Really intense across from Assateague at my house. Glasses rattling, windows shaking and the cat freaked out. Loud rumble followed by 5-10 seconds of shaking. I though it was a rocket launch at Wallops so ran to the front door to look but didn't see anything.
The first thing I thought of was a boom, either from a rocket or a jet. But it was a rolling rumble with peaks and valleys and it lasted so long. Even my window blinds were swaying. Never felt anything like that around here.

OCEAN CITY, Md. and SUSSEX COUNTY, Del.- Naval Air Station Patuxent confirms that 2 flights conducted off the Atlantic Coast caused the sonic boom heard over MD's Eastern Shore.
Earlier on Thursday, emergency management officials have received numerous reports of tremors in Ocean City and coastal Sussex County, Del., but both a federal and a Maryland agency did not show an earthquake having occurred. There have been no reports of damage.
SU Professor of Geology Dr. Tom Cawthern said to be able to identify an earthquake, the seismic activity needs to show up in various locations.
"This is one bit of information. This is one seismograph from one discreet location. If we pull together all of the seismographs from say the South Central part of the US or even in the North East, we should also see those data in those seismograms as well," said Cawthern.
The reports of the tremors, also described as "shaking," starting coming to Ocean City officials, the Maryland Emergency Management Agency, and the Sussex County Emergency Operations Center and in social media postings about noon on Thursday.
Ocean City officials posted on the town's Facebook page that residents also reported hearing a loud boom. Similar reports were posted by viewers on WBOC's Facebook page.
"Any time you get a sonic boom say, you are compressing the air and that air is, if you are directly under the flight pass of that jet that's gone super sonic, then you would expect that compressed air to have some sort of surface that you're on," said Cawthern.
Back in the mid 90s there was a "rogue wave" - 17 foot high - that hit Daytona Beach on a flat day! You can drive on the beach, and sunbathe next to your parked car. People were swept underneath their cars by the surge. No storm, no earthquake, although it was credited to shifting sands. I call BS!!! It was obviously the armed forces testing something or another. Keepin' 'Merica safe! God Bless Freedom! And the U.S. Armed Forces. Charlie don't surf. We are soooo lucky.
I work right by Assateague. We get sonic booms quite often...it rattles the windows at the shop every time. This one was different...it started out slow and got really strong and fizzled out. It wasn't quick, but extended for maybe 10 seconds. It was quite strange sensation compared to other ones we normally feel. One soon followed after that one. I knew it wasn't an earthquake because the clothes we had hanging would sway, which happened when we had that quake near dc a year or 2 ago.
