景泰地震台短周期地震仪记录的几种异常波形特征与景泰6.2级地震的关系

本文研究了景泰地震台记录到的几种异常地震波形的形态特征及随时间分布特征,采用测震学的方法和数理统计的方法,对各个阶段的异常波形出现的数量、类型和振幅进行了定量分析,发现在1990年10月20日景泰6.2级地震前,异常波形数量明显地呈平静一密集交替出现的现象;临震前各种异常波形的数量增多,振幅增大,异常持续时间增长,震后异常波形很快衰减并消失.与其他前兆对比,可以认为异常波形的出现可能与景泰地震的孕育过程有关,根据该类波形的变化特征有可能对地震作出预报.

地电短临前兆产生机理及一种新的短临预报方法（谐振预报法）

研究了地电短临震兆机理，在此基础上给出了引潮力触发地电短临前兆模式。据此从理论上分析了地电临震震兆特征，并以唐山７．８级大震为例，从实际观测中检出具有此模式特征的震兆（具有起潮力特征），从而验证了所提模式理论的客观存在的可能性。最后给出与此有关的地电短临预报方法。即，根据脆性岩石失稳的相对刚度比较准则，定义部分岩体刚度λ＝０的状态为临震阶段，分析λ＝０时起潮力引起位移的特征和规律，得出原地监测岩体刚度是否为零（进入临震阶段）的方法。因为在弹性阶段，λ为较大正值，微小的起潮力只引起微小的位移，此时的电响应甚小，通常检测不到；但随着构造力的积累，介质进入临震阶段，此时同样微小的起潮力却可引起甚大的位移（λ＝０时，位移为无穷大），从而产生可检测的电响应。由于这种电响应具有与起潮力相同的周期，故可把临震电响应同各种干扰区分开，判定为临震前兆，从而建立了地电临震前兆起潮力触发模式，并可给出相应的短临预报方法。对１９７６年唐山７．８级强震前后震中周围地电阻率及大地电场实测资料进行谱分析，发现仅在主震前二个月至半月内，两种不同物理本质的电响应分别出现与起潮力ＭＳ波与ＭＳｆ波周期相同的异常变化。这是对所提临震前兆模式和预报     

Morphological characteristics of the earthquake surface ruptures on Awaji Island, associated with the 1995 Southern Hyogo Prefecture Earthquake

Abstract The earthquake surface ruptures on the northern side of Awaji Island accompanying the 1995 Southern Hyogo Prefecture Earthquake in Japan consist of three earthquake surface rupture zones called the Nojima, Matsuho, and Kusumoto Earthquake Surface Rupture Zones. The Nojima Earthquake Surface Rupture Zone is - 18 km long and was formed from Awaji-cho at the northern end of Awaji Island to Ichinomiya-cho. It occurred along the pre-existing Nojima geological fault in the northern segment and as a new fault in the southern segment. The northern segment of the Nojima Earthquake Surface Rupture Zone is composed of some subparallel shear faults showing a right-step en echelon form and many extensional cracks showing a left-step en echelon form. The southern segment consists of some discontinuous surface ruptures which are concentrated in a narrow zone a few tens of meters in width. This surface rupture zone shows a general trend striking north 30°-60° east, and dipping 75°-85° east. The deformational topographies and striations on the fault plane generated during the co-seismic displacement show that the Nojima Earthquake Surface Rupture Zone is a right-lateral strike-slip fault with some reverse component. Displacements measured at many of the outcrops are generally 100-200 em horizontally and 50-100 em vertically in the northern segment and a few em to 20 em both horizontally and vertically in the southern segment. The largest displacements are 180 em horizontally, 130 em vertically, and 215 em in netslip measured at the Hirabayashi fault scarp. The Matsuho Earthquake Surface Rupture Zone striking north 40°-60° west was also found along the coastline trending northwest-southeast in Awaji-cho for ～1 km at the northern end of Awaji Island. The Kusumoto Earthquake Surface Rupture Zone occurred along the pre-existing Kusumoto geological fault for ～ 1.5 km near the northeastern coastline, generally striking north 35°-60° east, dipping 60°-70° west. From the morphological and geomorphological characteristics, the Nojima Earthquake Surface Rupture Zone can be divided into four segments which form a right-step en echelon formation. The geological and geomorphological evidence and the aftershock epicenter distributions show clearly that the distributions and geometry of these four segments are controlled by the pre-existing geological structures.     

中国东部特殊地震带研究
