Summary
A 4.7 magnitude earthquake struck Changning County in Yibin, Sichuan Province on Monday, August 24, at 8:26am, according to the China Earthquake Networks Center. The tremor had a focal depth of just 5 kilometers, classified as an extremely shallow earthquake, resulting in noticeable shaking across the epicenter and neighboring regions . No casualties or property losses have been reported as of press time, with authorities still assessing the situation .
Key Points
- The epicenter was located at coordinates 28.33 degrees north latitude and 104.98 degrees east longitude in Changning County, Yibin
- With a depth of only 5 kilometers, the extremely shallow quake meant seismic wave energy dissipated slowly, intensifying perceived shaking
- Yibin sits on the southern edge of the Sichuan Basin with complex geological structures, making it prone to seismic activity
- An unauthorized institute issued a false 7.7 magnitude warning through smartphone notifications, contradicting the official 5.4 magnitude assessment
- The Sichuan Earthquake Bureau had terminated data-sharing authorization with that institute on July 22 this year
