Many ongoing natural processes and human activities can displace the ground under our homes and communities at considerable economic cost and human suffering. The best solutions to these unstable ground problems are based on awareness of where and how they occur. Living with Unstable Ground, written by Dr. Thomas L. Holzer of the U.S. Geological Survey, explains how soil types, slope movements, catastrophic collapses, and regional ground movement affect communities and how to mitigate these disruptive, dangerous, and costly problems.
