摘要
一、引言 1966年3月22日,河北省邢台地区东汪发生了7.2级地震,距震中80—100公里的井陉—获鹿地区,比距震中较近的栾城地区造成的地震破坏更为严重,烈度异常增高的地区如图1所示。井陉—获鹿地区的地震破坏情况,经仔细调查,有以下四个特点。
The Hingtai earthquake of March 22nd,1966 caused greater damage in the Tsing-sing(井陉)-Huailu(获鹿) area at an epicentral distance of about 90 km than that in the Luancheng(栾城) area which is only about 50km from the epicenter.It is believed that this anomalous distribution of intensity is principally due to the totally reflected S waves from the Mohorovicic discontinuity.In order to identify these waves,the crustal structures of the area were investigated.The effect of the various soil conditions on the surface as well as the fracture zones and others on seismic intensity was also discussed.
