利用GPS连续站资料研究地壳运动与地震的关系
|
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.
