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 ...
Earthquake Hazards Reduction Act of 1977 is a statute formulating a national policy to diminish the perils of earthquakes in the United States.The Act of Congress is a declaration for an earthquake prediction system, national earthquake hazards reduction program, and seismological research studies.
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 ...
“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 ...
The International Consortium on Landslides is a non-governmental organization created in 2002 to promote landslide research, education, and risk evaluation and reduction. It is located in Kyoto, Japan. The organization has consultative status with UNESCO. [1] [2] The ICL's journal is Landslides. It holds regular symposiums, including the World ...
A natural hazard [18] is a natural phenomenon that might have a negative effect on humans and other animals, or the environment. Natural hazard events can be classified into two broad categories: geophysical and biological. [19] Natural hazards can be provoked or affected by anthropogenic processes, e.g. land-use change, drainage and ...
The National Earthquake Hazards Reduction Program (NEHRP) was established in 1977 by the United States Congress as part of the Earthquake Hazards Reduction Act of 1977.The original stated purpose for NEHRP was "to reduce the risks of life and property from future Earthquakes in the United States through the establishment and maintenance of an effective earthquake hazards reduction program."
The Global Assessment Report on Disaster Risk Reduction (GAR) is the United Nation’s biennial global review and analysis of the natural hazards that are affecting humanity. The GAR monitors risk patterns and trends and progress in disaster risk reduction while providing strategic policy guidance to countries and the international community.
