A historic earthquake struck central Myanmar on March 28, 2025, leaving a trail of destruction behind. The magnitude 7.7 quake, which hit near Mandalay, was the strongest to strike Myanmar in over 100 years and the second deadliest in the country’s modern era.
Researchers at Kyoto University have gained valuable insights into earthquake science thanks to rare footage captured on CCTV. The footage shows the fault moving 2.5 meters in just 1.3 seconds, confirming a pulse-like rupture and curved slip path.
According to corresponding author Jesse Kearse, the brief duration of motion confirms a pulse-like rupture, characterized by a concentrated burst of slip propagating along the fault. The team’s analysis also proves that the slip path was subtly curved, aligning with previous geological observations from faults around the world.
This study demonstrates the power of video-based monitoring of faults in seismology, enabling unprecedented insights into earthquake behavior. By capturing detailed observations like this, scientists can improve their understanding of earthquake processes and enhance their ability to anticipate ground shaking in future large events.
The next phase of research will focus on modeling fault behavior using physics-based models to investigate the factors that control fault behavior as revealed by this analysis.
