On March 28, 2025, a magnitude 7.7 earthquake struck the Southeast Asia country of Myanmar along the Sagaing Fault, killing thousands and causing widespread damage. A new study from Caltech uses satellite imaging of the Sagaing Fault's motion to improve models of how such faults may behave in the future. The study indicates that strike–slip faults, like the Sagaing and the San Andreas, may be capable of earthquakes that are significantly different from past known earthquakes and potentially
