Hazard maps are created and used in conjunction with several natural disasters. [1] Different hazard maps have different uses. For instance, the hazard map created by the Rizal Geological Survey is used by Rizalian insurance agencies in order to properly adjust insurance for people living in hazardous areas. [2]
Water management (groundwater drawdown and water leakage) Land use (e.g. construction of roads, houses etc.) Mining and quarrying; Vibration; Occasionally, even after detailed investigations, no trigger can be determined - this was the case in the large Aoraki / Mount Cook landslide in New Zealand 1991. It is unclear as to whether the lack of 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 ...
Landslides occur around the world and have helped shape the Earth as we know it. The landslide that destroyed a rural neighborhood and claimed 43 lives in Oso, northeast of Seattle, 10 years ago ...
In the wake of Hurricane Helene, more than 2,000 landslides displaced families in western North Carolina. They are waiting to find out if rebuilding is even possible or safe.
This type of measure is used in cases of smaller landslides. The effectiveness of micropiles is linked to the insertion of micropiles over the entire landslide area. In the case of rotational landslides in soft clay, the piles contribute to increasing the resisting moment by friction on the upper part of the pile shaft found in the landslide.
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.
Köfelsite (impactite or frictionite), Köfels Structure, Austria. The sample is 4.1 cm (1.6 in) wide. The amount of energy in a sturzstrom is much higher than in a typical landslide. Once moving, it can ride over nearly any terrain and will cover much more horizontal ground than downward-sloped ground.
