Mexicans are sharing spectacular videos of bursts of blue lights seen streaking across the skies as a strong earthquake rocked the country's Pacific coast city of Acapulco on Wednesday.
The 7.0 magnitude quake struck some 11 miles northeast of the resort city in the southwestern state of Guerrero.
At least one person was killed, buildings were damaged and rockslides littered a major highway - but the temblor didn't cause widespread damage.
Felt some 200 hundred miles away in Mexico City, and lasting nearly a minute, residents fled into the streets as buildings swayed, sidewalks undulated and the blue lights burst brilliantly in the sky.

(21,627 posts)According to a local geological engineer, "this luminescence is due to the disturbance of the electromagnetic field that surrounds the Earth as a result of piezoelectric currents generated by compression of silicates."
But ¿quién sabe?
Who knows.
That said, it's good to hear that loss of life and damage were relatively minimal. Nothing like the 1985 quake, thank goodness.
