Where have the biggest tornadoes been?

The highest winds ever recorded were in the F5 tornado that hit the Oklahoma City area on May 3, 1999. Winds were measured at 302 mph. However, wind measurements in tornadoes are rare, so other tornadoes were probably stronger, especially considering that some have produced more extreme damage. The most severe damage ever documented came from the tornado that hit Jarrell, Texas on May 27, 1997. In one section of town, every single structure was blown away, leaving no debris and no survivors. In this neighborhood trees, grass, streets, driveways, and over a foot of soil were completely stripped away, reducing the area to a field of mud and concrete slabs.
