Well built homes leveled but left on foundations. Weakly anchored houses blown off foundations. Trees stripped of bark. In some cases asphalt may be torn from roads.
The estimated wind range for an F4 tornado is 207-260 mph. On the Enhanced Fujita scale this was change to 166-200 mph for an EF4 tornado.
An F4 tornado can be quite devastating. The typical damage indicator for an F4 tornado is well-constructed houses that are completely leveled. Even structures not impacted by the strongest winds of the tornado are likely to be severely damaged. Although it is not always the case, F4 tornadoes are often quite large, often over a quarter of a mile wide, with a fair number growing to over a mile across. This means that they can create large swaths of damage. In some cases entire towns may be destroyed. Although most tornadoes that go down in history are in the F5 category, a few F4 tornadoes have made the list as well.
The winds in an F4 tornado range from 207 to 260 mph (333-418 km/h). These extreme winds can cause devastating damage to structures and landscapes. It is crucial to take immediate safety precautions when such tornadoes are approaching.
The general damage indicator for an F4 tornado is well built houses completely leveled and left as piles of rubble. In the U.S. this has been replace by the EF4 category, which is on a somewhat less arbitrary scale. While the overall damage is essentially the same, more factors are taken into account such as quality of construction. On the new Enhanced Fujita scale an EF4 rating is given to a tornado with estimated peak winds in the range of 166 to 200 mph.
Simple predicate italicized, complex predicate in bold.The center of a tornado can cause a great deal of damage.
Tornadoes are rated not based on the quantity of the damage they cause but on the severity. In an F4 tornado well-constructed houses are completely leveled and left as piles of rubble. Houses not securely anchored to their foundations may be blown away. Trees are stripped of their bark and asphalt may be peeled from roads.
The estimated wind range for an F4 tornado is 207-260 mph. On the Enhanced Fujita scale this was change to 166-200 mph for an EF4 tornado.
While it would be possible for a tornado to cause major damage to a significant portion of Washington D.C. (in 2002 a large F4 tornado came within 30 miles), no tornado would be large enough to affect the entire city.
Typical F4 damage includes well built houses leveled, poorly anchored houses blown away, and trees stripped of bark.
The infamous 1979 Wichita Falls tornado was an F4.
Facts about F4 and EF4 tornadoes:In assessing tornado damage, the most difficult difference to determine is between (E)F4 and (E)F5 damage as both involve structures that are completely destroyed.The winds required to do F4 damage were originally estimated at 207-260 mph. However in the 21st century this estimate was found to be too high an was lowered to 166-200 mph for an EF4 tornado.Although F5 and EF5 tornadoes are generally the most destructive, several F4 tornadoes have temporarily held the title of costliest tornado in U.S. history. Most recently the Tuscaloosa, Alabama EF4 tornado of 2011 held that title with damage totaling $2.2 billion until the Joplin, Missouri EF5 tornado beat that record three weeks later.Even though F5 tornadoes are generally deadlier, more deaths in total result from F4 tornadoes because they are more common.
An F4 tornado can be quite devastating. The typical damage indicator for an F4 tornado is well-constructed houses that are completely leveled. Even structures not impacted by the strongest winds of the tornado are likely to be severely damaged. Although it is not always the case, F4 tornadoes are often quite large, often over a quarter of a mile wide, with a fair number growing to over a mile across. This means that they can create large swaths of damage. In some cases entire towns may be destroyed. Although most tornadoes that go down in history are in the F5 category, a few F4 tornadoes have made the list as well.
An F4 tornado is classified as an intense tornado with wind speeds between 207-260 mph. The damage it can cause is devastating, often leveling well-constructed houses and sending cars flying through the air. The path of destruction can be several miles long and a mile wide.
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.
An F4 tornado can be a quarter of a mile wide, but that is by no means a requirement. Tornado ratings are based on the severity of the damage, not the size of the tornado. There is a tendency for violent tornadoes to be large, but they don't have to be. A path width of 1/4 mile would not be uncommon for an F4, but sizes have ranged from as small as 100 yards to as wide as 2.5 miles.
No. The highest rating a tornado can receive on the Fujita scale is F5. F4 is the second highest rating. Even then, while very strong tornadoes tend to be large, ratings are not based on size; they are based on the severity of damage the tornado inflicts.
Stripping bark from trees is usually considered F4 damage.
