Are nocturnal lights earthquake lights?
"Nocturnal lights reported from 1972 to 1977 by fire lookouts on the Yakima Indian Reservation, Washington, correlate with earthquake origin time, distance, magnitude, and depth within a 200 km radius of the observations. Photographs and eyewitness accounts show that the luminous phenomena (LP) near ground level appear to be spherical, are colored white to orange, and show little or no internal detail. Locations of the observations preclude explaining them as terrestrial vehicles or other human activity."
This abstract continues and notes that some of the luminous displays seem to be enhanced by geomagnetic activity.
