The surface displacement caused by this temblor and its predecessor is clear in new images from Japan's Advanced Land Observing Satellite (ALOS-2) satellite.That satellite gathers data using a technique called synthetic aperture radar, which produces detailed measurements of the height of Earth's surface. NASA/JPL. These data products can support search and rescue efforts and determine disaster impact to aid stakeholder efforts in emergency response and recovery.Examples of damage proxy maps (DPMs) generated following the Central Italy M6.2 earthquake on August 24, 2016. NASA's GeoGateway team, led by research scientist Andrea Donnellan, conducted a series of drone flights to map in 3D the post-earthquakes changes in topography and terrain. Earthquakes cause permanent changes to the ground surface. Earthquakes cause permanent changes to the ground surface. NASA scientists are using satellite data to help federal and local agencies identify areas with potential damage. Interferometric SAR (InSAR) analysis was automatically performed by Caltech-JPL ARIA data system. 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.On July 4 and 5 near the city of Ridgecrest in Southern California two large-magnitude earthquakes struck, generating surface ruptures and damaging homes and businesses. About 50 earthquakes occur each day around the world. The location, magnitude and depth of the earthquake created the conditions necessary to cause a tsunami, leading to a tsunami warning being issued for the Pacific coasts of Mexico as well as Central and South America. Damage from two powerful earthquakes of magnitudes-6.4 and 7.1 respectively which rattled Southern California on July 4 and July 5 is visible from space, NASA maps have revealed. On the map, red indicates areas where the ground was changed, or displaced, with darker shades corresponding to more significant displacement. DPMs generated by the Advanced Rapid Imaging and Analysis (ARIA) project and the Copernicus team.
A The map contains modified Copernicus Sentinel data processed by ESA and analyzed by scientists at NASA's Jet Propulsion Laboratory, and earthquake location data from the USG The ground shifted up to 5.5 inches (14 centimeters) in a downward and slightly west direction. Using Global Navigation Satellite System (GNSS) displacement data from the Trans-boundary, Land and Atmosphere Long-term...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. Scientist-Volunteers Map Landslides from Nepal Quakes. This map shows ground changes, or displacement, on the eastern two-thirds of Puerto Rico following a 6.4-magnitude earthquake. The Earth Observatory is part of the Published Jun 4, 2015. Earthquakes cause permanent changes to the ground surface. These instruments include optical (UAVSAR data following the 2010 Mexicali earthquake.On June 23rd, 2020, a 7.4 magnitude earthquake occurred offshore of Oaxaca, Mexico. InSight, the next mission to the Red Planet, will use seismology to see into the depths of Mars. Image of the Day Land Earthquakes (Source: The New York Times,...Interferogram from modified Copernicus Sentinel-1 SAR data acquired 2018/02/17 and 02/05 shows earthquake fault slip on subduction megathrust beneath coast caused up to 40 cm of uplift of the ground surface. Ascending Sentinel-1 SAR interferogram rewrapped to 10cm color contours of line-of-sight surface deformation. NASA's ARIA mission used synthetic aperture radar data to produce a map of damage caused by two strong earthquakes that struck southern California over the weekend. Credit: NASA/JPL-Caltech, ESA, USGSDays after a 6.4-magnitude earthquake rocked Puerto Rico, followed by hundreds of aftershocks, the full extent of damage is only beginning to be realized.NASA scientists are using satellite data to help federal and local agencies identify areas with potential damage.
The color variation from yellow to red indicates increasingly more significant surface change, or damage.

The map covers an area of 155 by 186 miles (250 by 300 kilometers), shown by the large red polygon. As California experiences one of the worst wildfire seasons on record, NASA is leveraging its resources to help.
