Following two particularly devastating tornadoes in 1997 and 1999, engineers questioned the reliability of the Fujita scale. Ultimately, a new scale was devised that took into account 28 different damage indicators; this became known as the Enhanced Fujita scale.[4] With building design and structural integrity taken more into account, winds in an EF4 tornado were estimated to between 166mph and 200mph.[5] The Enhanced Fujita scale is used predominantly in North America. Most of Europe, on the other hand, uses the TORRO tornado intensity scale (or T-Scale), which ranks tornado intensity between T0 and T11; F4/EF4 tornadoes are approximately equivalent to T8 to T9 on the T-Scale. Tornadoes rated IF4 on the International Fujita scale are also included on this list.
