AbstractNatural Resources Canada was asked for assistance by the Ontario Ministry of the Environment in their ongoing investigation of rumblings" reported in Essex County, Ontario. Reports of the rumblings which appear to be a combination of vibrations and low frequency noise began in March 2011 and are continuing as of this writing (September 2011). In June 2011 four seismometers were installed in the western part of the city of Windsor where the largest number of noise complaints originated. The stations ran until late August 2011. Examination of the data revealed a signal on two of the stations that was consistent in character with the reported rumblings in terms of time, duration and behavior. Further analysis of the signals revealed that they were propagating as acoustic waves in the atmosphere and that they originated from the general vicinity of Zug Island, Michigan. Further investigation is required to determine the exact source of the signal.
