宁夏北部及邻区未来几年地震危险性分析

Seismic Hazard Analysis of the North and Adjacent Areas of Ningxia in the Next Few Years

本文对宁夏北部及邻区强震构造危险性和宁夏北部及邻区1950年以来5级以上地震活动特征进行分析,给出了未来强震的区域和活动强度。并通过分析近期该区域存在的广义前震特征和地震活动性参数异常,得到未来宁夏北部及邻区发生6级以上地震的区域,希望本文的研究为该区域的地震预测及跟踪提供参考。

In this paper,the structural risk of strong earthquakes and the characteristics of seismic activities of earthquakes with Ms≥5.0 since 1950 in the North and adjacent areas of Ningxia are analyzed,and the region and activity intensity of strong earthquakes in the future are given.In addition,by analyzing the generalized foreshock characteristics and seismicity parameter anomalies in this region in the near future,the areas of earthquakes with Ms≥6.0 in the Northern Ningxia and adjacent areas in the future can be obtained.It is hoped that this study can provide a reference for earthquake prediction and tracking in this region.
