NASA reported that the earthquake of June 23 of magnitude 7.4 that occurred in Crucecita, Oaxaca, would have displaced the territory of Mexico by 45 cm.
The United States National Aeronautics and Space Administration, better known as NASA by its acronym in English, published a map obtained from satellite data, from la Japanese Aerospace Exploration Agency (JAXA) ALOS-2 collected before March 31, 2020 and after the earthquake of June 23, in which you can see the displacement of the surface caused by the earthquake,
To date, surface displacement maps have been generated using satellite data of the region, derived from the synthetic aperture radar (SAR) of the Japanese Aerospace Exploration Agency (JAXA) ALOS-2.
Our Disaster Program is studying the effects of the recent 7.4 magnitude earthquake near Oaxaca, Mexico. This surface displacement map, which uses data from @JAXA_en, shows a displacement of almost 0.45 meters near the epicenter https://t.co/iYBLeq02XS pic.twitter.com/3KIgQebMMD

After the earthquake near Oaxaca, a displacement of almost 45 cm has been observed in the epicenter of the earthquake according to the initial analysis. In the image, a full color cycle represents a relative displacement between two points on the ground. Each cycle defines approximately 15 cm of displacements in the direction of satellite line of sight (LHOS).
NASA’s Earth Science Disaster Program has been activated for this event for research purposes, and is coordinating with researchers and partners to produce satellite-based data and images to better understand the event and its impacts.
