Lightning risk

Since 1969, ninety-four persons were reportedly killed annually by lightning in the United States. Reported injuries were almost three times the fatalities. These casualties were not evenly distributed across the country. The purpose of this paper was to examine the expected distribution of these occurrences using known ecologic risk factors. Lightning fatalities and injuries were related to thunderstorm days, population characteristics, and land area. The resulting predicted casualties were mapped and indicate where preventive measures are needed. This same technique could be employed to examine most natural hazard risks using existing data.
