Why did the sky light up during the earthquake in Mexico? | Digital Trends Spanish

A violent 7.1 magnitude earthquake struck Mexico City and several nearby towns on the night of this Tuesday, September 7.

The earthquake would have occurred 11 kilometers southwest of Acapulco, Guerrero, southeastern Mexico, according to the National Seismological Survey and, so far, one fatality has been registered.

In social networks there are many videos that show panic among people and despair when trying to find shelter against the strong movement.

Another thing that has attracted attention in the records has been the great variety of lights of different colors that illuminated the night sky of the Mexican capital during the earthquake.

Many were surprised by this effect, since it is about red, blue and green lights that could be observed in different parts of the sky that covers the city.

The movement coincided with the rain that fell on Mexico City at that time, therefore, many thought that the lights could be related to lightning or an electrical storm. However, it was the local authorities themselves who ruled out this possibility.

According to the Institute of Geophysics of the National Autonomous University of Mexico (UNAM), this striking phenomenon is known as “earthquake lights” and is produced because the rocks of the earth’s crust have imperfections in their crystals and thus, when a wave seismic moves them, friction causes the electrical charges of the rocks to be released.

Subsequently, these charges come together and shoot towards the surface at high speed, manifesting in the sky.

These are some of the videos:

I hope you are all well 🖤
It seems that it is already a tradition of September… 🙄

So the panoramic of Mexico City at the exact moment of the earthquake tonight! 🚨

A hug to all!
