Making use of the method of obtaining regional vertical strain rate from regional preciseleveling data and gaining dynamic pattern combining with deformation data on spanningfaults, the regional vertical strain dynamic evolution characteristics of several moderatelystrong earthquakes such as Lijiang (M_s 7.0) and Menyuan (M_s 6.4) earthquakes occurredin crustal deformation monitoring areas located in the western Yunnan and Qilianshan-Hexiregion. Based on the above-mentioned facts, by studying the time-space nonhomogeneity andstrain energy accumulation status, some criteria for judging the medium. and short-termstrong seismic risk regions according to the regional vertical strain rate dynamic informationare proposed.  相似文献

利用1999年以来的GPS连续站资料,引入数学形态滤波法,以单点、基线以及区域变化与震例相结合,分析了地壳水平运动与地震的关系,获得了可能反映地震短临前兆的几个特征。此外,对GPS连续站资料所反映的地震趋势进行了分析。  相似文献
