- Fujita Scale
This scale describes the intensity of tornadoes based on the damage that they cause. The scale ranges from F0 where damage is light to F5 where damage is catastrophic. The scale was developed by American scientist Tetsuya (Ted) Fujita, a pioneer in tornado research. As of April 1, 2013, this scale has been replaced by the Enhanced Fujita Scale in Canada.
Enhanced Fujita Scale
This scale is an updated and improved version of the Fujita Scale. While the levels of intensity, ranging from EF0 to EF5, have the same relationship to damage as the original F-scale, the associated wind speeds have been made more accurate. It has been in use in Canada since April 1, 2013.
