对大陆型地震的长期危险性研究,七十年代有了新的途径,即借助于对活动地震构造带(区)的定量化研究,将地质学和地震学的方法结合起来,利用历史地震、古地震等资料计算地震带(区)或断裂带的地震重复周期,并以此综合评定其潜在的地震危险性,取得了一定的成效。本文即基于这一思路,根据历史地震资料,结合地质学研究成果,利用文献和文献的方法,具体计算了南黄海海域(32°—34.5°N,120°.5—123°.5E)M_s≥5级的地震平均重复周期。并以此评定该区域的地震趋势,这将有利用对该区的地震活动监视和沿海资源及滩涂的开发。
In the 1970s, a new approach was taken to study the long-term danger of continental-type earthquakes. By means of quantitative study of active seismic zones (zones), the methods of geology and seismology were combined to make use of historical earthquakes, Ancient earthquakes and other data to calculate the earthquake zone (zone) or fault zone seismic repetition cycle, and comprehensive assessment of its potential seismic hazard and achieved some results. Based on this idea, based on the historical seismic data and the research results of geology, this paper uses the literature and literature methods to calculate the M_s of the South Yellow Sea (32 ° -34.5 ° N, 120 ° .5-123 ° .5E) Earthquakes ≥5 repeat cycles. And to assess the seismic trends in the area, which will make use of the monitoring of seismic activity in the area and the exploitation of coastal resources and beaches.
