About The Resilience Institute

The Resilience Institute is part of WWU Huxley’s College of the Environment. It facilitates scholarship, education, and practice on reducing social and physical vulnerability through sustainable community development, as a way to minimize loss and enhance recovery from disasters in Washington State and its interdependent global communities.

America's "death map" - heat is the big problem


I have been remiss about blogging these days, but this just out on Reuters. It comes from Susan Cutter's work on mapping disaster vulnerability. The work is a first take on creating an American death map. As such, it focuses on threats to human life, showing that heat and severe winter weather are major concerns, even as these culprits often go unnoticed on the national and global scale. A map of American "disaster-caused economic damage" showing what disasters caused the most dollar losses would likely prove to be much different. Together, the two would show what many already know - in the US, changes in codes and emergency response have lowered the loss of life from earthquakes, fires, and to a lesser extent, hurricanes. This has made it possible to put more of our stuff, houses and people, in harms way. Thus, we've lowered the death tolls, but raised the costs of earthquakes, hurricanes, fire and floods. What is left is the silent kills of extreme heat and cold where the lack of economic loss has meant little resources aimed at reducing loss of life.

I'm sure more nuanced work will likely follow this initial death map.

WASHINGTON (Reuters) – Heat is more likely to kill an American than an earthquake, and thunderstorms kill more than hurricanes do, according to a "death map" published on Tuesday.
Researchers who compiled the county-by-county look at what natural disasters kill Americans said they hope their study will help emergency preparedness officials plan better.
Heat and drought caused 19.6 percent of total deaths from natural hazards, with summer thunderstorms causing 18.8 percent and winter weather causing 18.1 percent, the team at the University of South Carolina found.
Earthquakes, wildfires and hurricanes combined were responsible for fewer than 5 percent of all hazard deaths.
Writing in BioMed Central's International Journal of Health Geographics, they said they hoped to dispel some myths about what the biggest threats to life and limb are.
"According to our results, the answer is heat," Susan Cutter and Kevin Borden of the University of South Carolina wrote in their report, which gathered data from 1970 to 2004.
"I think what most people would think, if you say what is the major cause of death and destruction, they would say hurricanes and earthquakes and flooding," Cutter said in a telephone interview. "They wouldn't say heat."
"What is noteworthy here is that over time, highly destructive, highly publicized, often-catastrophic singular events such as hurricanes and earthquakes are responsible for relatively few deaths when compared to the more frequent, less catastrophic such as heat waves and severe weather," they wrote.
The most dangerous places to live are much of the South, because of the heat risk, the hurricane coasts and the Great Plains states with their severe weather, Cutter said.
The south central United States is also a dangerous area, with floods and tornadoes.
California is relatively safe, they found.
"It illustrates the impact of better building codes in seismically prone areas because the fatalities in earthquakes have gone down from 1900 because things don't collapse on people any more," Cutter said.
"It shows that simple improvements in building codes in high-wind environments like hurricane coasts, and the effectiveness of evacuation in advance of hurricanes, has reduced the mortality from hurricanes and tropical storms," she added.
"So there are some things we are pretty good at in getting people out of harm's way and reducing fatalities."
Cutter said there is no national database on such deaths and this was a first try at getting one together.
