Scientists explain skylights just minutes before the Morocco earthquake

The “The days of the” earthquake, such as those seen in the videos captured at the moment when the earth began to tremble in Morocco, date back centuries to ancient Greece.

These colorful flares, which were recently filmed after the 6.8 magnitude earthquake last Friday in Morocco, have long left scientists speechless and still no consensus on what causes them.

“however, remains undoubtedly real,” says John Pig, retired geophysicist who worked in the US Geological Service. He is coauthor of several scientific works on earthquake lights, or ECL.

See ECL depends on darkness and other favourable factors,” he explained.

He said the latest video from Morocco on the Internet was similar to the lights of the quake caught on security cameras during a 2007 earthquake in Pisco, Peru.

Juan Antonio Lira Cacho, professor of physics at Universidad Nacional Mayor de San Marcos in Peru, and Peru's Catholic Catholic University, which has studied the phenomenon, says that the widespread use of security cameras has made it easier to study earthquake lights.

“2zet years ago, it was impossible,” he said. If you could see, no one would believe what you saw. ”

Earthquake lights take different forms
Earthquake lights may take different forms. Sometimes they may look similar to normal lightning, or they may be like a shining generation in the atmosphere similar to the polar aura.

Researchers have found that about 80% of such phenomena, studied, have occurred in earthquakes with magnitudes greater than 5.0.

In most cases, the phenomenon was observed little money or during seismic events and was evident up to 600 miles [600 km] from the quake's epidera.

Possible Causes of Earthquake Lights

Friedemann Freund, associate of the Pig and associate professor at the University of San Jose, has come up with a theory about earthquake lights.

He explains that when certain defects or dirt on rock crystals are exposed to mechanical stress, such as during the rise of tettonic stresses before or during a large earthquake, they quickly break and produce electricity.
The rock is a kind of insulator that, when stressed mechanically, becomes semi-discreet, he said.
