What are the EQL auroras Delhi witnessed during the earthquake

The terrible aftershocks of the earthquake have hit hard all the north-west of India. But Delhi has witnessed a unique phenomenon.
Earthquake lights are a phenomenon that appear in the sky at or near areas of seismic activity or volcanic eruptions.
Earthquake light appearances appear to occur when earthquakes have a high magnitude, usually 5 or greater on the Richter scale.
During the 2003 Colima earthquake in Mexico, colored lights were seen.
More recent appearances of the phenomenon occurred in Sonoma County, California on August 24, 2014 and Wellington, New Zealand on November 14, 2016.
A possible explanation could be the local disruption of the Earth’s magnetic field and/or the ionosphere in the region of tectonic stress, resulting in the glow effects observed from ionospheric radiative recombination at lower altitudes and higher atmospheric pressure or as aurora.< br />
Some netizens shared the videos from Delhi where the sky seemed to appear a different color like orange or blue.
But there is no consensus among geophysicists as to whether there is solid evidence for earthquake lights.
Strong earthquakes rocked parts of northern India sending shockwaves through Delhi-NCR at 10:17pm on Tuesday as a magnitude 6.6 quake struck the Hindu Kush region of Afghanistan.

The aftershocks lasting about 30 seconds forced panicked people to rush out of buildings and into open areas as fears reignited of a “major earthquake” that would hit the Indian Himalayan region, as predicted by experts. There was no immediate report of any loss of life or property.
