Did You Hear ‘Frightening’ Loud Booms Tuesday Night?

An Altadena resident shared that she heard loud “frightening” boom sounds consistently throughout Tuesday night but the Altadena Sheriff’s Station has no report of anything happening. Did you hear or see anything?

Was your Tuesday night disturbed by the sounds of loud booms? It was for one Altadena resident, who told Patch via email that she heard these mystery sounds all night:

I live in NW Altadena near Lincoln & Loma Alta Dr & on last evening, Tuesday - Dec 4, 2012, I kept hearing 'loud boom' sounds every 10-15 minutes. These sounds continued all night - very frightening - I called the Sheriff's Dept to report it - I never found out what this noise was. Did anyone else hear this and do you know what it was? I know that street lights are being put up on the corner of Altadena Dr & Lincoln.

The watch commander for the Altadena Sheriff’s Station told Patch Wednesday that nothing else was reported about any loud “boom” sounds and there was no explanation for them.

The most notable thing that happened Tuesday night, according to the watch commander’s report of the Altadena crime log, was a call to report a beauty salon fire in town but when fire officials showed up there was no fire to be seen.

Did you hear any loud boom sounds Tuesday or see anything causing a loud sound? Tell us in the comments.

Could it be my neighbor? When ever he drives his beat up car, my windows rattle from the bass. But he always plays rap music or Latin music. Well, that can't be it. sorry. I have some ear plugs if you need some. What a lovely neighborhood I live in.

Didn't we have this same story a few months ago ? And doesn't this happen every now and then for years? The inability to pinpoint the sound would suggest around the mountains and/or underground. But then if you ever listened to the coast to coast show on KFI, (and actually believed the guests) then it might be: 1) The original humans in the center of the earth. 2) The polar shift happening, or worse magnetic shift, which actually does happen every 100,00 years or so. 3) beings from outer space eliminating our nuclear weapons 4) bigfoot 5) the face on Mars burping 6) a parallel universe trying to communicate with us 7) The iceburgs breaking from global warming 8) The complete collapse of our universe into the singlerity 9) pre-quakes from a continental plate we never knew about, and we are sinking 10) It doesn't matter!!! This is 2012 you know, and we only have 15 more days to live!!!!!!!!!!

I've heard things too. There were alot of similar reports back during the summer months too. Here's a previous story http://altadena.patch.com/articles/reports-of-loud-booms-in-eaton-canyon

How interesting! What's even more interesting is that the Sheriff's Dept only received one phone call - I personally called at least 3x - spoke with Rachel/Raquel, the Dispatcher. It's hard to beleive that "no one" has an explanation on what this noise is; where it's coming from or what's causing it. This was the first time I've heard it - very frightening! Shortly thereafter the smell of natural gas was in the air - I called the Sheriff's Dept again - and was told to call the Gas Company. I wonder how many times the residents that lived in San Bruno had called their local law enforcement agency? hmmmmmm. Leslie, I'll have to side with your assumption JPL/NASA.

I also heard what I thought sounded like siren warnings -- not like those from the Police or Fire Departments -- but closer to old fashion air raid warning systems which were blasting with frequency Tuesday night. It's disturbing that no one can identify these noises. It does not bode well...
Brent Morgan December 06, 2012 at 07:16 PM
This actually happened about 70 years ago as well... it turned out to be the top secret Caltech rocket project my grandfather worked on in Eaton Canyon. It definitely wouldn't surprise me if some new classified project is going on at JPL or deep in the San Gabriel mountains.
Nico December 06, 2012 at 07:25 PM
Well, did you call the gas company?
Robby December 06, 2012 at 08:07 PM
I live closer to Casitas, and I hear sounds from JPL all the time. There are beeping sounds of trucks backing up, turbines whirring, bangs and crashes like drums are being tossed around, regular car horns honking, the occasional siren-like sound, etc. And sometimes booming sounds. I would have been surprised if people told me they could hear them much further east than where I live, but perhaps they are carrying up the side of the canyon really well? Maybe there are certain atmospheric conditions that carry sound better than at other times, or perhaps they are extra busy on some nights compared to others. I'm pretty sure any sounds coming from JPL would NOT be heard in the Eaton Canyon area, however. Just my theory! Put me in the "I'd guess it's JPL" camp!
Leslie Aitken December 06, 2012 at 09:35 PM
Brent -- that top secret project you are referring to was the Manhatten Project -- I worked for a trust a couple of years ago of a woman who worked there too. Among her belongings were letters from the war department thanking her for her participation in their top secret project. They were dated the day after the bombs were dropped in Japan (the Manhatten Project) and started "By know you have probably figured out what the end result of the project that you have been working on was." The government had top secret facilities in Eaton Canyon. I again say JPL.
Isabella Baumfree December 06, 2012 at 09:51 PM
Enlightening information. The apartment cottages on the corner of Lincoln & Altadena Dr. were housing facilities for army personnel during that time....

barracks for army personnel - the ones on the SE corner of Lincoln/Altadena Dr
Brent Morgan December 06, 2012 at 11:28 PM
Such incredible history in this area, I love it! While some elements of the Manhattan Project may have been worked on in Eaton Canyon, primarily the operation was focused on developing, testing, and building the world's first mass produced rocket powered missiles. The operation was moved to the canyon after an initial test at Caltech almost blew a hole in San Marino. Caltech then formed two separate rocket divisions, JPL and the top secret Eaton rocket missile project for weaponized use. The majority of all missiles used in WWII came from Eaton Canyon, it operated 24/7 and produced more than a million missiles, which helped us and our allies win the war. The Manhattan Project definitely put the nail in the coffin though.
Laura Monteros December 06, 2012 at 11:55 PM
I live near there but the elevation at my house is a tad higher. Did not hear anything. It's very hard to tell where sound is coming from with so many mountains and gullies in this area.
not Carl Peterson lll December 07, 2012 at 12:34 AM
So, their is still one old guy, somewhere in a secret tunnel that doesn't know WWII is over? Apparently he is still testing bombs.

