Did you know that a factory foreman reported seeing a ball of light "about the size of 20 suns" during the 1911 Ebingen earthquake (drawing pictured)?
An earthquake light, also known as earthquake lightning or an earthquake flash, is a reported luminous phenomenon that is said to be associated with tectonic stress or seismic activity. Reports describe flashes, glows, luminous orbs, sheet-like lights, streamers, and other transient lights observed before, during, or after earthquakes and at varying distances from earthquake sites. Experts differ on whether the reports describe a single real phenomenon, multiple unrelated phenomena, or misidentified natural and artificial light sources, and there is no consensus on a confirmed geological mechanism.
