CCTV captures earthquake in Myanmar at unprecedented speed

The video recorded a remarkable earthquake event in Myanmar, revealing critical data.

CCTV footage captures unprecedented earthquake dynamics

On March 28, a powerful 7.7 magnitude earthquake struck near Mandalay, Myanmar, along the Sagaing Fault, leading to extensive devastation. This event caused over 5,400 deaths and more than 11,000 injuries. Uniquely, an outdoor CCTV camera recorded the quake's effects, capturing what experts believe is a first in visual documentation of a strike-slip fault. The rupture occurred at a speed classified as supershear velocity, at up to 3.7 miles per second. Researchers at Kyoto University utilized the video for detailed analysis, learning that the fault slipped 8.2 feet in just 1.3 seconds, a significant finding that enhances understanding of earthquake dynamics.

The footage presents a groundbreaking opportunity for scientists to observe an earthquake in real-time. This unprecedented recording not only confirms existing theories about fault movement but also suggests that previously assumed linear patterns might often be curved. Such insights could revolutionize how risk is assessed in earthquake-prone regions. As urban planners seek to design more resilient buildings, the lessons learned from this event may directly influence construction codes and safety measures in the future.

Highlights

Future research may build on these insights to enhance earthquake preparedness globally.
