According to a report by China News Network, the earthquake early warning system jointly constructed by Zhaotong Earthquake Preparedness Reduction and Disaster Reduction Bureau and Chengdu Institute of High and New Technology for Disaster Reduction successfully warned on the day of the earthquake and provided early warnings of 10 seconds and 57 seconds respectively to Ludian County and Kunming, Zhaotong City. “Earthquake Warning ” reduces the number of deaths and property losses, but also to protect the personal safety of rescue workers after the earthquake. Statistics show that when the earthquake occurs, if the warning time is 3 seconds, the casualty rate will drop by 14%. If it is 10 seconds, the casualty rate will drop by 39%.
