    May 6, 1947

    A very strong earthquake shook a 3,000 square mile area in southeastern Wisconsin on May 6, 1947, but caused little damage. The quake was of short duration and was felt as a “heavy bump” in some localities, and as a quick, sideward shift of the earth in others. The earthquake was felt from Sheboygan to the Wisconsin-Illinois border and approximately 25 miles inland from Lake Michigan.
