In 2023, it was announced by the Storm Prediction Center and National Weather Service Norman, Oklahoma that the 1970 Lubbock tornado was originally rated F6, which was later downgraded to its official rating of F5. [15]

The Enhanced Fujita scale (abbreviated EF-Scale) is a scale that rates tornado intensity based on the severity of the damage a tornado causes. It is used in the United States and France, among other countries. [1]

Well-constructed houses leveled; structures with weak foundations blown off some distance; cars thrown and large missiles generated.

2023年3月19日 · After viewing the aerial photos of the storm damage in Xenia, Fujita officially rated the tornado as an F6. This was the second and last time that a tornado was rated as an F6.

Without a thorough engineering analysis of tornado damage in any event, the actual wind speeds needed to cause that damage are unknown. The Enhanced F-scale was implemented in …

2023年7月12日 · In summary, there has never officially been an F6 tornado according to modern records and measurement scales. However, a small number of tornadoes have been estimated to reach wind speeds and cause damage consistent with …

2021年10月21日 · While (E)F6 tornadoes may not be impossible, and the categorization does theoretically exist... in practicality, there is no need for such a value, as the damage would be complete whether in an (E)F5 or (E)F6+.

The original Fujita Scale and the new Enhanced Fujita Scale is used to rate the intensity of a tornado by examining the damage caused by the tornado after it has passed over a man-made structure.

2025年1月26日 · Many people believe that an F6 tornado has occurred, but this classification does not exist officially. This section will explore the theoretical maximum of the Fujita scale, …

2025年1月11日 · In reality, no tornado has officially reached the F6 level, despite theoretical discussions. The Fujita Scale, created by Dr. Ted Fujita, categorizes tornadoes based on damage. The scale extends only to F5, which denotes winds over 261 mph.
