Anyone live in a area that’s had these unexplained booms occurring? Apparently it’s been happening all over the country for some years. It’s been happening here in the baltimore area today for the last 2 hours or so. People have been panicking and calling 911. By loud booms I mean ****ing earthshaking booms that scare the shit out of you like a mac truck running into your car parked out front at 100 mph. But authorities and scientists and what not all investigate and no causes can be found. If you google unexplained booms there is all kind of information about it. It’s not thunder, nothing is registering seismic activity, military says its not them, I’m really curious what the hell it is because I’ve heard it and it just doesn’t make any sense. My local Facebook news blog has thousands of people all commenting on the loud booms and no one seems to know what they are. It really is bizarre and rather unsettling. My girl is all scared and I tell her it’s the end of the world, or spaceships are out zipping around. She doesn’t find it nearly as funny as I do
Sounds like sonic boom. If the Air Force has some radical new plane that’s doing Mach 54, I’m sure they’re not gonna raise their hand and say “Yea, that’s us. Sorry folks… but that things a lotta fun to drive. Can’t help ourselves.”
I’ve heard sonic booms before and this sounds different and much louder. It could be some kind of crazy secret aircraft, but I’m not convinced it’s coming from a plane, it is tremendously loud. It’s also not uncommon to hear ordnance going off from Aberdeen but I’m telling you this is MUCH louder and has more physical concussion. That also doesn’t explain it happening in places not anywhere near military bases and such. It literally does feel like a earthquake based on the violence coming from the ground but they happen and nothing shows up in seismic activity readings.
Never heard one but I was under the impression that those reporting the phenomenon say it sounds/feels like it’s coming from underground (but without seismic sensing/recording).
Civil engineer here who has both seen the consequences of this phenomenon AND saw it happen in person in Philadelphia (not as part of my job; just happened to see it). Do you have public sewer in the area, or do the people hearing the booms have it? If so, I’d bet anyone a bajillion bucks it’s that.
The sewer gases (methane and a ton of other acidic gases) build up in the sewer, but unlike a natural gas utility line that explodes when such things happen, sewer lines have an outlet: manholes. When the gases hit a critical mass in the sewer line, they will literally explode manholes 10s to 100s of feet in the air, which in and of itself can sound like an explosion, and then depending on how high the manhole flies, it can also cause an insanely loud noise when it hits the ground.
I never believed the reports of residents when I’d arrive onsite after these incidents. They’d always talk about how they thought it was a bomb or a low-flying jet with a sonic boom, until one of them finds a manhole missing or out of place and calls us (and we put A and B together). Then I was in Philly one day with my girlfriend, and it happened a few blocks down the street from us. The sound was INSANE. I would have sworn it was a bombing, but then I saw the manhole fly back to earth. Literally sounded like a terrorist attack. Was the loudest explosion-like noise I’ve ever heard (and as a civil eng, I’ve been on demo sights and see TNT used to break rock for excavation).
I’d check these things out if possible. The sound can carry for miles, so even if you don’t have public sewer yourself, if it’s a few neighborhoods over or within a few miles, you may hear it too.
Well, mach 54 = 18,376m/s (at sea level, not calculating for altitude pressure this time of night) or 18km/s… you could go from LA to New York in about 3:45 seconds, at mach 54. That seems to cover your reported area nicely. I declare: mystery solved!
They are down here too in S.FL. Noticed them after we moved in a couple months ago. And they are very strong too. Vibrates the house with a resonance to it, not just a single impact. We lived in northern Japan for a few years and experienced a lot of earthquakes, from the mundane to the rockn’ & rolling at 2am and falling down the stairs as we rush to get outside. But these here, they are not earthquakes.
It is from the construction of underground FEMA camps. I can’t say more because there a guy parked in front of house in an AMC Pacer. He is acting like he talking on the phone, but I know better.
I have to sign off now & put my laptop in the microwave.
