More Indiana tornado stuff

[Hoosier]

I wanted to see what the tornado totals were for each county so I used the NCDC Storm Events database and Severeplot 3.0 to construct this map. It is the number of tornadoes per 100 square miles per county from 1950-2010.

Not surprisingly, population bias is pretty noticeable. It's not a perfect relationship but there is a general tendency for higher populated counties to report more tornadoes.

Here are the top 5 counties in terms of tornadoes per 100 square miles:

Marion - 10.35

Tippecanoe - 8.40

Vanderburgh - 7.67

Shelby - 7.03

Elkhart - 6.90

Here are counties ranked by population. Notice that 4 of the above listed counties appear in the top 8 (out of 92) in terms of population. Curiously, Shelby county ranks much farther down on this list.

1. Marion

2. Lake

3. Allen

4. Hamilton

5. St. Joseph

6. Elkhart

7. Vanderburgh

8. Tippecanoe
