Sun spots.
I expect other west coast fault activity ranging from Juneau on down. (due to recent massive sun spot activity).
Probably just a concurrent thunderstorm.
To me, being from an electric utility background, that looks like faults on the distribution system feeders reflected on the low altitude clouds. The blue-green color would be consistent with what I have often observed.
This is what I believe was observed, and I am sticking to my analysis.
Niribu crashed.
Swamp gas.
The last two earthquakes in our area produced this greenish light for some of us to see and some not to see. This has happened at night.
If it is a quake with the long rolling action versus bam, the ground will often roll like a wave. This sometimes creates static electricity, which some of us see. I saw it, my nephew saw it and one son and his son saw it. Some neighbors saw it and some in the same household didn’t.
An adult friend of our grown sons was a CHP Pilot, and he and his co pilot were up during one of the rolling quakes.
He saw the light clearly as the ground rolled along below the copter. His co pilot never saw it. They argued about who was blind or seeing things, until they found out seeing the light was selective from person to person.

strong magnetic field?
This might explain it.
HAARP emissions and chem trails interacting with each other. Who doesn’t know that? Sheesh........
If you go back and read the first-hand historical accounts of the massive New Madrid earthquake and aftershocks (1811 - 1812) you would see many multiple accounts of the exact same phenomenon.
Lightning is commonly generated during seismic events. It is the piezoelectric effect of compressing crystals.
Since it is ground generated rather than sky generated, it probably has some metallic ion content associated with the minerals found in the ground where it emanated. Copper for green, cobalt for blue, calcium for red, iron for orange, sodium for yellow, etc.
Exploding guacamole...
Not so mysterious. Probably just power line transformers blowing. Seen it many times during heavy wind/rain storms when tree limbs knock down power lines. I suspect an earthquake could cause similar damage when buildings are coming down.
Maybe now you will start listening to Frank Hoogerbeets!
Static electricity discharges.
Trump’s fault!
