The ATC-AGI report, Living with Unstable Ground, was produced by the American Geological Institute (AGI), in cooperation with Applied Technology Council with support from the ATC Henry J. Degenkolb Memorial Endowment Fund, the Association of Environmental & Engineering Geologists, and the U.S. Geological Survey. (Published 2009, 64 pages)ææ
ABSTRACT: This report is a practical guide written to increase awareness and understanding of how structures can be built safely in areas with unstable ground and what society can do to reduce the impact of unstable ground.
Living with Unstable Ground describes and discusses the causes and occurrence of unstable ground largely from a geoscience perspective. Topics addressed by the document include:
- problem soils,
- slope movement,
- catastrophic collapse,
- regional ground movement, and
- guidelines for living with unstable ground.
The document notes that whether ground displacements are large and catastrophic or small and slow, their cumulative impact during the lifetimes of humans or civilizations may be large and destructive. Parts of every state in the United States are affected by these instabilities of the ground. As the demand for land grows and humans increasingly modify their environment, more and more people will be exposed to these instabilities and suffer the consequences.
