22 Miraculously Awesome Rare Natural Phenomena That Occur on Earth

19. Earthquake Lights
Location: Just before an earthquake.

An earthquake light is an unusual luminous aerial phenomenon that reportedly appears in the sky at or near areas of tectonic stress, seismic activity, or volcanic eruptions. The lights are reported to appear while an earthquake is occurring, although there are reports of lights before or after earthquakes. Many hypotheses have been proposed for the explanation of the phenomenon, but no clear explanation exists as such. For instance, The most recent model suggests that the generation of earthquake lights involves the ionization of oxygen to oxygen anions by breaking of peroxy bonds in some types of rocks by the high stress before and during an earthquake. After the ionisation, the ions travel up through the cracks in the rocks. Once they reach the atmosphere these ions can ionise pockets of air, forming plasma that emits light.
