The earthquake caused ~475 km of right-lateral surface rupture on the Sagaing fault in Myanmar. These data were provided provisionally at https://experience.arcgis.com/experience/e40a6967c3ea42dd85bf44037e05482b based on rapid analysis of available satellite data after the earthquake and updated as more information became available. This data release represents the final data compilation. For updated datasets, we provide both provisional and final versions of the datasets, each marked with the date it was released and “provisional” or “final”. These datasets are based on remote sensing and have not been ground checked. These data were mapped rapidly following the March 28, 2025, earthquake to support scientific and humanitarian response. 20250328 20250715 observed Complete None planned Sagaing Fault 95.6246 96.6583 23.2962 18.1817 ISO 19115 Topic Category biota None eathquake; Myanmar; Burma; Sagaing Fault USGS Metadata Identifier USGS:687671dbd4be020e2014bce3 None Myanmar; Burma; Sagaing; Mandalay; Nay Pyi Taw No access constraints.

Surface displacement fields, decomposed into north-south and east-west components, derived from sub-pixel correlation optical satellite images. The PlanetDove scenes were merged into pre- and post-earthquake composite scenes prior to correlation with MicMac. Sentinel-2 and Landsat pixel correlations results were processed using the Caltech COSI-Corr package in two batches based on availability date (20250325-20250330 and 20250327-20250401 for Sentinel-2, 20250316-20250401 and 20250317-20250402 for Landsat 8 and 9). Sub-pixel offsets maps were destriped to mitigate sensor artifacts. 20250401 Raster Grid Cell 56502 9766 1 Universal Transverse Mercator 47 0.9996 99.0 0.0 500000.0 0.0 row and column 10.000204792135982 9.999946904534353 meters WGS_1984 WGS 84 6378137.0 298.257223563 surface_fault_ruptures_20250711_final.shp Attribute Table Table containing attribute information associated with the data set.
