Is "Tornado Alley" expanding?

(CNN)--It's not Tornado Alley anymore, how about Tornado Field?

According to a report by CoreLogic, a California-based research and consulting firm, tornadoes are striking in more parts of the U-S, more often.

The traditional boundaries of Tornado Alley center on the Plains states of Texas, Oklahoma, Kansas, Nebraska and South Dakota.

Researchers think it should be expanded to include much of the Midwest and Deep South.

Only one state in the traditional Tornado Alley - Kansas - was among the top five states for the most tornadoes from 1980 to 2009.

Tornadoes and the storms that generate them account for 57-percent of insured catastrophic losses in the U-S each year.
