形变数字化资料对邢台地区地震前兆反应的研究

THE RESPONSE OF DIGITAL CRUSTAL DEFORMATION DATA TO THE EARTHQUAKES IN XINGTAI AREA

    摘要
  • 摘要: 使用张家口、怀来、赤城、宽城、易县和涉县6个台站共计43个测项的数字化资料,针对2002~2005年邢台地区发生的3个M>4级的中强地震,进行了地震前兆和同震反应研究。发现我省数字化形变资料对3次邢台4级以上地震的形变前兆反应主要是以应变为主,包括体应变和线应变,并且异常形态以固体潮畸变和抖动为主。同震反应比较明显,主要以同震阶跃为主。

     

    Abstract: The coseismic response of digital data,which observed by 43 precursor items in Zhangjiakou,Huailai,Chicheng,Kuancheng,Yixian and Shexian seismostation,to the 3 over 4 magnitude earthquakes occurred in Xingtai area from 2002 to 2005 is studied.The results show that the seismic response concentrated in strain data,including body strain and linear strain.The anomaly shape mainly is tidal aberrance and dithering.Coseismic response is clear and mainly showed in jump shape.
