宁夏地震活动相关性与诱发前震的研究

A PRIMARY STUDY ON THE CORRELATION OF THE EARTHQUAES AND INDUCED FORE-SHOCK IN NINGXIA AND ITS NEIGHBORINGS

  • 摘要: 本文的研究结果表明,宁夏地震与江苏地震、鄂尔多斯块体其他边缘地震以及青藏高原块体的地震话动相关;宁夏境内南部的西(吉)、海(原)、固(原)地震区与北部的银川平原地震区之间的地震,活动也明显相关。这种大尺度的地震活动相关性,都是以一定的地质构造为纽带的。很可能是在同时受力的状态下,一处发震后,促使他处相继发生地震。这反映了地震的块体活动和整个地震带统一活动的特征。同时,诱发前震可能也反映了A、B两次地震的相关活动。

     

    Abstract: The correlation of the earthquakes and induced foreshock in Ningxia a nd its neighboringsregions are described in this paper.The results show that the earthquakes occurred in Ningxia and its neighboring regions are correlated with the eathquakes of given specific regions,such as the boundaries of Ordos block,Jiangsu province,the Qinghai-Xizang plateau block,and Helingeer regionof lnner Mongolia.In addition,the eahth-quakes between the two seismic regions of Yinchuan plain and Xi-Hai-Gu within Ningxia province are of correlation too.The time interval of two correlative earthquakes is about a few days to ten-oddmonths.Induced fore shock of several moderate strong earthquakes of Ningxia and its neigh-boring regions since 1970 are quite clear.But how to distinguish foresho-ckes before big earthquakes is a considerable difficult problem at present.
