Reexamination of geodetic data has shown that aseismic slip occurred on or near the San Andreas fault in the period of about 20 years after 1906. The inferred displacements are comparable to but at greater depths than the sudden slip that occurred at the time of the earthquake. The postseismic slip is constrained only between late 1906 and 1925, and data are insufficient to determine the movements, if any, below about 20 kilometers on the fault. Two independent observations also indicate stubstantial anomalous crustal deformation away from the fault at least 30 years before the earthquake.
重新审查大地测量数据表明，1906 年之后的大约 20 年期间，圣安德烈亚斯断层发生了地震滑动或在其附近发生了地震滑动。推断出的位移与地震时发生的突然滑动相当，但深度更大。余震滑动仅受到限制，时间从 1906 年末到 1925 年，而且数据不足以确定断层下方约 20 公里处是否有任何运动。两项独立的观测结果也表明，在地震发生至少 30 年前，远离断层的地壳发生了大量异常变形。
