本文较详细地介绍了近三十年来我国地震地质工作者对著名的四川鲜水河断裂带所进行的大量的、多手段的综合考察和监测预报分析研究的基本概况。从该断裂带的构造运动及其力学性质、强震 P 波初动解、地震活动盛衰交替性、强震复发周期短、与附近地震带地震活动有相关性等诸方面,归纳了一些多年来研究分析的初步认识。并根据许多人建议应在鲜水河断裂带建立地震监测和预报研究的试验场,而为此提出该断裂带所具有的三个有利条件。
This paper presents in more detail the massive survey and comprehensive analysis of the Xianchuanhe fault zone in Sichuan Province conducted by the Chinese earthquake geologists in recent thirty years. From the tectonic movement and mechanical properties of the fault zone, the initial P wave of strong earthquakes, the alternation of the seismogenic activity, the short period of strong earthquakes and the correlation with the seismic activity of nearby seismic zones, Research analysis of the initial understanding. Based on the suggestion of many people that a test ground for seismic monitoring and prediction research should be established in the Xianshuihe fault zone, three favorable conditions for the fault zone are proposed.
