Mexico City /
September arrived accompanied by a powerful earthquake of 7.1 degrees in the scale of Richter with epicenter to 11 kilometers to the west of Acapulco, which generated alarm especially between the population of the Mexico City, Although it was also felt strongly in the states of Michoacán, Veracruz, Morelos and Oaxaca.
During the earthquake they could be seen colored lights in the sky, Which increased the stupor among the inhabitants, although it is a phenomenon that happens occasionally when trembles during the nights. It is also caused by damage to the electricity grid.
A possible reason
Just four years ago, when an 8.2-magnitude earthquake hit especially the coast of Oaxaca near midnight, the electrical phenomenon also occurred and since then a scientific explanation of a possible why was divulged.
According to a study by the Rutgers University, In the United States, which was picked up by the chain BBC, “The bioluminescence effect is due to the fact that landslides near the geological faults of the earth generate an electric charge“.
However, the researchers clarified that it is not always given.
“We found that they appear to be the precursors of some great earthquakes, Of magnitude 5 or greater. But the voltage signal is not always the same. Sometimes it’s high and other times low, ”Troy Shinbrot explained, during the 2014 meeting of the American Physical Society, by biomedical engineer Troy Shinbrot.
