F1 corresponds to the twelfth level of the Beaufort scale, and F12 corresponds to Mach number 1.0. F0 was placed at a position specifying no damage (approximately the eighth level of the …

Strong frame houses lifted off foundations and carried considerable distances to disintegrate; automobile sized missiles fly through the air in excess of 100 meters; trees debarked; steel re …

Below is a brief description of each type of tornado on the Fujita scale. F0 Tornado. Broken branches; shallow rooted trees pushed over; some chimney damage. F1 Tornado. Surface …

The version used today—the Enhanced Fujita Scale—ranges from EF0 tornadoes with winds of 65 to 85 miles an hour, to EF5 tornadoes with winds exceeding 200 miles an hour. The U.S. …

The Fujita Tornado Scale, usually referred to as the F-Scale, classifies tornadoes based on the resulting damage. This scale was developed by Dr. T. Theodore Fujita (University of Chicago) …

The Seymour, Texas, tornado of April 10, 1979 is a prime example of a tornado that is destined to be misjudged on the Fujita Scale. This spectacular funnel was probably capable of F4 …

A system of estimating and reporting tornadic wind intensity devised by Professor T. Theodore Fujita (1920-1998) and path length and width by Allen Pearson in 1971, based on the …

The scale was original created in 1971 by Dr. Fujita as a way of determining the strength of tornadoes from the damage that they caused. Like many of the contributions of Dr. Fujita, it …

On the Enhanced Fujita Scale, the tornado damage scale that replaced the Fujita Scale, an F1 tornado is now an EF1 tornado. An EF1 tornado has wind speeds between 86 and 110 mph …

From 1950 to 2011, F0 and F1 tornados account for 4% of all tornados related deaths in the United States. A tornado rated an F1 has winds speeds between 73 to 112 MPH (117 to 180 …
