At 8:26 on August 24, a magnitude 4.7 earthquake struck Changning County, Yibin City, Sichuan Province, with a focal depth of 5 kilometers. The Chengdu High-tech Disaster Reduction Research Institute, falsely using the name of the 'China Earthquake Early Warning Network,' issued early warning information to the public with a magnitude of 7.7 through channels such as Honor and vivo phones, as well as Xiaotiancai watches. The Sichuan Earthquake Agency had terminated the third-party authorization for providing emergency earthquake information services of the China Earthquake Early Warning Network to the Chengdu High-tech Disaster Reduction Research Institute on July 22, 2026.
