Where has the most destructive tornado occured give details about the tornado?

Answer 1

There are two candidates.

On official records the most destructive tornado was the F5 that hit the Oklahoma City area on May 3, 1999. The tornado killed 36, injured 583, and caused about $1 billion in property damage. The damage path was 38 miles long and 1 mile wide. Doppler radar measured winds over 300 mph in this storm at a height of about 100 ft, the fastest ever recorded on this planet. The tornado first touched down south of Amber, Oklahoma and moved into the town of Bridge Creek where the first of the catastrophic damage occurred. The tornado then moved back out into open country before hitting the OKC area. The worst damage was in the suburb of Moore, where the tornado struck at peak intensity. It then turned to the north, continuing its trail of destruction before dissipating near Midwest City.

The other candidate is unofficial as data is not yet finalized. This was the EF5 tornado that hit Joplin, Missouri on May 22, 2011. This tornado killed at least 158 and injured over 1,000, marking it as the 7th deadliest in U.S. history. Damages is estimated at $1-3 billion. The damage path was 22 miles long and 3/4mile to 1 mile wide. The tornado touched down a few miles west of Joplin and grew and intensified at an explosive rate. By the time it hit Joplin it was already a very strong tornado and was still gaining strength. The tornado reached peak intensity as it passed just south of downtown Joplin with ground level winds estimated at 225-250 mph. The tornado then weakened before leaving the city, but continue to produce damage to farms and trees before dissipating some distance west of the city. When the storm was over 1/3 of Joplin was destroyed.
