There was no single F5 tornado, but they have been in fact several dozen in the past few decades. F5 is the strongest category on the Fujita scale capable of completely blowing away well build houses. Since these tornadoes are the strongest and are typically very large they are generally the deadliest and most destructive.
The most recent F5/EF5 tornado was the Moore, Oklahoma tornado of May 20, 2013.
an f5
An F5 Tornado is the most powerful category of tornado possible. This tornado pulls well-built homes off their foundations and into the air before shredding them and wiping the foundation clean.
The Tri-State tornado was most likely an F5.
The F5 (or EF5 as of February 2007) tornado is the most damaging category.
F4 and F5 are the two strongest categories of tornado on the Fujita scale. A damage based scale which rates tornadoes from F0 to F5. An F4 tornado will reduce most houses to piles of rubble. An F5 tornado will completely annihilate almost any house and wipe it clean off its foundation. Winds in an F5 can exceed 300 mph.
f5 is the worst
It is unlikely. There has never been a recorded F5 tornado in Colorado.
A F6 tornado does not exist on the Enhanced Fujita scale, which ranges from F0 to F5. The most powerful tornado category, an F5 tornado, has wind speeds exceeding 200 mph and can cause catastrophic damage.
disastrous as an earthquake/tornado...
No. Florida has never recorded an F5 or EF5 tornado.
It is unlikely. An F5 tornado can gouge out the ground to some depth, but not deep enough to reach most buried coffins.
