余震活动持续时间的不均匀应力速率模型

A Nonuniform Stress Rate Model of Aftershock Duration

基于在地震重复发生周期内震源区断层面上不均匀应力速率条件下，对地震发生的概率分析，获得地震发生后余震活动持续时间与地震重复周期或应力降成正比的理论结果。它与观测结论是一致的。

Based on a probabilistic analysis of earthquake reccurrence under the condition of nonuniform stress rate on source fault during the earthquake reccurrence period, the conclusions are that aftershock duration might be proportional to the reccurrence period (or stress drop ) of the mainshock, and it is consistent with observation data.
