Same here...and I lived in Colton's Point back when they were testing 16" gun charges back in the 80s.It was unlike anything I have ever heard or felt from Dahlgren testing.
I know the people on Facebook who asked lived on the western side of St. Mary'sIt’s amazing how the sound,etc traveled IMO because my sons live in the ranch estates and didn’t feel hear a thing.
So wait and see if it repeats per the schedule. The atmospheric conditions were kind of odd with the heavy fog this AM. The event happened after the fog burned off though. I was outside can't remember the exact time.
Yep felt it pretty strong in Wildewood.Just happened again.
