Puerto Rico, officially the Commonwealth of Puerto Rico, is an archipelagic island U.S. territory comprised of the eponymous main island of Puerto Rico and 142 smaller islands, including Vieques, Culebra, and Mona. It is located between the Greater and Lesser Antilles in the northeastern Caribbean Sea, east of Hispaniola, west of Saint Thomas, north of Venezuela, and south of the Puerto Rico Trench. Measuring 177 km in length and 65 km in width with a land area of 8,868 sq km, the main island is the 3rd largest in the U.S., 4th in the Caribbean, 29th in the Americas, and 81st in the world, making it the 174th largest country or dependency by surface area. With 3.2 million residents, it is the 2nd largest in the U.S., 4th in the Caribbean, 4th in the Americas, and 31st in the world, making it the 136th largest country or dependency by population.
Earthquakes are caused by movements within the Earth's crust and uppermost mantle. They range from weak events detectable only by seismometers, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history. Below, earthquakes are listed by period, region or country, year, magnitude, cost, fatalities, and number of scientific studies.
The 1946 Dominican Republic earthquake occurred on August 4 at 17:51 UTC near Samaná, Dominican Republic. The mainshock measured 7.8 on the moment magnitude scale and 8.1 on the surface-wave magnitude scale. An aftershock occurred four days later on August 8 at 13:28 UTC with a moment magnitude of 7.0. A tsunami was generated by the initial earthquake and caused widespread devastation across Hispaniola. The tsunami was observed in much of the Caribbean and the northwestern Atlantic Ocean.
The 2003 Dominican Republic earthquake occurred on September 22 at 00:45:37 local time with a moment magnitude of 6.4 and a maximum Mercalli intensity of X (Extreme).
Starting on December 28, 2019, and progressing into 2020, the southwestern part of the island of Puerto Rico was struck by an earthquake swarm, including 11 that were of magnitude 5 or greater. 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 UTC), with a maximum felt intensity of VIII (Severe) on the Modified Mercalli intensity scale. At least one person was killed, and several others were injured.
The 2010 Aguas Buenas earthquake, also referred to as the 2010 Christmas Eve earthquake, occurred on December 24 at 7:43 p.m. local time in Aguas Buenas, Puerto Rico. It measured 5.1 on the moment magnitude scale and had a maximum Mercalli intensity of VI (Strong). The event was the largest in Puerto Rico since May 16th of the same year, and the largest to impact the San Juan metropolitan area since 1975. The earthquake was felt throughout the island of Puerto Rico, the island municipalities of Vieques and Culebra, the American and British Virgin Islands, and even in the Dominican Republic across the Mona Passage.
