河北应变固体潮汐参数及震例研究
The Earthquake Case Studies of the Hebei Solid Tide Parameters
摘要
Abstract
In this paper,based on the deformation observation data of five stations in Hebei,we use VENEDIKOV harmonic analysis method to calculate the Ms> 4.0 earthquake phase and amplitude factor,tidal factor ect.We find that the strain tide factor of five deformation stations has a few weeks to half a year of abnormal period corresponding to the earthquakes.Kuancheng station has the shortest distance (the rarest distance is 350 km,and the nearest distance is 100 km)from the epicenter of these Ms>4.0 earthquakes.Therefore,based on the comprehensive analysis of Hebei strain stations,we use the strain tide factor of Kuancheng station as key data to briefly analyzed the earthquake cases of Hebei from 2005 to 2015.The results show that the corresponding rate of the earthquake and Kuancheng station reaches 60%,the false rate is 40%,the omission rate is only 14%,and the precursory anomaly reliability is higher,which can be used as a reference for precursory anomalies.关键词
