Mexico earthquake causes flashing lights and power outages
Flashing lights were seen in a neighbourhood in Mexico City as a magnitude 7.0 earthquake hit near port city Acapulco on September 7 evening.
Footage shows the 'earthquake lights' sparking on the horizon near the neighbourhood of Buenavista late Tuesday. Commotion filled the streets as locals fled from their houses.
Mexico City Mayor Claudia Sheinbaum said the tremors caused power outages which authorities were working to restore.
The United States Geological Survey said the strong quake was shallow, measured at an initial depth of 7.8 miles below the surface. Its effects were felt as far as 230 miles away from the epicentre.
Authorities said there has been one casualty so far — a man crushed by a falling post in a small town west of Acapulco city.
Earthquake lights reportedly occur during notable seismic activity. The contentious geophysical phenomenon has yet to be explained definitively by scientists, with conflicting theories emerging over what exactly causes them.
