摘要
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。
On the basis of mathematical morphology filter, by use of the observations of GPS continuous sites, combining single site, baseline and region variety with earthquake examples, the relation between crustal movement and earthquake is analyzed. And a few probable characteristics reflecting the short-term and impending precursor of earthquake are obtained. Moreover, the earthquake trend reflected by the observation of GPS continuous sites is analyzed.
