The bedrock and surficial geologic map of the Satan Butte and Greasewood 7.5' quadrangles was completed in a cooperative effort of the U.S. Geological Survey (USGS) and the Navajo Nation to provide regional geologic information for management and planning ...

<p>Natural gases are a potential hazard in construction of underground excavations. Encountering with gases usually result in costly delays. Gases occur in a wide variety of geological conditions, so predict the occurrence of potentially hazardous concentrations ...

Yosemite Valley has experienced over 600 rock falls since 1850, but determining the exact source areas, volumes, and failure mechanisms for these rock falls has previously been difficult because of a lack of comprehensive imagery of the cliff faces. We obtained ...

Since its inception in 1835, the British Geological Survey (BGS) has been responsible for providing much of the earth science related information that is required by government, the public and institutions. These requirements have evolved over time, with emphasis ...

Canadian railways are exposed to various ground hazards because of the diverse geographic regions of the country. Keegan (2007) analysed these hazards and proposed hazard scenarios to evaluate the influence of these hazards on railway operations. Process modelling ...

In the epicentral areas of major recent earthquakes, landslide density scales with peak ground acceleration. Topographic site effects on seismic waves are known to cause important gradients in ground acceleration in individual mountain ridges. Using landslide ...

These guidelines primarily aim to assist planners (and other interested parties) in determining whether planning documents and resource consent applications at regional and district levels incorporate appropriate information on landslide and slope instability ...

By means of a literature search, technical interviews, and field inventory, I have located 254 large (at least 10 m high) dams worldwide that directly interact with landslides; that is, they have been built on pre-existing landslides or have been subjected ...

Landslides from massive rock slope failure (MRSF) are a major geological hazard in many parts of the world. Hazard assessment is made difficult by a variety of complex initial failure processes and unpredictable post-failure behaviour, which includes transformation ...

Risk analysis and risk evaluation are increasingly used tools for mitigating geohazards. It is commonly accepted that risk is basically a function of likelihood and consequence. However, the quantification of the likelihood of a geohazard occurring, as well ...
