F4 Tornadoes
This is a list of tornadoes which have been officially or unofficially labeled as F4, EF4, IF4, or an equivalent rating. These scales – the Fujita scale, the Enhanced Fujita scale, the International Fujita scale, and the TORRO tornado intensity scale – attempt to estimate the intensity of a tornado by classifying the damage caused to natural features and man-made structures in the tornado's path. Tornadoes are among the most violent known meteorological phenomena. Each year, more than 2,000 tornadoes are recorded worldwide, with the vast majority occurring in North America and Europe. In order to assess the intensity of these events, meteorologist Ted Fujita devised a method to estimate maximum wind speeds within tornadic storms based on the damage caused; this became known as the Fujita scale. The scale ranks tornadoes from F0 to F5, with F0 being the least intense and F5 being the most intense. F4 tornadoes were estimated to have had maximum winds between and . F ...

London Tornado Of 1091
The London Tornado of 1091 is the earliest reported tornado in England, occurring in London on Friday, 17 October 1091. It has been reckoned by modern assessment as possibly a T8 on the TORRO scale (roughly equivalent to an F4 on the Fujita scale) making it potentially the strongest recorded tornado in the British Isles, although this estimate is based on reports written 30 years after the tornado. The church of St Mary-le-Bow in the city of London was badly damaged; four rafters long were driven into the ground so that only protruded above the surface. Other churches in the area were demolished, as were over 600 (mostly wooden) houses. For all the damage inflicted, the tornado claimed just two known victims from a population of about 18,000. The tornado is mentioned in chronicles by Florence of Worcester and William of Malmesbury, the latter describing it as "a great spectacle for those watching from afar, but a terrifying experience for those standing near".

1946 Windsor–Tecumseh Tornado
On June 17, 1946, the most powerful tornado to strike Windsor, Ontario, moved through the town at F4 intensity. The tornado touched down near River Rouge, Michigan, then crossed the Detroit River and made landfall in the Brighton Beach neighbourhood of Windsor. It then cut across southern Windsor and northern Sandwich West Township, Ontario (now the Municipality of LaSalle, Ontario), along a path in length. It also cut across Highway 3 before weakening somewhat. The storm then touched down as an F4 again at the modern-day intersection of Walker Road and Grand Marais Road, near the center of the city. Path of destruction The tornado took a northeastward path, cutting through farmland and forest, an area with few housing subdivisions (at the time, but still many homes), and narrowly missing Windsor Airport (which was located just south of the tornado), before tearing through the northwest part of the Town of Tecumseh, Ontario and dissipating over Lake St. Clair.
