Mysterious green and blue flashes were seen by witnesses in Mexico City after it was rocked by a magnitude 8.2 earthquake.
The powerful quake set off a tsunami warning for at least eight countries – and at least six people have been confirmed dead in the most powerful quake to strike the country for 100 years.
A video of the earthquake lights was captured by a witness – capturing a strange, little-understood phenomenon.

Earthquake lights have been reported around the world for decades – with some claiming it’s a natural phenomenon, and others claiming it’s due to structural damage.
Seismologist Stephen Hicks said: ‘Earthquake lights have never been proven. Simpler explanation is small explosions in electric generators and power systems.
Reports of strange lights during earthquakes are common – sometimes even before the quake.
Some have suggested that the lights might be caused by electrical transformers or small explosions near the site of a quake.
A scientific paper in Seismological Research Letters suggested that charged atoms near the surface of the Earth may be behind the phenomenon – ionising pockets of air which form light-emitting plasma.
The paper suggested that the lights are sometimes seen weeks before an earthquake strikes.

Bizarre lights spotted in skies above Mexico City during quake
Friday’s 8.2-magnitude quake in Mexico caused a rare phenomenon known as earthquake lights in skies above the capital city.
The lights could be seen flashing above Mexico City in hues of greens and white. Video uploaded from the scene shows the dramatic display.

A 2014 study said the stress of the tectonic plates can break apart pairs of negatively-charged oxygen atoms, pushing them towards the Earth’s surface and forming a light-emitting plasma when it combines with air.
A tsunami warning is in place following Friday’s earthquake, the strongest in a century. At least five people are reported dead with the number expected to rise.
