CNN —Reports of “earthquake lights,” like the ones seen in videos captured before Friday’s 6.8-magnitude earthquake in Morocco, go back centuries to ancient Greece.
He has coauthored several scientific papers on earthquake lights, or EQL.
To better understand earthquake lights, Derr and his colleagues gathered information on 65 American and European earthquakes associated with trustworthy reports of earthquake lights dating back to 1600.
Other theories about what causes earthquake lights include static electricity produced by the fracturing of rock and radon emanation, among many others.
At present there is no consensus among seismologists on the mechanism that causes earthquake lights, and scientists are still trying to unlock the mysteries of these outbursts.
