Increased reporting
of tornadoes is also thought to have been facilitated by the combination of
improvements in NWS storm detection technology (e.g., Next Generation
Weather Radar or NEXRAD) and the development of a national system of NWS
volunteer weather spotters.
People are injured or killed by tornadoes when they are struck by
energized debris or when their bodies are thrown into stationary objects.
Head injuries have been observed to be the most likely cause of death among
tornado victims (16-17). For every person who dies as a result of a
tornado, an estimated 20 people are injured (8). Immediate public
health relief needs of survivors include medical care, shelter, and
assistance in collecting dispersed property and disposing of debris.
