A comprehensive review of Texas earthquakes from 1847 to 1986 has revealed 106 earthquakes of magnitude 3 or greater; of these, 24 are earthquakes for which reports of damage are available, and 1 was responsible for a human fatality. All known reports on Texas seismicity are incorporated in this circular, including original "felt" (eyewitness) reports from contemporary newspapers and other sources.

The purposes of this study were (1) to quantify recent (1974 to 1982) movement of Texas shorelines and vegetation lines by analysis of aerial photographs; (2) to place this movement in historical (pre-1974) context; and (3) to examine the influence of environmental variables such as storms, sea level, subsidence, and sediment supply on the movement of coastal boundaries.
