At around 1:04 am on Sunday, May 14, an earthquake shook the central region of the country. Strong telluric action of 5.0 with an epicenter in AcacíasMeta, however, this was felt in many cities, including Bogotá.
Initial information from the Colombian Geological Service indicates that the earthquake had a superficial depth, that is, 30 kilometers below the ground.
Despite the time, many users on social networks reported how the earthquake struck from different parts of central Colombia. One of the highlights is a video shot on Meta, where you can see the power of telluric motion shaking utility poles and some intermittent flashes of light in the sky.
This is not the first time such a phenomenon has occurred, in fact, blue-toned lights have been seen in Mexico, In the 7.1 magnitude earthquake that occurred in 2021, as well as the devastating earthquakes in Turkey and Syria in February of this year.
And although it has become a shocking event, it is actually an event that has been recorded since 1660. We’re telling you.

Experts often explain that earthquake lights, or triboluminescence, are caused by the release of electrical charges from rocks in the earth’s crust that produce this type of flash due to telluric motion causing their crystals to collide.
Often people who observe this phenomenon believe that it is the explosion of power cables due to strong movements or the light produced by electrical transformers.
However, according to Esteban Hernández Quintero, expert and former coordinator of the Geophysical Services of the UNAM Geophysics Institute, it is most likely the university’s paper in question. Collision of Grabo and basalt crystals.

The friction produced by the telluric motions causes the crystals of these minerals to collide with each other, creating an electrical discharge that is perceptible to the human eye. They are usually blue in color, but also It can be shades of red, white, yellow or green.
There are nations that are constantly confronted with narrative movements because of their geographical location. This is the case in Japan, Mexico and Turkey. in the second, one of the worst tragedies of the year occurred due to severe earthquakes.
While there are those who believe that the lights are made up of simple power outages caused by tremors, many see the visible lights in the sky as light. a sign of an approaching strong earthquake.
After the powerful earthquakes that hit Mexico in 2021, EL TIEMPO made a video explaining what causes this strange geological phenomenon that lights up the sky during earthquakes.
