到目前为止,虽然准确地预报在何时何地发生地震还是不可能的,但是估计潜在地震对城市造成的影响可能有助于防震,从而减少地震对城市造成的破坏。根据全国地震研究委员会的研究小组的一份新报告,由地震学家、工程师和紧急事务管理官员进行的震前研究,是“在一些有严重地震威胁但未引起重视的地区开始实施有效计划的一项重要措施。”这些“估计地震损失”的研究,是对某个特定地区的假设地震的影响的预测。万一发生地震,这些研究还提供对伤亡、财产损失、工业能力和应急设施损失的估计,以及对无家可归者和从事防震的社团经济影响的估计。根据1983年联邦紧急事务管理局的一份报
So far, it has not been possible to predict accurately when and where an earthquake will occur, but estimating the impact of a potential earthquake on the city may help prevent earthquakes and thus reduce the damage caused by the earthquake to the city. A pre-earthquake study by seismologists, engineers, and emergency management officials, according to a new report by the National Seismic Research Group’s research group, was “to start effective planning in areas that have not been valued by serious seismic threats An important measure. ”These“ estimated earthquake losses ”studies are predictions of the effects of hypothetical earthquakes in a particular area. In the event of an earthquake, these studies also provide estimates of casualties, property damage, loss of industrial capacity and emergency facilities, and estimates of the economic impact on the homeless and earthquake-resistant communities.
