Mexicans who reported bizarre flashing lights in the sky during last night's earthquake believe they could have been caused by UFOs - or even the apocalypse.
The country was struck by an 8.1 magnitude earthquake after a massive tremor hit in the Pacific Ocean near the border of Mexico and Guatemala yesterday.
The shock was felt as far away as Mexico City and across Central America.
Some of those watching the earthquake unfold noticed strange green lights flashing in the sky during the tremors.
Within minutes of the videos appearing on social media, people had started speculating as to the possible causes of the luminous phenomenon.
