The St. Louis tornado was the costliest tornado in U.S. history, causing approximately $2.9 billion in property damage in today's dollars.
The tornado struck Bangladesh, killing an estimated 1,300 people, making it the deadliest tornado in history.
This 1999 tornado had the largest wind speed estimate in history at up to 318 mph.
As such, tornadoes are not only extremely dangerous in their own right, but they also turn anything that is blown around by their high wind speeds into a missile.
Broken windows, broken trees, and maybe even bricks or cars can be turned into weapons by a tornado. Tornadoes cause damage to almost everything around them.
Therefore, tornado preparedness should be widely publicized, and efforts should be made to improve forecasting methods to minimize its damages. In particular, various studies are needed to communicate tornadoes to rural and farming areas where information about tornado is difficult to obtain.
