WeChat Earthquake Early Warning Adds Shake-Intensity and Location-Update Functions
WeChat has launched two new functions for its earthquake early-warning service: shake-intensity aggregation and location updating. The shake-intensity feature lets users report their felt shaking after an alert, generating a public intensity map through professional algorithms. The location-update function prompts users to refresh their alert subscription location when they move, improving alert targeting. Developed with the China Earthquake Networks Center and National Emergency Broadcasting, the service has now issued alerts for more than 700 earthquakes and surpassed 60 million subscribers.
