4.0 Youngstown Akron earthquake Ohio December 31 2011 The United States neutrino detector is 2000 feet underground in a salt mine near Fairport, Ohio (slightly east of Cleveland). The detector is the collaborative effort of the Proton Decay Group of the University of Michigan, the University of California (Irvine) and the Brookhaven National Laboratory. The detector is 10,000 metric tons of highly purified water. In this pool are 2048 extremely sensitive light-detecting photo multiplier tubes. These tubes uniformly cover the walls, floor and ceiling of the totally enclosed pool of ultra-pure water that measures approximately 80' x 70' x 70'.
