A recent study using satellite imagery of Myanmar's Sagaing Fault suggests that future earthquakes on similar strike-slip faults, like California's San Andreas Fault, could be larger and more unpredictable than past events, emphasizing the need for updated, physics-based seismic models for better hazard prediction.
A 7.7 magnitude earthquake in Myanmar on March 28, 2025, exhibited the fastest rupture velocity in over 20 years, confirmed as a supershear event through satellite and seismic data, with the rupture propagating at nearly twice the typical seismic shear wave speed, likely contributing to intense ground shaking and minimal aftershocks.
A 7.8 magnitude earthquake struck Myanmar in March, causing over 5,000 deaths, with seismologists confirming that the rupture along the Sagaing Fault occurred at supershear velocity, which likely contributed to its devastating impact. The earthquake involved a long rupture with significant slip, and evidence suggests that the rupture's speed and directivity played a role in the widespread damage. Despite the fault's history of large quakes, this event occurred in a relatively quiet segment, highlighting the importance of early warning systems.
