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.
A Category 5 hurricane-proof log house is resistant to winds up to 245 miles per hour (394 km/h). Wall logs in such construction must be made of glued laminated timber and all other components of the house, including hurricane straps, must be hurricane-resistant.
Wind speed alone is not enough to determine the intensity of a tornado. [3] An EF0 tornado may damage trees and peel some shingles off roofs, while an EF5 tornado can rip well-anchored homes off their foundations, leaving them bare— even deforming large skyscrapers.
But he said the wind speed gauge used was 250 metres lower and in an area that was more protected from gales. Ridge tiles from a house landed on this car just three weeks old [Anand Patel]
From these wind speed numbers, qualitative descriptions of damage were made for each category of the Fujita scale, and then these descriptions were used to classify tornadoes. [ 9 ] At the time Fujita derived the scale, little information was available on damage caused by wind, so the original scale presented little more than educated guesses ...
TORRO claims it differs from the Fujita scale in that it is "purely" a wind speed scale, whereas the Fujita scale relies on damage for classification, but in practice, damage is utilised almost exclusively in both systems to infer intensity. That is because such a proxy for intensity is usually all that is available, although users of both ...
A house suffered major roof damage and had one of its exterior walls blown out, while a wooden 2x4 was speared through the front wall of another house that had its windows shattered. Several other homes sustained minor roof shingle damage, a power pole was snapped, and a metal storage shed was lofted and thrown. [72] EF0 Harkers Island (2nd ...
