Screen Shot 2014-03-25 at 3.32.44 PMThe Smithsonian Magazine has a very cool interactive map feature describing all of the tornadoes across the United States since 1980. As all thoughts turn to Spring, especially after such a brutal winter for many, others begin to think of something else. In the central and southern United States, Spring signals the return of a force of destruction: tornado season.

Generally, these dangerous storms run from late winter to mid summer, but the season tends to vary slightly from region to region. A new interactive map from ESRI allows you to explore the history of tornadoes in your own state, region, or even backyard. The map shows every tornado to touch down in the U. S. from 1980 to 2012, and includes details on casualties and where each ranks on the Enhanced Fujita scale. The scale is calculated from the damage that the tornado inflicted and the wind speeds that would have been required to inflict such devastation.
