聊考断裂南起兰考沿北北东向经东明、菏泽、聊城延至禹城,全长370余公里。断裂倾向北西,倾角一般为40—60度。历史上沿聊考断裂发生的中强地震较多,目前小地震活动也很频繁。自1968年建立区域台网以来,记录该带地震147次。最大4.3级(Ms,下同)。为了研究聊考断裂的活动特征,监视地震活动,山东省地震局分别在东明至菏泽、临清至茌平间设置了水准路线,建立了朝城—莘县—阳谷—朝城环线。黄委会也沿黄河大堤设立了测量路线。上述测线在平面上几乎等距离地分截了聊考断裂(图1)。山东省地震局的测线已经过多期测量。黄委会的测线也曾于1959年至1965年进行二等水准复测工作。无疑这对监视地震活动是有
Talk about the fracture South Lankao test along the north-east east, Heze, Liaocheng Yucheng extension, a total length of 370 kilometers. Northwest fault tendency, dip is generally 40-60 degrees. There are many moderate earthquakes occurred along the fault line in history, and the present earthquakes are also frequent. Since the establishment of the regional network in 1968, the earthquake has been recorded 147 times. Maximum 4.3 (Ms, the same below). In order to study the characteristics of the activity of chatting about faults and to monitor the seismic activity, the Seismological Bureau of Shandong Province set up a standard route between Dongming and Heze and between Linqing and Pingtang respectively, and established Zhaocheng-Shenxian-Shenxian-Yanggu-Zhaocheng Link. The Yellow River Commission also set up a measurement route along the Yellow River Embankment. The above line is almost equidistant in the plane of the chatting fractures (Figure 1). Seismological Bureau of Shandong Province line has been measured over the period. The Yellow Line survey also conducted second-level retest work from 1959 to 1965. There is no doubt that there is to monitor seismic activity
