@scienceactually Not buying it:

The U.S. Geological Survey is circumspect about whether earthquake lights, or EQL, really exist. "Geophysicists differ on the extent to which they think that individual reports of unusual lighting near the time and epicenter of an earthquake actually represent EQL," the agency says on its website. "Some doubt that any of the reports constitute solid evidence for EQL, whereas others think that at least some reports plausibly correspond to EQL."
