All of these earthquakes have been felt in Milwaukee either as reported in the Milwaukee Journal and Milwaukee Sentinel newspapers, or, for the more recent quakes, as reported to me in telephone and email contacts. There is only one earthquake, on this list, that actually occurred in the Milwaukee area. That was the earthquake of May 6, 1947. There are a number of other earthquakes that probably were felt in Milwaukee but I have not been able to find recorded histories for some of the early events, most notably, the series of very large New Madrid earthquakes that occurred in the winter of 1811 - 1812. In recent times, there has been some local, Milwaukee, events that were initially considered to be small earthquakes but, in retrospect, are now considered to be sonic booms or other man-made vibrations.
