The Mw7.7 Myanmar earthquake: a continental longest surface-rupturing supershear cascading event
Utilizing the pixel offset tracking and optical satellite imagery, this study interpreted the 2025 Myanmar Earthquake(Mw7.7) distribution and segmentation of surface ruptures along the Sagaing fault. The total length of the surface rupture is estimated to be 465 ± 25 km, predominantly characterized by supershear rupture propagation. This rupture process generated distinct near-fault strong ground motion spectra, which played a critical role in the earthquake’s devastating impact.
