Geophysical Variables and Behavior: LXXIV. Man-Made Fluid Injections into the Crust and Reports of Luminous Phenomena (UFO Reports)—Is the Strain Field an Aseismically Propagating Hydrological Pulse?

According to the tectonic strain theory, both earthquakes and most reports of UFOs (Unidentified Flying Objects) or odd luminous phenomena are generated by local transient changes in regional crustal stress. Because the injection (or containment) of fluids or their percolation into the upper crust can trigger earthquakes, we predicted that reports of these anomalous luminous phenomena should display temporal lags and spatial diffusion around these sites. The hypothesis was supported around the five test sites of Derby, Colorado; Attica, New York; Rangely, Colorado; Sanford (Amarillo), Texas; and Hanford, Washington. The results support the hypothesis that luminous phenomena, often described by the contemporary label of UFOs, are associated with natural hydroseismicity and can be initiated by man-made activity.
