Ok,heres an example of what I am talking about as far as fault line lights and activities..

Persinger and Lafrenière saw UFOs as electromagnetic phenomena arising from the tremendous energy associated with the constantly rising and falling tectonic stress in the Earth's crust, whether or not full-blown earthquakes occurred. They visualised fields of forces operating evenly and quietly over large regions which could become focused at any given time in a few small areas of particular geological resistance or instability such as fault lines, mineral deposits, unyielding rock outcrops, hills, mountains and so on. They likened this to the energies in the atmosphere being equally capable of producing a gentle breeze over a wide area or a localised ferocity like a tornado. "The existence of man upon a thin shell beneath which mammoth forces constantly operate, cannot be over-emphasised," they argued. This was the first outing of what has come to be known as the Tectonic Strain Theory, or TST.
Successive reporting of lights occurred in the seven months preceding the biggest earthquake of the studied period. Regional seismic activity also increased during the times in 1972 and 1976 when most sightings were reported. (The irony of the Yakima case is that the reservation is adjacent to the part of the Cascades Mountains where pilot Kenneth Arnold saw the flight of nine glittering objects in 1947 that initiated the flying saucer era. In fact, Arnold landed his plane at Yakima airfield shortly after his
encounter.)
But it was the outbreak of lights at Hessdalen, a valley 70 miles (112km) south-east of Trondheim in Norway, that really switched on the earth lights.
>From about November 1981, people living in the mineral-rich area began
seeing unexplained lights. These appeared as white and yellow-white spheres, 'bullets' with pointed end downwards and inverted "Christmas tree" shapes.
Strong, localised flashes in the sky were also observed and there were reports of underground rumbling. By the summer of 1983, hundreds of reports of strange lights had been made by the inhabitants of Hessdalen, so Norwegian and Swedish UFO groups formed Project Hessdalen. From 21 January to 26 February 1984, the project continuously monitored the valley using a range of instrumentation, including radar, and succeeded in obtaining photographs of strange lights plus a number of instrumental readings. Such work then continued sporadically over a few years.

I think what occurs in these instances is not due to one thing,but in fact by several.One might be cause by static or releasing energy above a fault or hydrogen.Either way,they are beautiful and we are lucky that things like this happen for us to see.
