Anna is a village in Shelby County, Ohio, United States.

The prehistoric Teays River ran through modern-day Anna about 2 million years ago.

The Teays river deposited loose sediment on the Greenville fault line which created a major earthquake center.

[citation needed] According to the Native Americans, Tecumseh tried to start his alliances in what is now Anna.

The shaking followed a similar but somewhat weaker event that had happened a week earlier, on March 2.

The partially damaged school became a total loss for the town and had to be rebuilt.

The town hall was so badly damaged that the upper story was condemned and has not been used since.

19.6% of all households were made up of individuals, and 6.3% had someone living alone who was 65 years of age or older.
