五、城市防震减灾的两个工作基础——地震监测预报和震害预测 根据古今中外许多大地震震例,特别是从近年来许多城市直下型破坏性地震的震例来看,想要取得防震减灾的实效,单靠地震预报或构筑物的抗震设防是不够的,起码在目前阶段是这样。根据我国“以预防为主,防救结合”的防震减灾方针,我们防震减灾工作的内容至少要包括地震的监测预报、震害防御、地震应急和震后紧急救援及灾区重建等四个基本环节。应当 V. Two Working Bases for Urban Earthquake Preparedness and Disaster Mitigation——Earthquake Monitoring and Prediction and Earthquake Damage Prediction According to the earthquake cases of many major earthquakes in ancient and modern times, especially from the earthquake cases of many direct destructive earthquakes in recent years, we would like to obtain earthquake proof. The effectiveness of disaster reduction depends on earthquake prediction or seismic fortification of structures is not enough, at least at this stage. According to the principle of “prevention-oriented, prevention-rescue-combined” earthquake prevention and reduction in China, the contents of our earthquake prevention and reduction work should at least include four basic links: earthquake monitoring and prediction, earthquake damage prevention, earthquake emergency and post-earthquake emergency rescue, and reconstruction of the disaster area. . should
