I remember a small rumble thing back in...I guess it was the late 80’s, early 90’s. I lived in Glen Burnie at the time. I was married to a cop at the time. It happened in the early evening. He was walking across the floor and stopped when the earth shook. “Did you feel that?” he said and I, indeed, had.
It was scary though hardly any big deal. The next day all the local media was in a bit of a riot mood.
There was even some sort of rumble here in the swamps of Delaware little over a year ago. It was small but my toilet wobbled and the water within sloshed all about.
Though many locals felt SOMETHING making the earth kind of move, it was never proven to be any kind of earthquake thing.
I don’t live far from Dover Air Base and you should see some of the gigantic things flying into that place. Best we could figure it was some kind of sonic boom.
I was born and raised in Wilmington, and I’d drive by Dover AFB on the way to the beach many summers. It’s just amazing watching those C-5s almost hover on approach to landing. Their stall speed must be absurdly slow.
