I was Wow-ed to discover one way that the moon can be "turned to blood" (Joel 2:31, Acts 2:20, Revelation 6:12). It is the result of fire+smoke.
California’s Carr Fire may have unleashed the most intense fire tornado ever observed in the U.S.
I also just discovered there are such things are "
fire tornados."
You're right that fires and smoke can cause the moon to appear red, but it is more commonly caused by a total lunar ecclipse.
There are several prophecies in the bible that foretell of events in the sky that appear to be cataclysmic, but actually are not. They are merely signs of times.
For instance, the sun turning dark does not mean that the sun is going to be "switched off", but only describes a solar ecclipse. The moon not giving its light occurs with every new moon.
The only question is, since these events are only visible from certain areas of the world when they occur, where is it they would be visible from? The only place on earth of any "biblical" significance is Jerusalem. So if you like to watch for these things, look for a solar ecclipse followed by a new moon, both visible from Jerusalem.
Gen 1:14 - And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:
Joe 2:31 - The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD come.
Mar 13:24 - But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light,
