No. The damage tornadoes do varies widely depending on how strong they are and where they hit. A tornado that stays over open country will cause a lot less damage than one that hits a city. There are six levels of tornado on the Enhanced Fujita scale, which uses damage to rate tornado strength. Here are those categories with typical damage and frequency in the past 20 years in the U.S:
- EF0: peak winds 65-85 mph. Some roof tiles and siding peeled away. Tree limbs broken with shallow rooted trees uprooted. Account for 62% of tornadoes and 0.5% of tornado deaths.
- EF1: peak winds 86-110 mph. House roofs severely damaged. Trailers overturned or partially destroyed. Windows broken. Account for 27% of tornadoes and 5% of tornado deaths.
- EF2: peak winds 111-135 mph. Roofs torn from well-built houses with most walls left standing. Trailers completely destroyed. Large trees snapped and uprooted. Account for 8% of tornadoes and 12% of tornado deaths.
- EF3: peak winds 136-165 mph. Roofs and walls torn from well-built homes. Large vehicles tossed. Most trees in a forest uprooted. Account for 2.5% of tornadoes and 31% of tornado deaths.
- EF4: Peak winds 166-200 mph. Well-built houses completely collapse. Trees debarked. Asphalt peeled from roads. Account for 0.5% of tornadoes and 26% of tornado deaths.
- EF5: peak winds over 200 mph. Well-built houses completely obliterated and swept away, leaving bare foundations. reinforced concrete structures severely damaged. Account for 0.05% of tornadoes and 25% of tornado deaths.

Is there a tornado that is harmless?
No. Some tornadoes touch down in open fields and cause no damage or injuries. However, all tornadoes have the potential to cause harm, even EF0 tornadoes. There are some whrilwinds that are harmless, such as most dust devils. These are not tornadoes, though they sometimes look like them.
Are there different types of tornadoes?
All tornadoes have a common origin and are therefore basically the same. However the number and strength of the vortices produced can vary.
Are all tornadoes alike?
No. Tornadoes vary greatly in strength, size, duration, speed of travel, and appearance.
What are the 3 postulates of science?
1. Every phenomenon has a cause.2. Every cause can be known and understood.3. All causes and phenomena act the same always and everywhere.
How tornadoes be different from another?
There are many ways in which tornadoes can differ. They can differ in wind speed, winds may range from 65 mph to over 300 mph, though the lower wind ranges are more common. They can differ in diameter, ranging from less than 10 yards wide, to the record size of 2.5 miles. Distance traveled can range from several yards to over 200 miles (the record is 219 miles). Tornadoes can range from being nearly stationary to traveling at over 70 mph. Tornadoes differ in how long they last, ranging from a few seconds to over 3 hours. Tornadoes can even differ in structure. Some tornadoes are a simple single vortex while others have a downdraft moving down the center, this can produce multiple smaller vorticies within the funnel. All of these factors combined with where and when a tornado hits influences how much damage occurs and how many deaths and injuries there are.
