| 摘 要： | 本文对已搜集到的通海地震震后地形变观测资料进行了分析和研究。曲江断裂的震后活动呈指数衰减,和余震衰减规律相似。形变特征以单元滑动频度方式表现出来,与强度(变化幅度) 似无明显关系。断裂滑动和余震的关系表现为如下三种情况:(1)滑动诱发地震;(2)滑动是地震的续发现象;(3)滑动和余震是大震之后断裂活动的共生现象。最后,本文还讨论了动态滑动、静态滑动和稳态滑动特征,及其它们和地震发生之间的关系。

| Abstract: | In this paper, an analytic study has been done on the obtained deformation data after Tonghai earthquake. The activity along Qujiang fault after the event is featuring an index attenuation, which is similar to the aftershock attenuation regulation. The deformation characteristics are shown as a form of unit-sliding frequency, which seems no obvious relation to the strength (the variation amplitude) . The relationship between fault slip and aftershock is indicated as the following three cases. ( 1 ) The slip induces earthquake; ( 2 ) The slip is the continuous stage of the event; and (3) Both slip and aftershock are the accompanying phenomena of fault activity afte a strong event. Lastly, features of dynamic slip, static slip, and stabilized slip and their relations to earthquake occurrences are discussed. |
