Recent research, mostly from Japan and China, adds evidence to support the idea that earthquake lights are a result of electrical interactions between the lithosphere and the atmosphere.
Social media accounts shared video of “earthquake lights” that appeared near Delhi, India after the Hindu Kush quake on 21-March. But the lights were not what was described in the media. They were, instead, reflection of nearby commercial lights on clouds.
The evidence for earthquake lights (EQLs) consists overwhelmingly of anecdotal accounts. But scientific evidence has been accumulating, and in the past 10 years a plausible theory to explain the host of unusual precursors has been proposed. This comprehensive guide examines the credibility and causes of earthquake lights.
