Landslides

A landslide is defined as "the movement of a mass of rock, debris, or earth down a slope" (Cruden, 1991). Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. The term "...

Landslides are a serious geologic hazard common to almost every State in the United States. It is estimated that in the United States they cause in excess of $1 billion in damages and from about 25 to 50 deaths each year. Globally, landslides cause...
Yes, in some cases human activities can be a contributing factor in causing landslides. Many human-caused landslides can be avoided or mitigated. They are commonly a result of building roads and structures without adequate grading of slopes, of poorly...
Every state in the US has a geoscience agency and most have some landslide information. The Association of American State Geologists provides links to the State Geologist for every state. Also, your City and/or County may have a public works engineer and...
The Thistle, Utah, landslide cost in excess of $200 million dollars to fix (1984 dollars – adjusted for inflation this would be more than $400 million in 2010 dollars). The landslide occurred during the spring of 1983, when unseasonably warm weather...
In the United States, it was estimated in 1985 that the total dollar losses from landslides average between $1 billion and $2 billion per year. (As this is an old estimate, a more realistic number is between $2 billion and $4 billion per year, computed...
An average of between 25 and 50 people are killed by landslides each year in the United States. The worldwide death toll per year due to landslides is in the thousands. Most landslide fatalities are from rock fall, debris-flows, or volcanic debris flows...
An advisory is a general statement about the potential of landslide activity in a given region relative to developing rainfall predictions. An advisory may include general statements about rainfall conditions that can lead to debris-flow activity, and...
The U.S. Geological Survey derives its leadership role in landslide hazard-related work from the Disaster Relief Act of 1974 (the Stafford Act). The Director of the USGS has been delegated the responsibility to issue warnings for an earthquake, volcanic...
