A profile of measurements of shear stress perpendicular to the San Andreas fault near Palmdale, California, shows a marked increase in stress with distance from the fault. The pattern suggests that shear stress on the fault increases slowly with depth and reaches a value on the order of the average stress released during earthquakes. This result has important implications for both long- and shortterm prediction of large earthquakes.
对加利福尼亚州帕尔姆代尔附近圣安德烈亚斯断层垂直方向的剪应力测量结果显示，应力随距断层距离的增加而显著增大。这种模式表明，断层上的剪应力随深度缓慢增加，并达到与地震期间释放的平均应力相当的量级。这一结果对大地震的长期和短期预测都具有重要意义。
