Recently, 24/7 Wall St. reviewed government sources on the weather event in each state’s history that caused the highest number of fatalities to determine the worst natural disaster in every state. You might naturally think that a significant tornado would be the worst natural disaster in Indiana, but surprisingly, that's not the case.

The Worst Natural Disaster in Indiana's History

According to 24/7 Wall St., the worst natural disaster in Indiana's history was the Great Flood of 1913. This event took place in March of 1913. Several unfortunate events led to the flood including a windstorm, a cyclone, and severe rainfall. According to the Indy Star:

Flooding left the Wabash River nearly seven miles wide. It averaged 5 to 7 feet deep between Vincennes and Lawrenceville, Illinois. While there was no official county, the death toll in Indiana is estimated between 100 to 200.

Not only did this flood affect Indiana but several other states as well. Dayton, Ohio was probably the most affected. The History Channel says that it's estimated that the Great Flood of 1913 killed more than 1,000 Americans, making it the country’s second-deadliest deluge (behind only the 1889 Johnstown Flood, in which more than 2,200 lost their lives).

24/7 Wall St. did mention that the other event considered to be the worst natural disaster in Indiana's history was the Tri-State Tornadoes of 1925. You can learn all about that event in Indiana history by clicking here.
