
In December 2018, he became the first person to reach the deepest point of the Atlantic Ocean, piloting DSV Limiting Factor, a reported US$50 million submarine system (Triton 36000/2) – including its support ship the DSSV Pressure Drop and its three ultra-deep-sea robotic landers – 8,376 m (27,480 ft) below the ocean surface to the base of the Puerto Rico Trench, an area subsequently ...
Additional publication details. The Puerto Rico Trench, the deepest part of the Atlantic Ocean, is located where the North American (NOAM) plate is subducting under the Caribbean plate (Figure l). The trench region may pose significant seismic and tsunami hazards to Puerto Rico and the U.S.Virgin Islands, where 4 million U.S. citizens reside.
