Typical damage for each level of the Enhanced Fujita scale is given below. Damage in a given scenario may recieve a different rating from what is presented here based on quality of construction and other factors.
Note that only a single instance of a given level of damage is needed for a rating, i.e. if a single house takes EF3 damage, and there is no higher damage, then the tornado will be rated EF3.
EF0: Shingles and siding peeled from houses. Weak trees may be toppled. Some tree limbs may snap. Some fences knocked down. Very weak structures may be destroyed.
EF1: Houses suffer severe roof damage, with large sections of surface removed. Poorly connected roofs may be completely torn off. Trailer homes may overturned or partially destroy. Barns and garages destroyed.
EF2: Roofs torn from well-built houses. Some exterior walls may collapse. Trailer homes completely demolished. Barns blown away. Utility poles snapped or flattened.
EF3: Exterior and interior walls fail in well-built houses. Upper stories may be removed. Weaker houses completely leveled. Steel transmission towers crumpled. Weak or poorly anchored structures blown away.
EF4: Well-constructed houses completely leveled and left as piles of debris. Some houses may be blown away. Trees debarked and denuded. Asphalt may peel from some roads.
EF5: Well-constructed, well-anchored houses blown away with foundations wiped clean. Steel-reinforced structures completely destroyed. High-rise buildings deformed.
A tornado's Enhanced Fujita (EF) rating is determined based on the estimated wind speeds and damage caused by the tornado. The rating takes into account the extent of damage to structures, vegetation, and other objects along the tornado's path. The EF scale ranges from EF0 (weakest) to EF5 (strongest), with wind speeds increasing with each higher rating.
The damage from a microburst appears to radiate out from the center while tornado damage occurs along the path that the tornado took. In a microburst trees fall or are bent outwards, with trees that neighbor each other generally falling in the same direction. In a tornado downed trees to not have the same order, and fall in multiple directions. Those left leaning may hint towards an inward or rotating flow. Some tornadoes have roughly crescent shaped areas of more severe damage, indicating a multivortex structure.
I'm unable to show images, but a diagram of the Fujita scale typically shows a series of categories ranging from F0 (weakest) to F5 (strongest) based on the estimated wind speeds and damage caused by a tornado. The scale helps classify tornadoes based on the damage they produce, helping meteorologists assess their strength. You can easily find diagrams of the Fujita scale online for a visual reference.
On average tornadoes cause 60 deaths and and about $500 million dollars in damage each year.
The scale does not rate tornadoes on wind speed but on damage. The wind speeds for the categories (F0, F1 etc) are estimates for each damage level. The wind estimates for F5 damage start at 261 mph. However, this estimates is believed to be too high. On the new scale, the wind estimates for EF5 start at 201 mph.
There are six levels on the EF (Enhanced Fujita) scale running from EF0 at the weakest to EF5 at the strongest.
No. An example of a compound sentence would be:Rain caused damage along the coast and and heavy winds caused damage inland. (two clauses, each with its own subject and verb.)
On average, lightning causes around $900 million in damage each year in the United States. This includes damage to buildings, forests, and infrastructure.
Earthquakes.
In the past 5 years tornadoes in the U.S. have killed 744 people and caused over $15 billion dollars worth of damage. Most of this ocurred as a result of the devastating tornadoes of 2011, which claimed 553 lives and cost approximately $10 billion.
The two are a comparable as apples and oranges. Other than toting up the amount of kilojoules release by each, there is no way to compare the strength of a tsunami and a tornado. The two are quite unrelated. A tornado is a strong whirlwind. A tsunami is a powerful wave in the ocean, usually caused by earthquakes.
A multiple vortex tornado is a tornado that has two or more smaller vorticies inside the main circulation. These subvorticies or suction vortices can have winds up to 100 mph faster than the rest of the tornado, and thus cause more severe damage. This is one reason why one area hit by a tornado may only sustain moderate damage, while the area next to it may be devastated. Normally these vortices are hidden within the main funnel, but if conditions are right a multiple vortex tornado may have two or more funnels. Each subvortex usually only lasts a few seconds.
