Sichuan 4.7-Magnitude Quake Triggers False 7.7 Alert; Research Institute Faces Scrutiny
Crhk · 4 SOURCESabout 2 hours ago3 MIN
Summary
A 4.7-magnitude earthquake hit Changning County in Yibin, Sichuan Province on the morning of August 24, 2025. However, residents across China received dramatic earthquake early warning notifications showing a 7.7-magnitude quake—a massive discrepancy from the actual seismic event. The China Earthquake Administration has confirmed that the Chengdu High-Tech Disaster Reduction Research Institute was solely responsible for issuing the false 7.7 alert under the unauthorized banner of the official China Earthquake Early Warning Network. The incident affected over 10 million users across multiple channels, prompting widespread public concern and triggering official investigations into the institute's practices.
Key Points
- The actual earthquake measured 4.7 magnitude with a focal depth of 5 kilometers, occurring at 8:26 AM on August 24 in Changning County, Yibin, Sichuan. No casualties or property damage were reported .
- The official China Earthquake Early Warning Network correctly issued a 5.4-magnitude alert within 6 seconds after the quake struck, reaching over 10 million users through WeChat mini-programs, Huawei devices, Xiaomi phones, and dedicated earthquake warning terminals .
- The Chengdu High-Tech Disaster Reduction Research Institute simultaneously pushed a 7.7-magnitude alert through Honor, Vivo, and Meizu smartphones, as well as Xiaotiancai children's watches, affecting users nationwide .
- The Sichuan Earthquake Bureau terminated its cooperation agreement with the institute on July 22, 2025, citing multiple violations dating back to 2023-2025, including unauthorized earthquake warning broadcasts in Zhejiang, Shaanxi, Ningxia, Shanxi, and Henan provinces .
- The research institute, founded by Dr. Wang Tun following the devastating 2008 Wenchuan earthquake, issued an apology stating the 7.7-magnitude reading represented data from the fifth second of the warning sequence, which was the largest deviation in 15 years of operation since September 2011 .
Why It Matters
This incident exposes critical vulnerabilities in China's earthquake early warning ecosystem, where unauthorized entities can bypass official channels to issue potentially life-threatening false alerts to millions of users. The case underscores the importance of centralized, verified information dissemination during natural disasters, as panic-inducing false warnings can lead to unnecessary evacuations, traffic accidents, and erosion of public trust in emergency notification systems. Moreover, the dispute between the research institute and official earthquake authorities highlights the need for clearer regulatory frameworks governing third-party access to public safety infrastructure.
