Flying debris can shatter windows and doors. If the tornado is strong enough, it can blow the roof right off of a building or knock down walls. In the worst cases, structures can be leveled to the ground or even completely blown away. The severity of damage can be rated on the Enhanced Fujita (EF) scale.

How long does it take to destroy structures with a tornado?
It varies depending on the structure and the intensity of a tornado. In most cases, though, it takes a matter of seconds, which is usually how long a structure is exposed to the strongest winds. One analysis of the fast-moving EF5 tornado that hit Smithville, Mississippi tornado of 2011 found that houses wiped clean off their foundations were exposed to the strongest winds of the tornado for less than 3 seconds.
How do you find out the strength of a tornado?
The strength of a tornado is determined by the damage it does to man-made structures and vegetation. When a structure takes damage from a tornado, the degree of damage, the type of structure, and its quality of construction are used to estimate the strength of the winds that caused that damage. This is then used to sort the tornado into one of six intensity categories of the Enhanced Fujita Scale, ranging from EF0 at the weakest to EF5 at the strongest.
How can a double tornado stay on ground?
A "double tornado" is scientifically known as a multiple vortex or multivortex tornado. In such tornadoes smaller vortices form within the main vortex of the tornado. These subvortices usually do not last long and individually do not impact the overall tornado very much. Rather than indicating a lack of organization in the tornado, a multivortex structure usually indicates a strong tornado.
What is the most resistant structure during a tornado?
The most resistant structures are those made of steel reinforced concrete.
Why does the size of a tornado not determine the damage of a tornado?
The damage severity in a tornado is determined primarily by wind speed. For example, a tornado with peak winds of 100 mph, even if it is very large, is not going to obliterate well built houses, thought it will cause severe roof damage. By contrast, even a relatively small tornado with peak winds of 250 mph can completely destroy just about any structure.
Can lightning stop a tornado?
No, lightning has little to no affect on a tornado.
In which direction is the position of Tornado Ally shifting if it is and how is this going to affect intensity?
The area of greatest tornado activity appears to be shifting northward. It is unknown how this might affect tornado intensity.
Who does a tornado affect?
A tornado affects anyone unfortunate enough to be in the path of one.
What can be done to a structure to prevent damage from a tornado?
Hello
What is done to a structure to prvent damge from a tornado?
Hello
Can a tornado pass over a fork in a river?
Yes. A river, forked or not, will not affect a tornado.
What happenswhen a lightning bolt hits a raging tornado?
Nothing happens. The lightning will not affect the tornado.
Do tornaodes really affect the earth's surface?
Yes, a tornado is not considered a tornado unless it reaches the ground.
Can a tornado destroy a fire department?
Yes. A strong enough tornado can destroy just about any manmade structure. A tornado of high EF3 intensity or stronger should be enough.
Is a cement house with steel girders safe from a tornado?
It probably would be. It would take an extremely strong tornado to destroy such a structure.
What temperature when a tornado is coming?
tornado formation is not based on temperature, but upon storm structure. you cannot use temperature to determine tornados
How can a tornado affect the ecosystem?
The main impact of a tornado on ecosystems is the destruction of trees and other vegetation. Animals caught in a tornado may be killed or injured as well.
