As you peruse through our website, you often see the name, Thomas Grazulis. His in depth research is the basis for much of our work and we wanted to add space on our site to lead you to HIS site! 

The Tornado Project has been locating, organizing and publishing information on tornadoes since 1970. Tom’s latest book, “Significant Tornadoes 1974-2022,” chronicles every “significant” tornado (F2 or EF2 and above) that has struck in the United States during those years.

Tom is currently working on the next volume which covers significant tornadoes prior to 1974!
