Natural hazards such as earthquakes, volcanic eruptions, tornadoes, hurricanes,
ice storms, droughts, dust storms and other extreme events threaten different
parts of North America. Floods and forest fires are also priority concerns.
North American governments have put in place many response mechanisms
to prevent and alleviate the harm caused by such factors. Despite strong
regulations governing the handling of hazardous material, occasionally
serious accidents occur, prompting further preventive legislation.
