Mexico, the most powerful earthquake of the last 100 years, seismic lights in the sky

The most powerful earthquake of the last 100 years comes just before midnight, when Mexico City, a colossus of a thousand neighborhoods and with 20 million inhabitants, began to face the night. Many witnesses reported that monstrous noises came from the earth. The tension and stress can still be read in the eyes and legs of the people who are still on the street, incredulous of the power of nature. These are not easy moments, impossible to forget, in which all the neighborhoods seemed in a panic. The population witnessed another strange phenomenon: the earth trembled under their feet, while 'above', in the sky, you could see a strange sparkle ". A phenomenon that has an explanation, as reported by the experts cited immediately after the violent earthquake by the local media: they are electromagnetic alterations that produce seismic lights. Everything 'normal', therefore, or almost. Araceli, 51, lives in Xochimilco, a tourist and lake area in the south of the capital, also known as' La Venecia Mexicana ”. For her this is certainly not the first shock of her life: “it doesn't matter, I had never felt the earth move like this, that's why I was afraid”. Not far away, in Los Cipreses, lives Rosa, a 54-year-old lawyer, who in those terrible moments sought refuge in the faith: "God protect us", she still only says now. And the lights in the sky ?: “Yes, I saw them, it seemed the end of the world”. On a nightmarish night like that of this Thursday marked by 'an 8,2 Richter' of similar stories there are thousands of them, all of them moreover citizens who know about earthquakes, because they have witnessed other shocks: Mexico it is not Chile, but it remains a country with a very high telluric rate. Just think of another mega-earthquake, that of 19 September 1985. Same intensity as today, but that time the dead were 15.

Seismic lights

According to a study published in the journal Seismological Research Letters, and led by researchers, led by Canadian geologist Robert Thériault, the seismic lights, called Eql, are linked to a rapid accumulation of energy trapped between the faults of the subsoil. These induced electric currents flow to the surface through cracks in the ground where, once ionized together with the air molecules, they generate luminosity. Lights can take on a variety of shapes, the main ones being spheres that are stationary or floating in the air.
