The State of California Department of Conservation produces regulatory maps showing locations where the hazard from earthquake-triggered landslides must be evaluated prior to specific types of land-use development in accordance with provisions of Public Resources Code, Section 2690 et seq. (Seismic Hazards Mapping Act). These maps and related ...
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 ...
Since its founding in 1991, [2] GeoHazards International has worked in more than 20 different countries around the world to develop and deploy preventative solutions that are known to save lives in the face of natural disasters such as earthquakes, tsunamis, landslides, and impacts from climate change.
“Basic physics says that once a body is in motion, it wants to stay in motion,” said Jonathan Godt, the landslides hazards program coordinator at the U.S. Geological Service. The threat to ...

"Due to the continued movement of the landslide, the ground movement features have continued to enlarge, expand, widen, or grow depending on the type of feature and location." And that means the ...
The application of vegetation to increase the slope stability against erosion and landslide is a form of bioengineering that is widely used in areas where the landslide depth is shallow. Vegetation increases the stability of the slope mechanically, by reinforcing the soils through plant roots, which stabilize the upper part of the soil.
An ancient complex of landslides under the Portuguese Bend Reserve, located within the larger Palos Verdes Nature Preserve, was activated in 1956, which halted all housing development in the area.
