The April to June 1992 Landers earthquake sequence in southern California modified the state of stress along nearby segments of the San Andreas fault, causing a 50-kilometer segment of the fault to move significantly closer to failure where it passes through a compressional bend near San Gorgonio Pass. The decrease in compressive normal stress may also have reduced fluid pressures along that fault segment. As pressures are reequilibrated by diffusion, that fault segment should move closer to failure with time. That fault segment and another to the southeast probably have not ruptured in a great earthquake in about 300 years.
1992 年 4 月至 6 月，南加州兰德斯地震序列改变了圣安德烈亚斯断层附近地段的应力状态，导致断层通过圣戈尔戈尼奥山口附近的一个压缩弯曲段的 50 公里段显著更接近失效。压缩法向正应力的减小也可能降低了该断层段的流体压力。随着压力通过扩散重新达到平衡，该断层段随着时间的推移应该更接近失效。该断层段和东南部的另一个断层段可能在大约 300 年内没有在大地震中发生破裂。
