Last year's massive earthquake in Myanmar could help researchers better predict where the worst shaking will be if the "Big One" hits the San Andreas Fault in California.
The magnitude 7.7 quake hit on March 28, 2025, near the city of Mandalay and shook buildings as far away as Bangkok, 830 miles (1,330 kilometers) away. The death toll was at least 3,700 people. New research that used detailed satellite data and a one-of-a-kind video of the ground rupturing reveals that the fault had a twisty, almost helical shape, which affected the shaking.
The Sagaing Fault in Myanmar that triggered the quake is analogous to many strike-slip faults worldwide that threaten population centers, said Alice-Agnes Gabriel, a geophysicist at the Scripps Institution of Oceanography at the University of California, San Diego and co-author of the new research, which was publis...
