"Earthquake Lights"

 
Hi John and Doves,
 
Inasmuch - I spent quite a bit of time researching earthquake lights. The scientists have 'theories' but they are certainly not sure what these lights are, or what causes them. The other factor, adding to their mystery, is that they don't occur before every earthquake. They are not consistent with every single earthquake. Here is but one link:-
