According to the National Weather Service, doing so could actually increase the risk of death, in part because the wind from a tornado is thought to accelerate as it flows under the overpass, in what's known as the wind tunnel effect.

Researchers have found that survivors of natural disasters have the potential to experience positive changes or growth in addition to the stress they experience. Researchers say this finding can help those working in communities after a disaster.

Engineering researchers analyzed Google Earth images of the massive 2011 Tuscaloosa, Ala., and Joplin, Mo., tornadoes and found similarities between the two in behavior and interaction with the terrain. The findings likely apply to all tornadoes. Tue, 27 Aug 2013 11:19:13 EDT //www.koonmotors.com/releases/2013/08/130827111913.htm
