The maps below show tornado concentration (the number of tornadoes per 10,000 square miles of area) over the 20-year period from 1991 to 2001. Map (a) shows the concentration of all tornadoes over the period. Map (b) plots only the larger tornadoes—EF-3 and above. a. Looking at map (a), what two states have the highest annual concentration of tornadoes? (I have also provided a map that includes state names at the bottom of this page if you do not already know them). b. Looking at map (b), what two states have the most frequent large tornadoes, EF3-EF5? c. What is the strip of land extending from east Texas to eastern Kansas/Nebraska commonly called due to the high incidence of tornadoes in that region?
