A total volume of 3,500 km 3 (840 cu mi) debris was involved; comparable to a 34 m (112 ft) thick area the size of Iceland. The landslide is thought to be among the largest in history. [citation needed] Landslide which moved Heart Mountain to its current location, the largest continental landslide discovered so far. In the 48 million years ...
The difference between these two concepts is subtle but important. The landslide causes are the reasons that a landslide occurred in that location and at that time and may be considered to be factors that made the slope vulnerable to failure, that predispose the slope to becoming unstable. The trigger is the single event that finally initiated ...
Landslides can be triggered by many, sometimes concomitant causes. In addition to shallow erosion or reduction of shear strength caused by seasonal rainfall, landslides may be triggered by anthropic activities, such as adding excessive weight above the slope, digging at mid-slope or at the foot of the slope. Often, individual phenomena join to ...
Using laser scans and GPS cameras, accurate down to one inch, the U.S. Geological Survey has so far mapped more than 600 landslides caused by Hurricane Helene.
It estimates the average annual soil loss A on a plot-sized area as: [98] A = RKLSCP. where R is the rainfall erosivity factor, [99] [100] K is the soil erodibility factor, [101] L and S are topographic factors [102] representing length and slope, [103] C is the cover and management factor [104] and P is the support practices factor.

Historical maps of the ancient landslide ... recent measurements from across the landslide area — from July 1 to Aug. 1 — showed the overall rate of land movement had decelerated, by about 1% ...
Huge landslide at La Conchita, 1995. A geologic hazard or geohazard is an adverse geologic condition capable of causing widespread damage or loss of property and life. [1] These hazards are geological and environmental conditions and involve long-term or short-term geological processes.
Illinois' ecology is in a land area of 56,400 square miles (146,000 km 2); the state is 385 miles (620 km) long and 218 miles (351 km) wide and is located between latitude: 36.9540° to 42.4951° N, and longitude: 87.3840° to 91.4244° W, [1] with primarily a humid continental climate.
