In World First, CCTV Captures Supershear Velocity Earthquake

For the first time ever, a CCTV camera in Myanmar captured real-time footage of a supershear strike-slip earthquake moving at 3.7 miles per second. According to seismologists at Japan's Kyoto University, the analysis has 'led to new findings based on real-time visual evidence of tectonic motion,' reports Popular Science. From the report: The magnitude 7.7 event took place on March 28 along the Sagaing Fault with an epicenter near Myanmar's second-largest city, Mandalay. Although the initial rupture process lasted barely 80 seconds, it and numerous aftershocks were ultimately responsible for 5,456 confirmed deaths and over 11,000 injuries. Later evaluations indicated the quake was the second deadliest in modern history, as well as the most powerful to hit Myanmar in over a century. According to a separate group's paper published in the same journal, the southern portion of the rupture occurred at an astonishing 3.7 miles per second -- fast enough to qualify as 'supershear velocity.'

Amid the catastrophe, an outdoor CCTV camera about 74.5 miles south of the epicenter recorded a visceral illustration of its power. Over just a few moments, what at first looks like a single chunk of the ground appears to suddenly divide and horizontally shift past one another in opposite directions. Completely by accident, the camera recorded a direct look of a strike-slip fault, something previously analyzed by remote seismic instruments. To researchers at Kyoto University, the clip wasn't just a jaw-dropping scene -- it was an opportunity to study a strike-slip fault using visual data. You can watch the footage on YouTube.
