How many tornadoes do we have a year?
Question Date: 2005-12-08
Answer 1:

Tornadoes occur in many areas around the world but no region experiences more tornadoes than the central United States. No one really knows for sure how many there are in the US each year, but it is estimated that over 1,000 tornadoes occur each year in the US, although many go undetected and unreported. The States that are hit the most are Alabama, Arkansas, Florida, Georgia, Illinois,Indiana, Iowa, Kansas, Louisiana, Mississippi, Missouri, Nebraska, Oklahoma,South Dakota, and Texas. (Oklahoma itself has about 52 tornadoes occur on average each year).

Besides this region, portions of western Europe are perhaps most notably at risk. In the British Isles, an there is an average of 10 tornadoes per year. In Austria, about 2.6 tornadoes are recorded each year.
