Q: (L) Why are UFOs frequently sighted over geological fault lines?
A: Electromagnetism. Use electrical free waves as fuel for power restoration.
Q: (L) Could it be that the UFOs are a manifestation of the geomagnetic energies emitted at fault lines?
A: No. Not all theories are correct and some are not even sincere.
Q: (L) What is the connection between UFOs and earthquakes?
A: Is none. Coincidence. If they are there, some fault breaks produce EM fields which are visible briefly as red or yellow light flashes.
