震中烈度是震源附近宏观破坏最为严重区域的地震烈度,快速判定其大小对指导抗震救灾具有重要意义。搜集整理了我国大陆地区1966-2014年期间的175次震级在5.0级以上的地震事件,回归得到了震中烈度与震级和震源深度的统计经验关系。与以前的研究结果相比,所选取的基础数据数量更大,而且均是近50 a来的地震事件,地震参数信息更为准确和统一。研究结果可用来快速判定震中烈度的大小。
The intensity of the epicenter is the intensity of the earthquake with the most serious macro damage near the source. It is of great significance to quickly determine its magnitude to guide the earthquake relief work. A total of 175 earthquakes above magnitude 5.0 were collected during the period from 1966 to 2014 in mainland China. The empirical correlations between epicenter intensity and magnitude and focal depth were obtained by regression. Compared with the previous results, the number of selected basic data is larger and both are the seismogenic events in recent 50 years. The seismic parameter information is more accurate and uniform. The results of the study can be used to quickly determine the magnitude of the epicenter intensity.
