摘要: 将特征地震之间的次级地震产生的位移看作相对蠕滑速率,推导了相对蠕滑速率的估算公式,进而分析了次级地震对特征地震复发间隔的影响,从而可以更好地与古地震资料对比以得到可靠的特征地震重复间隔。

Abstract: The displacement of all earthquakes with all ranges of magnitude except to the characteristic earthquakes was termed as“relative creep”in this paper. Affection of the relative creep to the recurrence interval of the characteristic earthquakes is analysed. A function is deduced to calculate the relative creep rate. More reliable estimations of seismic interval can be made by comparing the calculated results with the paleoearthquake data.

Key words: Characteristic earthquake, Seismic recurrence interval, Xiaojiang fault, Creep
