The earthquake was felt over an area of 30,000 square miles.[2] In Terre Haute, the earthquake toppled two chimneys, cracked plaster, and knocked pictures from walls. Nearby Covington, north of Terre Haute in Fountain County, experienced several fallen chimneys and some broken windows. Chimneys were "jarred loose" in Princeton, Indiana, and one chimney was even "shaken to pieces" at Olivette, Missouri (a suburb of St. Louis). A brick wall was also "shook" down within St. Louis, Missouri. Reports came from various states, including Arkansas, Illinois, Iowa, Kentucky, Ohio, and Tennessee.[3]
