Is an F12 tornado possible?
The original Fujita Scale actually goes up to F12. An F12 tornado would have winds of about 740 MPH, the speed of sound. Roughly 3/4 of all tornadoes are EF0 or EF1 tornadoes and have winds that are less than 100 MPH. EF4 and EF5 tornadoes are rare but cause the majority of tornado deaths.
Is an F6 tornado possible?
There is no such thing as an F6 tornado, even though Ted Fujita plotted out F6-level winds. The Fujita scale, as used for rating tornados, only goes up to F5. Even if a tornado had F6-level winds, near ground level, which is *very* unlikely, if not impossible, it would only be rated F5.
Can a f5 tornado pick up a tank?
The only tornado that would be able to do serious damage to a 70 ton tank is an EF-5. Depending on how strong the winds are, and if it can catch the tank, it will move, and definitely damage it, but not in the same way as a semi truck or freight train.
How rare are EF5 tornadoes?
EF-5 tornadoes are among the rarest cyclones on the planet. In the U.S., there have been only 59 EF-5 twisters since 1950, according to NOAA's Storm Prediction Center. That works out to an average of less than one EF-5 tornado in America each year.

The chances of surviving the most powerful tornado possible without a concrete reinforced safe room or a basement are "pretty slim" LaDue told ABC News. "People are not trained and prepared," LaDue said. "There is very little collective knowledge or history, and certainly most people don't have a memory of what these things can do.".
Is Smithville a tornado?
The Smithville tornado has been preliminarily categorized as an EF-5 based on photos, but a complete survey of the damage is required before the classification is confirmed. In order for a tornado to be eligible for EF-5 classification the twister must have winds of 200 miles per hour or greater for about three seconds.
What is the EF5 tornado?
An EF5 represents the most violent tornadoes we have ever seen - and will ever see. Monday's event was just the 59th on record since 1950. But arriving at that one, simple number is a subtle and subjective business.
What is the EF0 scale?
Enter the Enhanced Fujita scale - the EF that precedes the ratings we see when tornadoes strike - which came into use from 2007. At the EF0 end, damage is characterised as "Light"; the high end remains "Devastating" and "Incredible".

At its simplest, the highest level of the "Enhanced Fujita scale" indicates the highest wind speeds - greater than 320 km/h (200mph). Unlike the rest of the scale, EF5 has no upper limit.
How many damage indicators are there?
It takes into account a list of 28 Damage Indicators - a list of the types of buildings or vegetation that may have suffered damage.
Is the EF scale subjective?
Yet storms like the one that struck Moore on Monday still present a confused picture. The EF scale remains a subjective measure, and distinguishing between the two highest levels remains a matter of some debate among weather experts.
Does the wind speed scale overestimate wind?
Estimates based on damage to buildings, for example, did not take into account how well-constructed the buildings were, and because damage can far outstrip the wind-speed ratings of many homes, the scale was believed to overestimate winds at the higher end of the scale.
How to survive an EF5 tornado?

How violent are tornadoes?
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 the United States 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. F5 tornadoes were estimated to have had maximum winds between 261 mph (420 km/h) and 318 mph (512 km/h).
What scale is used to measure the intensity of a tornado?
These scales – the Fujita scale, the Enhanced 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.
Why are tornado ratings lower?
Additionally, because tornado ratings are damage-based, many tornadoes capable of causing F5/EF5 damage, such as those that move through rural areas, may receive lower ratings because their strongest winds do not impact any suitable damage indicators.
When did the F5 tornado occur?
The work of tornado expert Thomas P. Grazulis revealed the existence of several dozen likely F5 tornadoes between 1880 and 1995.
How many people died in the F5 tornado?
On that day, an F5 tornado, packing winds exceeding 260 mph (420 km/h), hit the downtown and suburban areas, with horrific results. 114 people would die, and hundreds more were injured. Hundreds of buildings were destroyed, and over 2,000 cars were totaled. The only saving grace was that the tornado wasn’t at its peak intensity as it moved through downtown.
What does EF stand for in building?
First off, the correct term is now “EF”, which is an acronym for “Enhanced Fujita”. The original Fujita Scale was revised in 2007 to account for unique building codes.
How safe are skyscrapers from tornadoes?
Wind speeds in an urban area with several skyscrapers such as New York City, Chicago, and Seattle would be exaggerated immensely if they were ever struck by a tornado. However, even the winds from the strongest of tornadoes, F5s, probably wouldn’t cause structural failure. So, they are fairly safe compared to structures that are made of timber. High rises may not fair as well depending on how you define a high-rise. Usually a building has to be 75 feet tall to qualify as such. If a 75-foot tall structure is composed primarily of timber it would be utterly destroyed by the strongest of twisters. Otherwise, your main concern would be broken glass and flying debris. If you’re in a skyscraper during a tornado and don’t have the luxury of a warning before you are aware of its presence in your vicinity, you should do the same thing that someone in a house in Oklahoma with no basement would do, which is to go to the most interior part of the building. Most skyscrapers have basements, but you probably won’t have time to get to one if you don’t know that a tornado is about to impact the area you’re occupying. Elevators are probably your second best option. They are the strongest part of a building.
What happens when a tornado hits a city?
When a tornado reaches a big city, the consequences can be devastating. Just as wooden home can collapse in the tornado’s violent winds, the same twister can shatter windows in skyscrapers. This creates a maelstrom of debris on the ground below. It can damage brick buildings and just rip apart cars.

What is the EF5 myth?
The “nothing can survive an EF5” myth is a detriment to policies concerning home and commercial building construction, says Timothy Marshall, a meteorologist and a civil engineer at Haag Engineering in Dallas. “The logic goes: If nothing can survive, why do anything?”.
Why is it difficult to measure tornado wind speed?
Directly measuring a tornado’s wind speed is difficult because the storms tend to destroy instruments. So meteorologists have to estimate tornado wind speeds. The original “Fujita Scale” that ranked these estimates was used from 1971 to 2007, but the estimates weren’t really based on actual, measured tornado wind speeds.
How many people died in the Joplin tornado?
The tornado that killed 162 people and damaged more than 8,000 buildings in Joplin, Mo. in May 2011 provides another example of how, even in the most severe storms, most damage is done by comparatively weak winds.
When did the F5 tornado hit Moore?
Marshall has studied how buildings withstood the F5 twister that tore through Moore on May 3, 1999 as well as the EF5 on May 20, 2013. What he says seems surprising: Most of the destruction in an EF5 doesn’t come from 200 mph winds, it comes from much weaker winds.
Can anything survive an EF5 tornado?
One reason, researchers say, is a public perception that “nothing can survive an EF5 tornado.” Indeed, it’s hard to imagine any structure outlasting the violent winds and the devastating cloud of shrapnel that accompanies an EF5.
Is an EF5 tornado survivable?
And despite the horrific scenes of tornado destruction that have become all too familiar in Oklahoma, EF5 tornadoes are survivable — both for people and structures. And that has important public policy implications.
Understanding The Scale
Structures & Building Codes
- The “nothing can survive an EF5” myth is a detriment to policies concerning home and commercial building construction, says Timothy Marshall, a meteorologist and a civil engineer at Haag Engineering in Dallas. “The logic goes: If nothing can survive, why do anything?” Marshall told StateImpact in a July interview. Just because a tornado is given an EF5 designation doesn’t …
People & Storm Shelters
- The EF5 question isn’t just about building codes. It also relates to tornado shelters. As the Gawker commenter above illustrates, many people believe that the destructive power of an EF5 makes an underground shelter the only safe place to go. That isn’t true. Properly built, above-ground safe rooms — typically a hardened indoor closet or room reinf...
