|Extremely loud sound accompanied by vibrations (5-7 min duration) occurred twice in 10-day period in Yakima County, WA in early AM.
Approximately 2am in the morning, I and others I know awoke to a very large mechanical sound with vibrations coming from the sky. The vibrations were so powerful, the house was shaking similar to minor earthquake. Both myself, my wife, and others that I have spoken to also witnessed (heard) the event. The event lasted 5-7 minutes. After going outside to see what the sound was, there was nothing visible creating the sound and vibrations. I have spoken to several others that witnessed (heard) the event at several locations in the Upper and Lower Yakima Valley. I am an aircraft pilot and have flown and been in many types of planes, and this sound was not from any piston, turbine or jet engine. People described the sound as if standing next to the launch pad of a rocket. I have spoken to others that stated similar event occurred 10 days earlier on 11/1/2019.
In an attempt to record a future event, video cameras (on hillside overlooking valley and pointed to sky) have been set to start recording upon loud sound and will hopefully record any future event.
