LANDSLIDE HAZARDS

Landslides occur in most regions containing slopes, and create LANDSLIDE HAZARDS to roads, utility lines, and buildings. Most landslides move slowly enough that people are not directly threatened, but some are so rapid people are trapped in their houses. Therefore, analyzing landslide hazards requires knowing these parameters:

To locate and map landslides GEO-HAZ uses stereo aerial photography and other remote sensing platforms that emphasize their irregular topography (e.g., LIDAR).

GEO-HAZ typically analyses landslide stability by computer programs using the limit equilibrium approach. To support such analyses we drill boreholes through the landslide to measure thickness, material strengths, and groundwater pore pressures. The lower the current stability, the higher the chance of future movement.

Since 1991 GEO-HAZ has specialized in mapping and analyzing LANDSLIDE HAZARDS, and recommending mitigation plans against their effects. In the past few years the demand for such hazard analyses has increased, due to new energy infrastructure projects such as conventional power plants, nuclear power plants, nuclear waste repositories, renewable power plants, dams, pipelines, and transmission lines.
