【摘要】 主要对1970年以后发生在川滇地区的几次7级以上强震震例进行了分析,研究了强震前水位、水化、地电、地倾斜等前兆手段以及地震学前兆指标的时空演化特征,对比分析了各前兆学科之间的差异性。结果表明,在强震发生前各前兆学科之间存在较好的协调性关系。更多还原

【Abstract】 In this paper, several strong earthquake cases are analyzed, those events occurred in Sichuan and Yunnan region since 1970. We studied the spatiotemporal characteristics of precursors, including geoelectricity, hydrochemistry, water level, ground tilt, discipline precursory indexes of seismology and so on. And at the same time, we comparatively analyzed their different and same characteristics. The studying result shows that there exist harmonious characteristics among all sorts of precursors.更多还原
