Every year in the United States, tornadoes do about 400 million dollars in damage and kill about 70 people on average. Extremely high winds tear homes and businesses apart. Winds can also destroy bridges, flip trains, send cars and trucks flying, tear the bark off trees, and suck all the water from a riverbed.

Has there ever been an F12 tornado?
An F12 tornado would have winds of about 740 MPH, the speed of sound. Roughly 3/4 of all tornadoes are EF0 or EF1 tornadoes and have winds that are less than 100 MPH. EF4 and EF5 tornadoes are rare but cause the majority of tornado deaths….

When did tornado damage increase in the US?
There has been a large increase in tornado damage rated F0 since 1970. This is especially evident during the late 1980s when there was a reversal in the ratio of F0 to F1 rated damage. In the 1970s, there was more damage caused by tornadoes rated as F1 than by other Fujita categories.
When was the peak in number of tornadoes?
In the 1970s, there was an average of 858 tornadoes per year. In the 1990s, this increased by almost 30% to an average of a little over 1200 tornadoes per year. While the peak in tornado frequency in the early to middle 1970s included the 1974 Super Outbreak, the year with the most tornadoes during that span was 1973!
What was the average number of tornadoes per year in the 1970s?
