About 1,000 tornadoes touch down in the United States every year. One of the most powerful of these struck Greensburg, Kansas, in May 2007. With wind speeds of up to 205 miles per hour, the tornado destroyed 95 percent of the town in twenty minutes. Ten people were killed. Severe weather scientists study these types of deadly storms to discover how more lives can be saved. Tornadoes: The Science Behind Terrible Twisters explains how tornadoes develop, describes the technology and storm chasers that help predict and track the storms, and provides safety tips for surviving a terrible twister.
