Abstract

More than 300 active gravity-driven faults intersect the Earth's surface in the Houston metropolitan area on the northern edge of the Gulf of Mexico Basin. These surface faults have caused damage to roads, pipelines, and buildings. Lidar has proved an effective tool for mapping fault scarps and topographic changes related to potential faults. Near-surface techniques such as seismic and GPR have proven effective in determining whether topographic features that resemble scarps are faults or related to some other natural or anthropogenic surface features.
