There were 45 tornado fatalities in the U.S. in 2010 and 11 more in other parts of the world.
Yes. Tornadoes produce the most destructive winds on Earth. Hurricanes can have higher death tolls, but for them, wind is not the greastest danger.
Records list three killer tornadoes striking Minnesota on April 14, 1886. The listed death tolls of these tornadoes add up to 77. Since death tolls from this time are difficult to determine exactly, 79 is probably a reasonable figure. Most of the deaths are attributed to a single tornado that devastated the towns of St. Cloud, Sauk Rapids, and Rice.
Most tornadoes do not kill and only cause minor to moderate damage. However, in the worst cases, a tornado can destroy entire towns and kill dozens. A few tornadoes have had death tolls in the hundreds.
The most dangerous tornadoes are those rated F5 or EF5. Perhaps the most dangerous situation is that of a large, fast-moving EF5 tornado that is obscured by rain and/or clouds. These factors have contributed to very high death tolls in some tornadoes.
Usually none. A survey of tornadoes in the late 20th and early 21s centuries show that only about 2% of tornadoes in the US ever kill anyone. Of the tornadoes that do kill, most only kill 1 person. Tornadoes with death tolls in the dozens are rare.
Tornadoes can effect people in many ways. Tornadoes they can result in property loss, injuries, and death. Many tornadoes occur throughout the year but only a small percent, actually do a large amount of damage. Homes, farms, and businesses can be damage or destroyed. In some of the worst tornadoes entire towns have been destroyed. Only about 2% of tornadoes kill and most of those killers only claim 1 or 2 lives. However in rare cases death tolls can rise into the dozens, and a handful have had death tolls in the hundreds. Hurricanes have similar effects, but the damage is more widespread and thus cost of damage is often higher than that of a tornado, even if damage in any given location is less severe. However in cases such as Hurricanes Ike and Katrina, entire neighborhoods may still be washed away by the storm surge. Hurricanes can also have higher death tolls than tornadoes, with some killing thousands.
No. Hurricanes are generally deadlier. There have been a number of hurricanes with death tolls over 1,000 but only one known tornado holds that distinction.
No. While F3 tornadoes can be deadly they are not the deadliest. F5 tornadoes are the most destructive and generally the deadliest. The highest death toll from an F3 tornado in the U.S. since 1950 was 25, compared with nine F4 and F5 tornadoes with death tolls upwards of 50 of which three (all F5 or EF5) killed more than 100 apiece.
Official record keeping for tornadoes in the U.S. began in 1950. Annual tornado death tolls are available as far back as 1875, though their accuracy is not as great as it is for years after 1950. Other data is hit-miss.
There were 33 confirmed tornadoes in Iowa in 2010.
In The average tornado there are no deaths. On average the U.S. gets over 1,200 tornadoes per year but only about 60 tornado deaths. The average death toll for a killer tornado (at least for the U.S.) is between 2 and 3, but this is skewed upwards by a handful of tornadoes with large death tolls. The typical death toll for a killer tornado is 1.
There were 88 tornadoes in Kansas in 2010.
