Abstract This study investigates the coseismic displacement field caused by the Mw 7.7 earthquake that struck Myanmar on March 28, 2025, along a segment of the Sagaing Fault, a well-known, right-lateral strike-slip fault. To such a purpose, a combination of satellite synthetic aperture radar (SAR)-based techniques, specifically Pixel Offset Tracking (POT), Multiple Aperture Interferometry (MAI), and SAR interferometry (InSAR), was applied to multiple Sentinel-1 SAR images covering the broad regi
