This research is a continuation of a study to investigate the hypothesis that variations in normal stress across a fault surface are a primary factor controlling stick-slip behavior in laboratory simulations and in earthquakes. The hypothesis has been suggested on the basis of recent work on stick-slip behavior in foam rubber and, if true, will have a major impact on current ideas about rupture nucleation and the characteristics of premonitory slip. The existence of normal vibrations during stick-slip has implications for rupture mechanics, fault behavior, and short-term earthquake prediction. This research is a component of the National Earthquake Hazard Reduction Program.

这项研究是一项研究的延续，旨在调查断层表面正应力的变化是控制实验室模拟和地震中粘滑行为的主要因素的假设。 该假设是根据最近关于泡沫橡胶粘滑行为的研究提出的，如果正确，将对当前有关破裂成核和先兆滑移特征的想法产生重大影响。 粘滑过程中正常振动的存在对破裂力学、断层行为和短期地震预测具有重要意义。 这项研究是国家地震减灾计划的一部分。
