Prediction of historical and contemporary luminosity (UFO) reports by seismic variables within Western Europe

  • M. A. Persinger
Full Papers


Changes in tectonic strain within the earth's crust have been hypothesized to be the primary energetic source for most documented UFO (unidentified flying object) reports. Discriminant and multiple regression analyses indicated that seismic variables that correctly classified and predicted years that contained reports of spectacular spherical luminous phenomena during the 19th century, also correctly predicted major UFO episodes during the present century. The results indicate that phenomena once labelled as odd luminosities, mysterious airships and phantom airplanes in previous decades are associated with UFOs now.

    Earthqake data for the years 1820 to 1975 (end of file) were sorted from the Mayer-Rosa file (#4); it was obtained through the Environmental Data Service at Boulder, Colorado. Data for the years 1976 to 1980 were obtained directly though the courtesy of Dr Dieter Mayer-Rosa, ETH-Hönggerberg, CH-8093 Zurich, Switzerland.Google Scholar

    The predicted values were calculated by multiplying the partial regression coefficients for each variable times the value for the variable (the number of quakes or percentage change measure of the appropriate intensity), adding them according to the valence of the coefficient and then adding the constant. The computed values were verified with the predicted values produced by the original regression equations for the years 1870 to 1910.Google Scholar

    Contemproary UFO report data for the countries selected for this analysis were obtained from different data sources that included: APRO (Aerial Phenomena Research Organization), Fate Magazine and Flying Saucer Review. Data pools for the years 1946 to 1979 were checked for case redundancies; separate analyses were completed for different types of UFO reports, with special emphasis on those most similar to SLP. They comprised more than 80% of the entries from these data sources.Google Scholar
