Rupture propagation is notoriously difficult to observe, as earthquakes large enough to rupture Earth's surface are relatively rare, and they travel at several kilometers per second. In this unique video, we can observe a pulse of slip of the Sagaing Fault as an earthquake rupture propagates past a CCTV camera during the 2025 Myanmar earthquake. The cartoon below the footage is a schematic representation showing the relationship between the traveling earthquake rupture, the ground shaking, and the movement seen in the video. In particular this movie illustrates how the sideways motion you see in the video is actually a pulse propagating laterally along the Sagaing Fault.
