a An earthquake measuring 7.1 on the Richter scale struck Acapulco, Mexico. It shook that population on Tuesday night. With this move, however, the damage assessment has been done so far, soCurious blue lights appeared at various places that lit up the sky.
people, quickly on social networks, as well as notification of shocks, He uploaded photos and videos of these flashes, which are produced when tectonic plates move with force and generate an electromagnetic discharge.
“There are some flaws in the rocks of the earth’s crust and They release electrons or electric charges when subjected to this friction.”, said Professor of the Institute of Geophysics (IGf) of UNAM Esteban Hernandez in an interview with the EFE agency in 2017.
Science explains this phenomenon by saying that when there are small imperfections in the crystals of the earth’s crust such as basalt and gravel, and The seismic wave collides with the tectonic layers causing friction to emit electrical charges that these light generate in the sky.
natural phenomenon is called triboluminescence Or earthquake lights and various earthquakes from the 1600s have been documented in the scientific literature.
“In some cases the telluric movement makes the cables oscillate and in some cases the light poles“A very large spark that causes a kind of short circuit, which causes the light to appear in this way,” said the expert.
These were some of the videos shared on the social network:
