Comparison of natural disaster fatalities in the United States. Cumulative
size-frequency distributions for annual earthquake, flood, hurricane, and
tornado fatalities. In addition to demonstrating linear scaling behavior
over 2 to 3 orders of magnitude in loss, these data group into two families.
Hurricanes and earthquakes are associated with relatively flat slopes (D=
-0.4 to -0.6); while floods and tornadoes have steeper slopes (D= -1.3
to -1.4). Open symbols were not used to calculate slope of lines.
