An emergency population warning is a method where by local, regional, or national authorities can contact members of the public to warn them of an impending emergency. These warnings may be necessary for a number of reasons, including:
- Weather emergencies such as tornadoes, hurricanes, and ice storms.
- Geological disasters such as earthquakes, landslides, volcanic eruptions, and tsunamis.
- Industrial disasters such as the release of toxic gas or contamination of river water.
- Radiological disasters such as a nuclear plant disaster.
