To really tear apart most houses a tornado usually has to be of at least EF3 intensity. The U.S. averages about 46 such tornadoes each year, which accounts for about 4% of all U.S. tornadoes.

Does a tornado's low air pressure make houses explode?

No. The pressure drop inside a tornado is not large enough for this to happen. Tornadoes tear houses apart with the power of their wind.


How do tornadoes affect the world and people?

Tornadoes can kill or injure people and damage or destroy their property. Tornadoes can affect the landscape by destroying vegetation and sometimes causing erosion.


What did tornadoes do to houses?

Tornadoes can cause a wide range of damage to a house. A weak tornado may peel back shingles and siding, and break windows, or topple a tree into the house. A stronger tornado may tear the roof off and perhaps some exterior walls. The most violent tornadoes can wipe houses clean off their foundations and scatter them downwind.


Do F5 Tornadoes tear roads off the ground?

F5 tornadoes have the capability to tear roads off the ground due to their extreme wind speeds and powerful winds that can lift and displace heavy objects. The severity of damage caused by a tornado depends on various factors such as the strength of the tornado, the construction of the road, and other environmental conditions.


Do tornadoes cause damage because they cause homes and buildings to cave in?

Tornadoes can cause houses and other buildings to collapse, but most are not strong enough to do that. A typical tornado can tear away parts of roofs, break windows, and topple trees. Entire roofs and walls can go airborne in stronger tornadoes. Weak structures impacted by strong tornadoes often get blown away rather than collapsing. In very violent tornadoes the same thing can happen to well constructed houses.


Can tornados break metal?

Yes, though it depends on the strength of the metal and what form its in. Weak tornadoes can tear aluminum siding from most buildings. Stronger tornadoes can destroy many structures made of sheets of metal. The most violent of tornadoes have been known to bend steel girders.


What is an EF2 tornado like?

An EF2 tornado is considered the beginning of a strong or significant tornado. An EF2 tornado has estimated winds of 111-135 mph. These winds can tear roofs from well built houses, snap large trees, toss cars, and completely obliterate mobile homes. While tornadoes of this strength do not usually kill they are still very dangerous.


What does f2 mean for the damage of tornadoes?

F2 indicates a fairly strong tornado that will tear roofs from well-built houses, lift, small cars, demolish trailer homes, and snap large trees.


Why do tornadoes rip down houses?

Tornadoes produce extremely powerful winds which carry a great deal of force. In some cases this is too much force for a houses to withstand, and the connections holding the different parts of the house together fail.


Why is tear strength lower than breaking strength?

Tear strength involves only individual threads in a garment to be broken. Breaking strength involves all of the weave to be broken.


What sort of damage can a tornado cause?

It depends on the intensity of the tornado. Weak tornadoes (EF0 and EF1) can damage roofs, break windows, snap small trees and topple weak rooted ones, and overturn trailers. Strong tornadoes (EF2 and EF3) snap and uproot large trees, obliterate trailers, and tear roofs and walls from frame homes. Violent tornadoes (EF4 and EF5) debark trees, level or blow away well-built houses, and can tear asphalt from roads.


Does a tornado's low air pressure often make houses explode?

No, houses are more likely to be damaged by the strong winds and flying debris associated with a tornado rather than from the low air pressure. Most houses are not airtight enough for the pressure differences caused by a tornado to make them explode.
