Abstract
This study provides the first quasi-experimental evidence for the Tectonic Strain Theory for luminous phenomena. Approximately 1500 earthquakes occurred near Derby, Colorado during the years 1962 through 1967 as a result of injection of several millions of gallons of industrial waste fluid into the crystalline bedrock. Correlations between numbers of luminous phenomena within successive 100-km rings from the injection site and the release of seismic energy gave significant coefficients for distances as great as 400 km. Lag/lead analyses between the monthly volume of fluid injection and the monthly numbers of luminous phenomena at various distances indicated that some process was diffusing away from the injection site at a rate of 50 to 100 km/month to distances as far as 300 km. Partial correlation analyses supported the hypothesis that both the luminous phenomena and the Derby quakes were generated by the stresses evoked by the amount of fluid injection during that period. Unprecedented increases in luminous phenomena occurred before releases of strain energy that exceeded magnitudes of 1017 ergs/month.
