NASA’s ARIA Team mapped damage in Southwestern Puerto Rico after Earthquake

January 16, 2020 |

Pasadena, CA – NASA says that since a magnitude-6.4 earthquake struck Puerto Rico last week, aftershocks near its southwestern coast have been relentless. The frequency and intensity of the aftershocks continue to cause damage on this already-vulnerable part of the island.

NASA scientists are helping local and federal agencies assess the extent of that damage. Using synthetic aperture radar data from the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA), the Advanced Rapid Imaging and Analysis (ARIA) team at NASA’s Jet Propulsion Laboratory and Caltech in Pasadena, California, created a new damage map that includes the southwestern coast near the main quake’s epicenter.

NASA scientists analyze Satellite Data to Map California Quake

July 15, 2019 |

Pasadena, CA – NASA scientists and engineers continue to analyze satellite data for information on fault slips and ruptures a week after two strong earthquakes struck near the city of Ridgecrest in Southern California, 

Their observations are helping local authorities assess damage and will also provide useful information to engineers for designing resilient structures that can withstand ruptures like the ones created by the latest quakes.

NASA uncovers evidence that Southern California fault connects to fault in Mexico

October 9, 2018 |

Washington, D.C. – A multiyear study has uncovered evidence that a 21-mile-long (34-kilometer-long) section of a fault links known, longer faults in southern California and northern Mexico into a much longer continuous system. The entire system is at least 217 miles (350 kilometers) long.

Knowing how faults are connected helps scientists understand how stress transfers between faults. Ultimately, this helps researchers understand whether an earthquake on one section of a fault would rupture multiple fault sections, resulting in a much larger earthquake.

NASA uses satellite images to create Ground Deformation map of Indonesian Quake

NASA’s Jet Propulsion Laboratory

Pasadena, CA – Scientists with NASA/Caltech’s Advanced Rapid Imaging and Analysis project (ARIA) used new satellite data to produce a map of ground deformation on the resort island of Lombok, Indonesia, following a deadly 6.9-magnitude earthquake on August 5th, 2018.

The false-color map shows the amount of permanent surface movement that occurred, almost entirely due to the quake, over a 6-day period between satellite images taken on July 30th and August 5th.

Washington, D.C. – The Moon became a key focus point for NASA in 2017, whether it was blocking out the Sun during one of the most-viewed events in U.S. history, or reinvigorating the agency’s human space exploration plans.

One of the numerous NASA-related activities and actions the Trump Administration did in 2017 was to reconstitute the National Space Council. During its first meeting on October 5th, Vice President Mike Pence directed NASA to develop a plan to help extend human exploration across our solar system, and return astronauts to the Moon in preparation for human missions to Mars and other destinations.

NASA’s FINDER Technology used to search for Victims of Mexico Earthquake

September 26, 2017 |

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

Pasadena, CA – Disaster relief workers on the ground in Mexico City were responding to this week’s 7.1-magnitude earthquake by using a suitcase-sized radar instrument capable of detecting human heartbeats under rubble.

This technology was developed by NASA’s Jet Propulsion Laboratory, Pasadena, California, and the Department of Homeland Security’s Science and Technology Directorate in Washington. FINDER, which stands for Finding Individuals for Disaster and Emergency Response, was developed as a collaboration between the two agencies.

An emergency responder in Mexico City carries an orange case holding a radar instrument called FINDER. This technology can detect the heartbeats of earthquake survivors buried under rubble. It was developed in a collaboration between NASA’s Jet Propulsion Laboratory and the Department of Homeland Security’s Science and Technology Directorate, then licensed to private companies like SpecOps Group, Inc.

NASA says Scientists use new Technology to increase Tsunami Detection

May 21, 2017 |

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

Pasadena, CA – A team of scientists from Sapienza University in Rome, Italy, and NASA’s Jet Propulsion Laboratory in Pasadena, California, has developed a new approach to assist in the ongoing development of timely tsunami detection systems, based upon measurements of how tsunamis disturb a part of Earth’s atmosphere.

The new approach, called Variometric Approach for Real-time Ionosphere Observation, or VARION, uses observations from GPS and other global navigation satellite systems (GNSS) to detect, in real time, disturbances in Earth’s ionosphere associated with a tsunami.

The ionosphere is the layer of Earth’s atmosphere located from about 50 to 621 miles (80 to 1,000 kilometers) above Earth’s surface. It is ionized by solar and cosmic radiation and is best known for the aurora borealis (northern lights) and aurora australis (southern lights).
