Several videos on social media have surfaced from Morocco showing a blue flashlight emanating from the horizon, shortly before a potent 6.8 earthquake which struck southwest of Marrakech last Friday, leaving nearly 3,000 people dead and over 3,000 injured.
Rescue mission by a number of countries in the North African nation is currently underway as emergency services are searching rubbles for bodies and survivors.
Earlier, a French expert also issued warnings about the aftershocks, despite the country not being in the "most active seismological region".
CCTV on social media showed powerful flashes of light just before the shaking. Experts have termed these luminous phenomena real however, they are still scratching their heads about what causes them.
John Derr, a retired geophysicist who worked at the US Geological Survey told CNN that these different colours of lights are definitely real.
"Seeing EQL depends on darkness and other favorability factors," Derr, who worked on these earthquake lights explained.
He said the recent "video from Morocco shared online looked like the earthquake lights caught on security cameras during a 2007 quake in Pisco, Peru."
Juan Antonio Lira Cacho, a physics professor at Universidad Nacional Mayor de San Marcos in Peru and the Pontifical Catholic University of Peru, who has studied the phenomenon, said video and security cameras have made studying earthquake lights easier.
