In this case, several weeks and 200 mm of precipitation were needed to cause landslide reactivation. A similar approach is reported by Brand et al. (1988) for Hong Kong, who found that if the 24-hour antecedent rainfall exceeded 200 mm then the rainfall threshold for a large landslide event was 70 mm·h −1. Finally, Caine (1980) established a ...
A landslide in which the sliding surface is located within the soil mantle or weathered bedrock (typically to a depth from few decimeters to some meters) is called a shallow landslide. Debris slides and debris flows are usually shallow. Shallow landslides can often happen in areas that have slopes with high permeable soils on top of low ...
A landslide, also called a landslip, [10] is a relatively rapid movement of a large mass of earth and rocks down a hill or a mountainside. Landslides can be further classified by the importance of water in the mass wasting process. In a narrow sense, landslides are rapid movement of large amounts of relatively dry debris down moderate to steep ...
Mudslides and landslides can cause extensive property damage and even be fatal. Here's a look at the causes of and differences between them. Most common causes of mudslides and landslides [Video]
The majority of naturally occurring landslides happen in isolated locations, posing a threat to ongoing development. [1] Aerial photographs can be used to find all current and historical landslides in and around the research region to gauge vulnerability to future landslides. [1] A landslide scar refers to the local area disrupted by the ...
Sudden slumps usually occur after earthquakes or heavy continuing rains, and can stabilize within a few hours. Most slumps develop over comparatively longer periods, taking months or years to reach stability. An example of a slow-moving slump is the Swift Creek Landslide, a deep-seated rotational slump located on Sumas Mountain, Washington.
Articles relating to landslides, several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, shallow or deep-seated slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or ...
United States border patrol agents in Washington seized more than $1.1 million worth of cocaine near the Canadian border last week. Agents assigned to the Blaine Sector in Lynden, Washington found ...
