2D Resistivity Imaging Investigation of Long Point, Katy-Hockley, Tomball and Pearland Faults Introduction 2D Resistivity Imaging Investigation of Long Point, Katy-Hockley, Tomball and Pearland Faults, Houston, Texas - 2012

Geological, Geophysics, Environmental & Geotechical Engineering

Saribudak reported in 2012 that active growth faults cutting the land surface in the Gulf Coast area may represent a serious geo-hazard. Although the average movement of these faults is only a few inches per decade, the potential exists for structural damage to highways, industrial buildings, residential houses and railroads that cross these features.

The author has conducted 2D resistivity imaging surveys at two sites over two known locations of Long Point fault (Moorehead at Westview, and NW section of east Beltway 8 and I-10 intersections) in the southwest part of Houston, Texas; Katy-Hockley and Tomball faults are located in the northwest part, and the Pearland fault in the southeast part of the Houston area.

Results of 2D resistivity surveys on four faults in the Houston area have identified resistivity anomalies that can be used to locate the faults, determine the extent of near-surface deformation, and provide geological information.
