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.
One tornado was reported to have thrown a house 1/4 mile.
Yes, it takes a strong tornado to do this usually at least EF3. The most violent tornadoes can completely blow a house away.
People have been carried several miles by tornadoes, though those people have not survived. The longest recorded distance a person has been carried and lived was about a quarter mile.
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.
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.
No. Tornadoes tear houses apart with wind and debris. The notion that the low pressure inside a tornado makes houses explode has been disproven.
Tornadoes can kill or injure people and damage or destroy their property. Tornadoes can affect the landscape by destroying vegetation and sometimes causing erosion.
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.
Generally only the strongest tornadoes, those rated EF4 and EF5, can lift houses. In a tornado air spirals upward rapidly, which is why they can lift objects into the air. The stronger the wind, the heavier things it can lift. In the strongest tornadoes this upward component of the wind is strong enough to tear houses from their foundations and lift them into the air. A tornado of EF3 or perhaps even EF2 intensity can lift a house that is not properly anchored.
An F3 tornado will tear walls from most houses sometimes leaving only a few walls standing. Contrary to popular belief tornadoes do not cause houses to explode.
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.
tear resistance is not the same as tensile bond strength.
Tear strength involves only individual threads in a garment to be broken. Breaking strength involves all of the weave to be broken.
F2 indicates a fairly strong tornado that will tear roofs from well-built houses, lift, small cars, demolish trailer homes, and snap large trees.
Yes. There have been documented cases of F5 tornadoes and some F4 tornadoes tearing asphalt from roads.
