Mainland China's Earthquake Warning Network Misreported a Magnitude 4.7 Earthquake in Changning, Sichuan as Magnitude 7.7 and Issued an Apology
On August 24, 2026, a magnitude 4.7 earthquake struck Changning County, Yibin, Sichuan. The mainland earthquake early warning network once mistakenly issued a strong earthquake warning of magnitude 7.7 shortly after the quake, prompting people in multiple provinces to take cover; the system later automatically corrected itself, and the Institute of Earthquake Disaster Mitigation subsequently issued an apology.
