Puerto Rico Natural Hazards: Earthquakes | Peligros naturales de Puerto Rico: Terremotos
January 2020 Aftershock Forecast Report
Informe del pronóstico de la réplica de enero 2020
USGS provides real-time earthquake data, information on historic earthquakes, resources for the most significant earthquakes, and seismicity and ground motions to support future updates to the seismic hazard models for Puerto Rico and the U.S. Virgin Islands. Our seismic research can help establish better building regulations that mitigate earthquake risks and improve public safety. The USGS Earthquake Hazards Program has collaborated with the Puerto Rico Seismic Network and the Puerto Rico Strong Motion Program to provide staff training and assistance with restoration efforts to the network after Hurricane Maria in 2017. Learn more about the seismic network, latest earthquakes, aftershock forecasts, and other earthquake publications on this page.
El USGS proporciona datos sobre terremotos en tiempo real, información sobre terremotos históricos, y recursos sobre los terremotos más importantes, sismicidad y movimientos del suelo para respaldar las futuras actualizaciones de los modelos de peligrosidad sísmica para Puerto Rico y las Islas Vírgenes de los Estados Unidos. Nuestras investigaciones sísmicas pueden ser utilizadas para establecer mejores normas de construcción que mitiguen los riesgos de los terremotos y mejoren la seguridad pública. El Programa de Riesgos por Terremotos (USGS Earthquake Hazards Program) ha colaborado con la Red Sísmica de Puerto Rico y el Programa de Movimiento Fuerte de Puerto Rico para entrenar al personal y asistir con los esfuerzos de restauración de la red sísmica luego del huracán María en 2017.

Latest Earthquakes | Terremotos más recientes
The USGS Latest Earthquakes tool is part of the National Earthquake Information Center, whose mission is to provide a rapid and accurate data about significant earthquakes worldwide. Data from the Puerto Rico Seismic Network (PRSN) and the Puerto Rico Strong Motion Program (PRSMP), both of which operate seismic stations across Puerto Rico, feed into this tool to provide near real-time maps of ground motion. After a significant earthquake occurs, the PRSN communicates the information to other Caribbean nations. Visit the USGS Latest Earthquakes interactive map tool zoomed into the Puerto Rico region here.

Los datos de la Red Sísmica de Puerto Rico (PRSN, por sus siglas en inglés) y el Programa de Movimiento Fuerte de Puerto Rico (PRSMP, por sus siglas en inglés), que operan estaciones sísmicas en todo Puerto Rico, alimentan esta herramienta para proporcionar mapas de los movimientos del suelo en tiempo casi real. Luego de que ocurre un terremoto significativo, PRSN comunica la información a otras naciones caribeñas.

January 2020 Seismic Sequence | La secuencia sísmica de enero de 2020
After the earthquake sequence in January 2020 off the Southwest coast of Puerto Rico, additional seismic monitoring stations were installed by the Puerto Rico Seismic Network, Puerto Rico Strong Motion Program and USGS to provide reliable data about the earthquake's strength, estimate potential damages, and to provide high-quality data to inform aftershock forecasts. Visit this website for the January 2020 earthquake sequence, containing daily news, and other information.
Tras la secuencia del terremoto en enero de 2020 en la costa suroeste de Puerto Rico, fueron instaladas nuevas estaciones de vigilancia sísmica por la Red Sísmica de Puerto Rico, el Programa de Movimiento Fuerte de Puerto Rico y USGS para brindar datos fiables sobre la fuerza de los terremotos, estimar los daños y compartir datos de alta calidad para basar los pronósticos de las réplicas.

Earthquakes and tsunamis in Puerto Rico and the U.S. Virgin Islands
Many earthquakes and tsunamis have occurred in the northeastern Caribbean, where the movements of the Earth's surface plates are rapid and complicated. Future such events pose serious hazards to the 3.7 million people who live in Puerto Rico and the U.S. Virgin Islands.
Map Showing Susceptibility to Earthquake-Induced Landsliding, San Juan Metropolitan Area, Puerto Rico
Analysis of slope angle and rock type using a geographic information system indicates that about 68 percent of the San Juan metropolitan area has low to no susceptibility to earthquake-induced landslides. This is at least partly due to the fact that 45 percent of the San Juan metropolitan area is constructed on slopes of 3 degrees or less, which are too gentle for landslides to occur. The areas wi
Puerto Rico: Marine sediments, terrestrial and seafloor imagery, and tectonic interpretations
Introduction: Puerto Rico is an island situated in the plate boundary zone between the Caribbean and the North American Plates. This is a geologically fascinating, tectonically active region, where the Caribbean Plate has over-ridden the North American Plate and is now sliding past it with strike-slip motion. The details of this tectonic interaction are poorly understood, largely because much of t
Seismic and tsunami hazard in Puerto Rico and the Virgin Islands
Executive SummaryPuerto Rico and the Virgin Islands are located at an active plate boundary between the North American plate and the northeast corner of the Caribbean plate. The region was subject in historical times to large magnitude earthquakes and devastating tsunamis. A major downward tilt of the sea floor north of Puerto Rico and the Virgin Islands, large submarine rockslides, and an unusual
Advances(?) in mitigating volcano hazards in Latin America
The 1980's were incredible years for volcanology. As a consequence of the Mount St. Helens and other eruptions, major advances in our understanding of volcanic processes and eruption dynamics were made. the decade also witnessed the greatest death toll caused by volcanism since 1902. Following Mount St. Helens, awareness of volcano hazards increased throughout the world; however, in Latin America,

This publication is a history of the prominent earthquakes in the United States from historical times through 1970. It supersedes all previous editions with the same or similar titles (see page ii) and, in addition to updating earthquake listings through 1970, contains several additions and corrections to previous issues. It also brings together under a common cover earthquake data previously list
New seismic study begins in Puerto Rico
A new seismological project is now underway in Puerto Rico to provide information needed for accurate assessment of the island's seismic hazard. The project should also help to increase understanding of the tectonics and geologic evolution of the Caribbean region.
