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 ...
Sleet warning WSW (alt.: heavy sleet warning) – Heavy sleet accumulations of 1 to 2 inches (2.5 to 5.1 cm) or more, which may cause significant disruptions to travel or utilities, are imminent or expected to occur within 12 hours. Discontinued beginning with the 2008-2009 winter storm season and replaced by the winter storm warning for heavy ...
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 ...
Shipley said the landslide may have been triggered by "significant snowfall" in the area recently. "Water and snowmelt seeps into the soil and rock (and) combined with the natural freeze/thaw ...
The map, a product of advanced data analysis and high-resolution elevation data, shows that roughly 44% of U.S. territory could experience landslide activity. For millions of Americans, their ...
landslide landspout A type of tornado emerging from a parent cloud that does not contain a pre-existing mid-level mesocyclone or other rotation. Landspouts share a development process and resemblance with waterspouts. They are generally smaller and weaker than supercell tornadoes and are rarely detected by Doppler weather radar.
Rainfall is one of the most common triggers of landslides and scientists warn the slides could become more frequent as the climate crisis fuels heavier rainfall and more powerful storms.
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 ...
