Where can I get a map showing the geologic faults of Texas?
The University of Texas at Austin Walter Geology Library (http://www.lib.utexas.edu/Libs/GEO/geology.html) has a geologic map of Texas which has the major faults on it (but not all the faults). You might also check out the Bureau of Economic Geology: http://www.utexas.edu/research/beg/pub.html Q: Have earthquakes occurred in Houston in historic times? A: No. The closest earthquake occurred on 8 May 1910 near Hempstead, Texas, about 70 km northwest of Houston. This earthquake had a magnitude of about 3.8, and was felt by individuals within about 30 km of Hempstead, but not in Houston. Of course, Houston residents in tall buildings may occasionally feel large very distant earthquakes that occur in Mexico or western Texas. Near Houston there may be examples of faults which are active, but which don’t have any earthquakes. Land in some communities southeast of Houston such as Clear Lake and Dickenson is sinking because water has been pumped out from the ground for many years; this sinking
