Puerto Rico Earthquake 2020

Start Date

January 7, 2020

Overview

Since December 28th, 2019 the island of Puerto Rico has been affected by a series of hundreds of small earthquakes, which culminated in a powerful 6.4 magnitude earthquake on the morning of Tuesday, January 7th (Source: https://www.usgs.gov/news/magnitude-64-earthquake-puerto-rico) This Tuesday Earthquake caused widespread damage to infrastructure in a region that is still recovering from the effects of 2017’s Hurricane Maria, leaving more than 2,000 people in shelters, nearly 1 million without power and hundreds of thousands without water as of Thursday January 9th.

The NASA Earth Applied Sciences Disasters Program has activated a “Tier 1” response to the earthquakes in Puerto Rico. As part of this response the program is in contact with federal agencies leading the response effort including the Federal Emergency Management Agency (FEMA), the United States Geological Survey (USGS) and the U.S. Department of Health and Human Services (HHS) to provide NASA Earth-observing data in support of the response and recovery for this disaster.

The NASA Earth Applied Sciences Disasters Program has activated a “Tier 1” response to the earthquakes in Puerto Rico, which entails collecting information and coordinating with stakeholders and university partners. The program is participating in inter-agency calls with federal agencies leading the response effort including the Federal Emergency Management Agency (FEMA), the United States Geological Survey (USGS) and the U.S. Department of Health and Human Services (HHS), along with the Earthquake Engineering Research Institute, to provide NASA Earth-observing data in support of the response...

This map shows ground changes, or displacement, on the eastern two-thirds of Puerto Rico following a 6.4-magnitude earthquake. The ground shifted up to 5.5 inches (14 centimeters) in a downward and slightly west direction. Credit: NASA/JPL-Caltech, ESA, U
NASA scientists are using satellite data to help federal and local agencies identify areas with potential damage. Earthquakes cause permanent changes to the ground surface. By comparing interferometric synthetic aperture radar (InSAR) data acquired on Jan. 9, 2020, with data acquired on Dec. 28, 2019, from the Copernicus Sentinel-1A satellite, the scientists were able to map where, how much and in what direction those changes occurred.

Este mapa muestra los cambios en el terreno, o desplazamiento, en Puerto Rico que se dieron tras un terremoto de magnitud 6.4. El suelo se desplazó hasta 5.5 pulgadas (14 centímetros) en dirección hacia abajo y ligeramente hacia el oeste. Crédito: NASA / JPL-Caltech, ESA, USGS. Los científicos usan datos satelitales para ayudar a las agencias de respuesta a identificar las áreas afectadas. Días después de que un terremoto de magnitud 6,4 sacudiera a Puerto Rico, seguido de...