@ Leslie & Brent - When my family moved to Altadena in 1971 there was a Military Academy - Mt. Lowe Military Academy- located on the corner of Palm & Lincoln - The main entrance was on Palm, where the two huge black gates are located. It's space covered from Palm to Dabney, Lincoln to Loma Alta. The area where the Altadena Garden; Tennis Courts; Equestrian Center are. As a matter of fact, the lone building that sits north of the park parking lot is a remnant of Mt. Lowe Military Academy. One of Ike Turner's (Ike & Tina Turner) son went there. A lot of interesting history in Altadena. This information explains why there was a Military Academy in Altadena - we sure need another one here.

Could it have been the coyote vs. mountain lion Tuesday night bowling league? Since moving out here to Fontana, I just hear trains all night... I miss Altadena...

The Army, Navy, Air Force, Marines or the CIA blew up something big. Then again let s not underestimate local private companies or even private idividuals with enough know how and gumpshun to make big boom booms. I remember as a kid one day I took a whole roll of caps ( for a toy gun) and banged it with a 15 pound rock, and some in the niehborhood thought I set off a cherry bomb. Almost any explosive in a closed area will make a big boom boom. Or could an underground fault line break or slide a bit,cause a big boom boom, but not cause an earth quake?
Sarah Gates December 08, 2012 at 12:30 AM
I heard a boom not quite an hour ago. I live on Mendocino and Catherine. At first I thought it was a small earthquake but now maybe a sonic boom?!? Did anyone else hear that this afternoon? The dogs in my area started barking right before it hit, so they heard it before I did. Love our neighborhood and the great history but these booms are mystery. Sarah Gates
not Carl Peterson lll December 08, 2012 at 02:04 AM
OK, SO NOW THIS IS WEIRD! My dog started at the same time as well as other dogs in the area. But I need much more evidence. Dogs can, and frequently do bark without me hearing what it was. But it is worth thinking about the coincidence that Sarah heard dogs barking at the same time as mine and others about five blocks away.....all right before the boom.... "Their is a fourth dimension"..... " Their is a sign post up ahead.....next stop...the twilight zone".. ne,na,na,na...ne, na,na,na

I'm hearing loud booms also, and I live in Louisiana. They are very frightening indeed.
Fred December 10, 2012 at 10:52 AM
Ground tremors go faster than sound Animals feel small tremors better than humans That is why they bark before you hear the booms: dogs react to the fast small tremors and not to the booms that come slightly later
William Korn December 10, 2012 at 03:54 PM
People who are interested in pursuing this might want to check with the earthquake folks over at Cal Tech - not because the booms are real earthquakes - they might be part of a seismic study. In such studies, small explosives are set off, or a large, very heavy weight is dropped on the ground, and an array of seismometers picks up the resulting vibrations. A lot can be learned about the local geology that way. Such studies are done from time to time by geologists connected with research outfits or with oil companies looking for new sources of oil.
William Korn December 10, 2012 at 06:53 PM
Back when the Concorde was still flying, people along the New Jersey coastline were hearing loud booms apparently out of nowhere. After much investigation, it came to be accepted that what they were hearing were sonic booms from the Concorde as it approached JFK Airport in New York City. Under particular atmospheric conditions, the sound was carrying over 100 miles. Could it be that you are hearing sonic booms from military jets flying over the Gulf of Mexico? It depends on where in Louisiana you live, I suppose.
Kristin Zeringue December 10, 2012 at 08:13 PM
Well thank you for your opinion Mr. Korn, I sure hope aircraft is the reason for these loud, mysterious disturbances. I heard some 'end of the world' nonsense and honestly, it had me spooked.. I just don't like not knowing where these really noisy sounds are coming from because they do not sound good AT ALL.
not Carl Peterson lll December 13, 2012 at 07:08 AM
Hey Kristen...If you were referring to my post about "end of the world" it was all in fun. I was really poking at the overnight show that always has a strange idea. We are not at the end of anything .....yet.....well....oh uh....nevermind.
John Jacob Jingleheimer Schmidt January 02, 2013 at 04:01 PM
There are loud booms going off in lower Arkansas and have been for a few weeks! I am beginning to wonder if this is some new testing of a new aircraft, like the SR-71 Blackbird. It apparently is not happening in one place but all across the U.S. Any new theories?
William Korn January 02, 2013 at 06:10 PM
It may well be, Mr. Schmidt (see my comments above). Alternatively, it could be the Mayans banging on the gates of the Underworld from the other side. They want the heads of those fools who misread their calendar.

Lord have mercy! For all you folks that are tempted by conspiracy theories, here's an exercise for you. If you can bear to get through the entire article referenced above, can you explain why it's a great steaming pile of bullsomething in in less than 25 words? I can do it in two.
