Content overview: “Myanmar's 2025 Quake Holds Lessons for California's San Andreas Fault”. The devastating 2025 earthquake in Myanmar, which claimed thousands of lives and caused widespread destruction, has offered scientists a rare look at how a major rupture behaves on a fault with a similar tilt to California's notorious San Andreas. The Sagaing Fault in Myanmar and the San Andreas both have a near-vertical orientation, but subtle differences in their geometry can dramatically alter ground shaking, according to researchers.
By comparing seismic data from the Myanmar event with models of the San Andreas, experts are refining predictions for how a future 'Big One' might unfold in the Golden State. This matters because California's dense urban corridors, from Los Angeles to San Francisco, sit directly atop the San Andreas system, where a magnitude 7.8 or larger quake could cause hundreds of billions in damage and disrupt millions of lives.
