6月28日的兰德斯地震使圣贝纳迪诺附近的圣安德烈亚斯断层明显接近崩溃，该地点自1812年以来从未发生过大地震。圣贝纳迪诺附近的圣哈辛托断层和棕榈泉东南的圣安德烈亚斯断层的压力也增加了。除非蠕变或中等地震消除这些应力变化，否则圣安德烈亚斯断层南部的下一次大地震可能会提前一到二十年。相比之下，洛杉矶北部圣安德烈亚斯海峡的压力下降，可能会将那里的下一次大地震推迟2到10年。
The 28 June Landers earthquake brought the San Andreas fault significantly closer to failure near San Bernardino, a site that has not sustained a large shock since 1812. Stress also increased on the San Jacinto fault near San Bernardino and on the San Andreas fault southeast of Palm Springs. Unless creep or moderate earthquakes relieve these stress changes, the next great earthquake on the southern San Andreas fault is likely to be advanced by one to two decades. In contrast, stress on the San Andreas north of Los Angeles dropped, potentially delaying the next great earthquake there by 2 to 10 years.
