What in the world would cause atmospheric light flashes and audible explosions for 80 square miles

Not sure where to report this anomaly. Atmospheric bright lights and huge explosions likely seen and heard by at least 100,000 people if not many times more. Woke up to an unbelievably bright flash of light then what sounded like the loudest longest lasting thunder I and many ever experienced. The what sounded like thunder lasting and rattling properties for what could be described as perhaps 80 square miles for at least 30 seconds non stop with a following episode shortly after.

There were no news reports, no web information other than people ringing in from at least 5 county’s in and around the Salt Lake City and Utah Valley Counties on reddit.
