TAIPEI (TVBS News) — The Central Weather Administration (CWA, 中央氣象署) announced on Friday (Aug. 30) a new earthquake early warning system starting Sept. 1, to enhance public preparedness for major quakes. This initiative aims to provide timely alerts for earthquakes estimated to be magnitude 6.5 or higher.
The criteria for the "Earthquake Alert" include issuing warnings for estimated magnitude 5.0 quakes with an intensity of 4 or higher in affected counties or for quakes of magnitude 6.5 and above with an intensity of 3 or higher.
The CWA will also focus on enhancing the precision of its early warning systems and promoting earthquake disaster education.
The "Earthquake Alert" service, a part of the CWA's "Earthquake Early Warning," (強震即時警報) uses cell broadcast technology to send warnings within seconds to tens of seconds after a major quake. This critical window allows people to take immediate safety measures, such as seeking cover indoors or stopping vehicles safely.
Recognizing that larger quakes often involve prolonged shaking and strong low-frequency energy, especially felt in high-rise buildings, the CWA has updated its criteria for issuing alerts. This adjustment aims to cover a broader range of earthquake scenarios, improving the accuracy and scope of warnings.
The CWA emphasized that through technological advancements and public cooperation, they hope to effectively reduce earthquake disaster risks and contribute to Taiwan's safety and resilience.
