The longest tornado pass is a tri-state tornado on March 18, 1925, with a path length of 215 miles. It is 7 hours 20 minutes on the ground. Because no damage report has been submitted, it is difficult to know whether the tornado actually stood on the ground or it is the result of some tornadoes. The shortest tornado reported was 7 feet long. On May 3, 1999, Mobile Doppler radar was 100 feet high and reported twists at wind speeds up to 302 mph, or ± 16 mph. Scientists have discovered that the strongest wind usually occurs about 300 feet from the ground. However, most tornadoes have wind speeds below 11 3 mph.

The worst and most powerful tornado in the US took hundreds of lives. On March 18, 1925, three outbreaks occurred in three states: Illinois, Missouri and Indiana, and 740 people died. Another deadly tornado in the US was a super explosion from April 3 to April 1974. It killed 315 people from North Alabama to Ohio and produced 148 tornadoes

Three-state tornado on Wednesday March 18, 1925 was the most deadly tornado in American history. It is also the most special tornado between at least 12 known major tornado occurrences spreading to the greater part of the Midwest and South of the United States. This time 695 people were killed by a tornado, more than twice the number of times the second deadly tornado occurred on the Mississippi River on May 7, 1840. The tornado left a trajectory of 151 to 235 miles (243 to 378 kilometers) as the longest record recorded in southeastern Missouri, southern Illinois and southwestern Indiana. NOAA has no official rating, but most experts (such as Tom Grazulis and Ted Fujita) think that it is an F5 tornado. This is the highest damage level released on the Fujita scale.
