LA quake rainbow appeared, and then there was a quake

On May 15 I wrote that people had spotted what has come to be known as a "quake rainbow" over Los Angeles. Weatherspace.com was reporting that a "quake rainbow" hovered for hours over the city, which some say portends an upcoming earthquake. Similar rainbows had been spotted over China before their quake and also Peru prior to theirs. An alleged quake rainbow is a rainbow that does not arc in bands of color, but instead is a colorful patch that hovers. Of course, Discover Magazine debunked the phenomenon (if it is one in the first place) here. But Physics Forums maintained a scientific inquiry into the quake cloud issue, here, and excited sky watchers of all stripes exclaimed over the coincidence: here. Maybe quake rainbows are a thing, and maybe they are not.

But then a day or two later there was a 5.1 quake in LA. Coincidence? Could be, LA is very seismically active. Not a coincidence? You decide.
