It's a fucking scam. Like santa claus, the easter bunny, and puppies.
Earthquakes lights have a scientific base , and its simple if you think
tectonic plates causes earthquakes, there is a hge amount of energy moving such big mass, the core of earth is constantly trhowing particles of any type in surface, most of them are of electromagnetic nature, when the flux of these particles reaches high in the atmosphere it interacts with clouds and magnetic earth fields, the lights are interference pattern beetween earth's magentic field and stream of particle coming form the nucles of the earth.
Its physics, just do 2 + 2 ..well , if you have studied em fields, microwaves, propagation fields, physics 2 ,chemistry , electrotechnics I and II , or it will apperas as an hoax...
Interesting about those clouds..
