摘要
本文首先根据地震地质条件和震中分布,将宁夏划分出四个地震带,并绘制了1970—1988年各地震带的地震时—空分布图。然后,分析研究了近18年来地震活动特征和地质构造背景;探讨了本区未来地震危险性等问题。研究结果对地震预报具有一定的意义。
Based on the seismo-geological conditions and epicentral distribution, Ningxia region is divided inta 4 seismic belt and time-space distribution of earthquakes in each belt in 1970-1988 are drawn in this paper. Then the characteristics of seismic activities in the last 18 years and their tectonic setting are studied, and the future earthquake risk in this region is also discussed. The results are of significance in earthquake preduction and forecasting.
