LAND SUBSIDENCE AND EARTH FISSURING IN CENTRAL ARIZONA
Land subsidence and earth fissures in central Arizona are geologic hazards being monitored by aerial photography. Ground-water level declines of 200ft - 400ft (61m - 122m) in the past 30 yr have caused subsidence of 2ft - 12ft (0.6m - 3.7m) in several areas totaling hundreds of square miles. Earth fissures -- tensional cracks -- appear near the margins of these areas. Subsidence is continuing in these areas and appearing in others. The number of fissures mapped is also increasing. Both subsidence and fissures, once confined to the rural agricultural areas, are now found in suburban and even urban locations. Both have affected highways, railroads, and pipelines.
