As a 7.0 earthquake shook Mexico's Acapulco, night sky lit up with hues of green, purple and yellow that are called 'Earthquake Lights'.

The video shows the night sky during the quake that was lit up by bright purple, green and blue hues known as ‘Earthquake Lights’. The mysterious lightning of the night sky reminded people of the time when a magnitude 8.1 earthquake struck Mexico in 2017, as similar images and videos had gone viral on social media. While it stunned people around the world, many locals said it has become a common sight during quakes in the country.

The lights can take “many different shapes, forms, and colors,” Friedemann Freund, an adjunct professor of physics at San Jose State University and a senior researcher at NASA’s Ames Research Center, said in a 2014 National Geographic interview. Explaining the rare phenomenon the report added that “the lights are caused by electric charges activated in certain types of rocks during seismic activity, ‘as if you switched on a battery in the Earth’s crust’.” According to scientist the earthquake lights more commonly appear before or during quakes, not as much afterward.
