许多重要的见解都包含在对 1906 年旧金山地震地表破裂的详细观察中，在这次地震中，地表断层与管道、土堤和建筑物相互作用。从 1906 年断裂中汲取的教训，结合最近地震的平行和新见解，说明了各种地质条件如何改变断层的表面表现，以及表面断层断裂如何与工程系统相互作用。地质和工程程序可用于评估与地表断层相关的危害并开发合理的设计。使用说明性示例来演示如何解决与地表断层破裂相关的危险。有效的设计措施包括建造填土以部分吸收下面的地面运动；将地基与底层地面运动隔离；设计坚固、有延展性的基础，可以适应一定的变形，而不影响结构的功能。
Many important insights are embedded in the detailed observations of surface rupture of the 1906 San Francisco earthquake, during which surface faulting interacted with pipelines, earth embankments, and buildings. Lessons gleaned from the 1906 rupture, combined with parallel and new insights from recent earthquakes, illustrate how various geologic conditions alter the surface expression of faulting and how surface fault rupture interacts with engineered systems. Geologic and engineering procedures can be employed to evaluate the hazards associated with surface faulting and to develop sound designs. Illustrative examples are used to demonstrate how the hazards associated with surface fault rupture can be addressed. Effective design measures include constructing earth fills to partially absorb underlying ground movements; isolating foundations from the underlying ground movements; and designing strong, ductile foundations that can accommodate some deformation without compromising the functionality of the structure.
