USGS revises hazards criteria


  • Anonymous


New criteria and terms have been adopted by the U.S. Geological Survey (USGS) for issuing formal statements to government officials and the public about geologic hazards such as earthquakes, volcanic eruptions, and landslides.

The new, two-category system comprises a formal notice, called a hazard warning, and an informal notification for forwarding relevant but less critical information to public officials.
