"Study Unveils Myanmar Fault's Role in 2025 Supershear Earthquake Dynamics"

A UCLA-led study reveals that the 2025 magnitude 7.7 earthquake in Myanmar caused a vast supershear rupture along the Sagaing Fault, advancing seismic research and understanding of earthquake dynamics.

• The magnitude 7.7 earthquake struck Myanmar in March 2025, generating a rupture across approximately 530 kilometers of the Sagaing Fault, marking a significant geophysical event.
• A remarkable feature of this earthquake was the 450-kilometer segment that moved faster than the speed of seismic shear waves, categorizing it as a supershear earthquake.
• This study, published in Science, offers new insights into seismology by analyzing the dynamics of seismic waves generated during the earthquake, enhancing our understanding of fault behavior.
