Abstract
Multiple regression analyses were used to test the hypothesis that UFO (unidentified flying object) reports are indices of natural events associated with accumulating tectonic strain within the earth's crust. More than 80% of the variance in a sample of UFO report numbers within the central and eastern U.S.A. between the years 1950 and 1966 could be accommodated by entering the appropriate three to five measures of geomagnetic or seismic activity of the previous one to three years. In general, UFO report numbers tended to increase two to three years after decreases in geomagnetic activity and the year after increases in the number of local, low intensity earthtremors. Predicted UFO report numbers within these regions were also determined from the equations for the years 1967–1981.
