major damage in some neighborhoods. The flooding was just as bad in Blackberry Creek, on Aurora's far west side. Aurora has not been struck by any major tornadoes in recent history, although they occur in Northern Illinois annually. In 1906, a tornado went through the Aurora Driving Park, a large recreation/amusement park and race track where the Riddle Highlands neighborhood and Northgate shopping center is today. The tornado hit during the afternoon performance of the Ringling Brothers "Greatest Show on Earth" circus, when the park was crowded. It killed 2 people and injured 22, but the grandstand was still filled for the evening performance. Weak tornadoes struck the city in 1954, 1958, 1960, and 1991. In 1990, the supercell thunderstorm that produced the deadly Plainfield Tornado passed over the city, dropping golf ball sized hail and causing wind damage. Less than ten minutes after passing through Aurora, the storm produced an F5 tornado, which touched down in nearby Oswego, less than 5 miles from downtown. The tornado then traveled through Plainfield and Joliet, killing 29 people. The city can receive heavy snowfall and experiences blizzards periodically. Aurora was hit with one of the strongest earthquakes ever to strike Illinois, a M 5.1, on May 26, 1909. It put cracks through chimneys and could be felt around.
