A tornado damage survey, also known as a storm damage assessment, is a type of land survey that is conducted to determine the damage caused by tornadoes, and to give them ratings on the Enhanced Fujita scale. Damage surveys have been used since the 18th century to determine tornado-caused damage, and have become increasingly common following ...
The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.
This is a list of tornadoes which has been officially or unofficially labeled as F3, EF3, IF3 during the 2020s decade. 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 ...
The 1977 Birmingham–Smithfield F5 tornado's damage was surveyed by Ted Fujita and he "toyed with the idea of rating the Smithfield tornado an F6". [13] In 2001, tornado expert Thomas P. Grazulis stated in his book F5–F6 Tornadoes; "In my opinion, if there ever was an F6 tornado caught on video, it was the Pampa, Texas tornado of 1995". [14]
An EF4 tornado with wind speeds ranging from 166 to 200 mph can cause devastating damage. Most to all walls on a well-built house will likely collapse, and high-rise buildings can sustain ...
Each year, more than 2,000 tornadoes are recorded worldwide, with the vast majority occurring in North America and Europe. [9] 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.
