Earthquake lights can take several different forms, according to a chapter on the phenomenon coauthored by Derr and published in the 2019 edition of the Encyclopedia of Solid Earth Geophysics.
Sometimes, the lights may appear similar to ordinary lightning, or they may be like a luminous band in the atmosphere akin to polar aurora. Other times they resemble glowing spheres floating midair. They may also look like small flames flickering or creeping along or near the ground or larger flames emerging from the ground.

I did not see a video in the article. Here is a video of the lights on msn. I can’t figure out how to get an English page on there. Sorry.
Hola from s Puerto Rico, having survived 500+ earthquakes I’ve never seen these lights and have never seen security camera footage of these lights. I have seen transformers explode in earthquakes, those make pretty lights.
The term comes from the Greek τρίβειν (“to rub”;
Uh, brb, gotta go try…something.
