It’s a bird, it’s a plane, it’s … an earthquake?
For hundreds of years there have been reports of strange lights during earthquakes, now scientists are trying to figure out what they are
The reports read like science fiction: “Fireballs a few meters in diameter often popped out of the ground in a repetitive manner at distances of up to only a few meters away from the observers.” These observers may sound crazy, but they’re not. They’re actually describing a real phenomenon called earthquake lights. Scienceline talks to David Brumbaugh, director of the Arizona Earthquake Information Center about these lights and what might cause them.
