EF4 damage consists of well-built houses being completely leveled. Some houses, usually with weaker connections to their foundations may be blown off their foundations. Bark will be stripped from trees. Roads that are not well maintained may have sections of asphalt peeled away.
EF5 damage consists of very well constructed houses being swept off their foundations. Sections of topsoil may be scoured away.
Because both levels of damage deal with structures that are completely destroyed, it is often difficult to tell the difference between EF4 and EF5 damage. Of all distinctions between tornado ratings, this is the most difficult to determine.
Note that in either case, only a small protion of the damage path of a tornado will suffer the maximum degree of damage. It only takes one instance of EF5 damage to rate a tornado EF5, and likewise for an EF4 rating.
What else can I help you with?
What does EF4 or EF5 mean?
EF4 and EF5 are ratings on the Enhanced Fujita scale, which uses damage done by a tornado to assign an intensity rating. The scale runs from EF0 to EF5. EF4 and EF5 are the two highest ratings indicating a violent tornado. An EF4 tornado has peak estimated winds of 166-200 mph. Such tornadoes level well-built houses and can strip the bark from trees. EF5, the highest rating, is assigned only to the most powerful of tornadoes with estimated winds over 200 mph, with some having winds in excess of 300 mph. Tornadoes of this strength wipe well-built houses clean off their foundations, completely blowing them away.
What does an EF4 and EF5 tornado look like?
There is no given appearance for a tornado of any given rating, though EF4 and EF5 tornadoes tend to be very large, typically taking on the appearance of large wedges or columns, but not always. If there is enough visibility an EF4 or EF5 tornado will often show very violent rotation.
Which are the most destructive tornadoes?
EF4 and EF5 are destructive with EF4 winds up to 166-200 and EF5 over 200mph destructive tornadoes like these can level houses and even completely blow them away.
How does a meteorologist know how a mild tornado or a strong tornado?
Meteorologists and engineers examine the damage done by a tornado a rate if from EF0 to EF5 based on how severe the damage is. EF0 and EF1 (light to moderate damage) tornadoes are considered weak. EF2 and EF3 tornadoes are classified as strong. EF4 and EF5 tornadoes are classified as violent.
What type of tornadoes are responsible for the most deaths?
mostly an EF5 tornado and sometimes EF3 or EF4 tornadoes
What percent of all tornadoes earn a violent ranking on the fujita scale?
Less than 1% of tornadoes earn a violent rating (F4 or F5) on the Fujita Scale. The same applies the the Enhanced Fujita scale with EF4 and EF5 tornadoes.
What is an EF4 tornado?
The Enhanced Fujita Scale is a system of rating tornadoes based on damage. It goes from EF0 to EF5. EF4 is the second strongest category on the scale, with estimated winds of 166 to 200 mph. An EF4 tornado causes devastating damage. Trees are stripped of their bark and well-built houses are leveled. Houses that are not well-built may be swept away.
Can a tornado demolish a mobile home?
Yes, easily. Tornadoes are rated on a scale that ranges from EF0 for the weakest to EF5 for the strongest. On this scale the complete destruction of a mobile home is usually considered EF2 damage while partial destruction is often rated as EF1. By contrast the complete destruction of a well-built frame house is considered EF4 or EF5 damage.
How fast does an EF4 tornado go?
There is no such thing as an E4 tornado. An EF4 tornado has peak estimated winds of 166-200 mph. In some cases, however a tornado rated EF4 may have been capable of producing EF5 damage (winds over 200 mph) but did not impact any structures that culd yield an EF5 rating.
Is there the potential for violent tornadoes tomorrow for April 14th 2012 EF4?
Yes. The outlook for April 14, 2012 mentioned some risk for violent tornadoes, referring to tornadoes of EF4 and EF5 intensity.
What is the difference between a strong and a violent tornado?
A strong tornado is one that is EF2 or stronger. A violent tornado is one that is EF4 or EF5.
What category is a 200 mile per hour tornado?
On the Ehnahnced Fujita scale, 200 mph is a borderline EF4/EF5 tornado.
