在大地震发生几秒后发出警报,抢在地震波到达之前为人们留出可能的逃生时间,这是地震预警希望做到的。近年来,我国地震预警研究可谓遍地开花,然而,所有的研究无一例外,均在推广应用上碰了壁。5月12日是全国防灾减灾日,人们对于汶川地震那场灾难的记忆也再次被唤醒。就在此前几天,首都圈地震预警系统投入使用,该系统能够在地震后7秒内迅速发出地震预警警报,将为首都圈民众和地铁、化工等重大工程提供地震预警服务。首都圈预警系统的负责人是成都高新减灾研究所所长王暾。5月
A few seconds after the earthquake, an alert was issued to grab the probable escape time before the arrival of the seismic wave, which the earthquake warning hopes to achieve. In recent years, the research on earthquake early warning in our country can be said to flourish everywhere. However, all the researches are all on the walls of popularization and application. May 12 is the National Day for Disaster Prevention and Mitigation, and people are once again awakened to the memory of the disaster that struck Wenchuan Earthquake. Just a few days ago, the metropolitan area earthquake early warning system was put into operation. The system can quickly send an earthquake early warning alert within 7 seconds after the earthquake and will provide earthquake early warning services to the people in the metropolitan area and major projects such as the subway and chemical industry. The head of the metropolitan area early warning system is Wang 暾, director of Chengdu Institute of High-tech Disaster Reduction. May
