Colorful light flashed in Mexico's strongest earthquake

Unidentified glares constantly flashed in the night sky in Mexico between the strongest earthquake in 100 years in the country.

The spectacle of the sky appeared many bright lights in Mexico City, Mexico, while the magnitude 8.1 earthquake shook the country last night by many witnesses, according to Fox News.

The light rays were white, pink, green, blue, shining brightly above the tall buildings, sparking a lot of speculation on social networks. The online community offers many theories to explain their origins, from thunderstorms, phenomena related to the Sun and even reflection from the lights in the city.

One possible explanation is the earthquake light, the rare flashes in the sky that occur during the earthquake. According to National Geographic, a 2014 study by scientists showed this light due to the discharge of some rocks.

Light can sometimes take on many different shapes and colors, according to Friedemann Freund, assistant professor of physics at San Jose University and senior researcher at the Ames Center of the US Aeronautics and Aeronautics Agency. (NASA).

Previous theories suggest that the above light may be the result of the Earth's magnetic field being interrupted by pressure on the plate. But Freund disagreed. " When nature puts pressure on some rocks, the charge is activated as if you turned on a battery in the Earth's crust ," Freund said.

Basan rocks and gabbro stones are thought to be able to discharge because they have small defects in the lattice and collide with seismic waves, which can release the charge.

These are many types of rocks found in structures along the underground in some places. The charge can combine and form a plasma-like state, which can travel at very high speeds and explode on the ground to discharge electricity into the air to create an impressive series of flashes.
