Myanmar earthquake coherence map from Sentinel-1

On 28 March 2025, a powerful magnitude 7.7 earthquake struck central Myanmar, sending shockwaves through the region. While the country is still dealing with the devasting aftermath, scientists have used radar images from the Copernicus Sentinel-1 satellites to reveal a detailed picture of how the ground shifted during the quake – offering new insights into the mechanics of the Sagaing Fault and the scale of the seismic rupture.

The image uses data from Sentinel-1A and Sentinel-1C to reveal a ‘coherence map’, where the fault appears as a dark fracture slicing through the land. This coherence map shows areas that have changed between the two acquisition dates as dark tones while stable areas appear bright. These impressive results demonstrate that the new Sentinel-1C satellite is working perfectly and its data can be used with confidence alongside its older Sentinel-1A sibling.
