'Death Map' Plots Where Most Fatalities Could Occur

This probably will not come as a shock to many living in the South along the Atlantic and Gulf Coasts, but those residents have a greater likelihood of dying from a natural hazard compared to residents in the Great Lakes area and the urbanized Northeast.

Those findings come from a new map plotting deaths from forces of nature, revealing where Mother Nature is most likely to kill you.

And while intense hurricanes and tornadoes steal headlines for their intense winds and overall destruction, the new map reports what other previous studies have found, that everyday hazards, such as severe winter and summer weather, and heat account for the majority of natural hazard deaths in the United States.

"This work will enable research and emergency management practitioners to examine hazard deaths through a geographic lens," said researcher Susan Cutter of the University of South Carolina, Columbia. "Using this as a tool to identify areas with higher than average hazard deaths can justify allocation of resources to these areas with the goal of reducing loss of life."

Cutter and Kevin Borden, also of the University of South Carolina, Columbia, analyzed nationwide data from 1970 to 2004.

Along with the South having high mortality from natural hazards, other risky areas included the northern Great Plains region where heat and drought were the biggest killers and the Rocky Mountain region (Montana, Idaho, Wyoming, Colorado, Utah and New Mexico) with winter weather and floods as top killers. The south-central United States is also a dangerous area, with floods and tornadoes posing the greatest threats.

Cutter and Borden discovered that of the natural hazards, some were deadlier than others over the years.

"It is the chronic hazards like severe summer weather and severe winter weather and heat that are contributing the majority of the hazard fatalities, not fatalities associated with things like earthquakes or hurricanes," Cutter told LiveScience. She added that people and officials tend to be more prepared for big hurricanes and tornadoes, which could partly explain the lower mortality from these storms compared with everyday occurrences.

The natural hazards research, which will be detailed in a forthcoming issue of the International Journal of Health Geographics, was supported by the U.S. Department of Homeland Security through the National Consortium for the Study of Terrorism and Responses to Terrorism.
