Another very loud boom was heard in Concord on Wednesday night.
Who heard it, and where in Concord do you live?
Live near Markham Nature Park! Scared the crap OUTTA ME!
VERY loud in Holbrook Heights in N. Concord!
we heard it and we live near concord high, what is it with all these big booms lately?
On Claudia at N. 6th, sounded like it was on Ida. (Concord) shook the windows.
Heard it here in NC we are over by N 6th… what the hell is it?
On Laguna near the Bart station. Heard and felt it!
Loud!!! Off Clayton Rd.
i heard it. i live by the drive-ins.
It was a mortar type firework. Nothing to see here, move along.
I heard a boom about 45 minutes ago. I live in North Concord. It sounded like it was some distance away. (Not as loud or close as the last one I heard several weeks ago). Hard to judge, but it sounded like it was coming from the direction of downtown Concord.
I heard it 8:39 PM – corner of Claycord and Olive
Claudia and Olivera. Very loud. Shook whole house and the trees in my backyard.
We’re off Court Lane (treat and cowell). We’re bar b q ing and heard it louder than usual at 8:37. Probably another m80… Someone does this all the time. Getting used to it and not so scared anymore.
Salvio, by the library. Enough already.
Heard it in Martinez, but then we are kinda used to it. lol.
Holbrook Heights NConcord….yes sounded similiar or like a m1000
Garden ave and High School. Shook the windows.
I live on Granada and I heard it. I was standing in my back yard, it sounded like It came from the willow pass park area
And it will be brushed off as gunfire. . What’s the real cause behind these booms? We may never know … Until its too late
Didn’t hear it this time! by CVHS
I heard it. It was loud and with a long echo.
I’m a block from CVHS, heard it loud and clear.
Heard it here and it sounded like it was next door.
Remember the really big one a couple of months ago that those of us in Holbrook zeroed in on as having come from around Holbrook Pool area? Well this one was twice as loud. I think I heard a wall crack behind me!
Oh, and yes JWright is correct, this one did have a long echo.
Anyone know what it was? I didn’t hear it here in Martinez but I’ve read this wasn’t the first loud boom and I have family in Concord.
Don’t hear a thing. Near Clayton Rd and El Camino.
Live on Citrus Ave in Walnut Creek – heard it loud and clear !
Should have said “Didn’t” hear a thing. LOL
Yup Port Chicago and Olivera– Thinking Willow Pass Park — same as usual — not happy about it but getting used to them (sadly)
Near Concord Boulevard and Bailey Road. Sounded dull like dynamite and seemed to be southwest of here (maybe coming from over toward Clayton Road and Denkinger intersection….one of those neighborhoods).
Heard it in N. Concord/Holbrook Heights neighborhood. Scared the the you-know-what out of my dogs.
This is getting old.
Heard it on Bailey.
I’m 99% sure it’s some kids playing with home made stuff. Making a loud boom isn’t hard to do.
It’s most likely acetylene balloons. They make a lot of noise and very little damage. If you’ve worked in a shop you should know about them.
I certainly heard something after having chili for dinner.
Heard it here by cvhs, I don’t even get fazed by them anymore!
Heard it over off Pine Hollow Rd.
Missed it, darn quail havin’ a loud party out in the garden.
BoomBoom goes the neighborhood!
We heard it off of west st even the squirrels got scared !Im thinking dooms day preppers doing a practice drill!
I don’t know about a boom, but does anyone know about the Haz Mat cleaning on Pleasant Hill? I was on Oak Blvd and one of the cross streets had 2 haz mat spil trucks, fully equiped people on suits and masks, cops…the whole 9 yards…cleaning something…it looked like it was a house?!?! scary!
Loud and clear here in Canterbury. This one actually seemed significantly louder than the most recent ones.
We heard it on top of Ridge Drive
State streets closer to Circle K heard it
Heard it on Clayton Rd & Treat. Really tired of this.
Heard it over here off West and Chestnut!!!
Heard it off Denkinger and Clayton Rds. Thot it was odd.
Heard it from the Dana plaza parking lot on concord and landana
Get over it
Heard it loud and clear on Richard Ave. These fireworks or whatever are getting pretty old!!!
Rancho Diablo, Pleasant Hill.
Maybe it’s like this incident across the country http://www.hamptoncountyguardian.com/news/mysterious-loud-boom-explained
I have never heard these booms, but I have heard from people that they are detinating ammunition, etc, in the old naval yard.
Just me switching to warp drive.
I was visiting my friends who live on Fitzpatrick and it was veeery loud. It was in the next door backyard. Very scary…some measurements should be taken.
I am guessing this is just a warm-up for July 4th.
sorry ate at OSF again. Up all night too
I heard it. Swore that it was right outside my house and I live between grant street and the hospital. CRAZINESS! and i don’t like it. :/
Seems like every other night there is some explosion sound. Just another day in paradise..
there were news reports of loud booms in other states just about a month or two ago, and people in those states got no explaination. concord is right next to a suposedly closed military base. I’m sure there is nothing going on over there….wink wink
for those playing with acetylene be advised that once it goes above 15psi it can self destruct.
Don’t loose your thumbs, or die.
Another liberal watched Fox News on a dare. Head exploded. Happens every time.
@Monica #52 — that is very interesting – I am not liking the thought of someone shooting a high powered rifle anywhere in the area .. If that is what it takes to set of a charge..
Is it really that difficult to narrow down where this is happening? This is a large explosion. You would know if it happened next door.
On another note, right after the explosion, the leafhoppers invaded my garage. Could it be related? Was it a leafhopper bomb?
We heard it in Ho;brook area. My husband saw the flash. Somewhere off of Esperanza or Willow Pass. Car alarms were blaring!
are no govt. agencies checking this out or saying anything?
In FL people are hearing what sounds like a train running under the ground with shaking an all. interesting that this sort of thing is happening on each coast.
So what was the mayors big jaw dropping news looked for it on claycord but to no avail
In Pine Hollow neighborhood…didn’t hear this one.
Has anyone who personally heard it called the police before jumping on Claycord?
Maybe a bunch of matching reports would get some interest from the law…
Considering there was a flash, I believe that some morons are setting off some pretty high explosives to get their rocks off..I love the Holbrook neighborhood but there are a lot of thugs in the area. So sad.
Yep, heard it LOUD and clear. I’m in Bishop Estates off Concord Blvd., and was just getting back from a walk with the dog and BOOM! Dog heard it too. Sure wish there were some answers to what the heck is going on!
Heard it and felt it by Hillcrest park
Loud but distant. Live just West of Cowell Park. Our dog, who hates fireworks, was lounging in the backyard – he noticed but wasn’t scared.
Off kirker pass…..totally heard it.
I live near Willow Pass and Parkside and it was loud her almost sounded like more then one. Maybe just the echo. I happened to be looking out the window when it happened and it sounded like it came from Mt. Diablo High School area or possibly further that direction towards the Drive Inn.
“Underneath most major cities, especially in the USA in fact, there exist subterranean counterpart ‘cities’ controlled by the Masonic/hybrid/alien ‘elite’. Often surface/subsurface terminals exist beneath Masonic Lodges, police stations, airports and federal buildings of major cities … and even not so ‘major’ cities. The population ratio is probably close to 10% of the population (the hybrid military-industrial fraternity ‘elite’ living below ground as opposed to the 90% living above). This does not include the full-blood reptilian species who live in even deeper recesses of the Earth.” from http://www.whale.to/b/underground_h.html
i propse to you good ppl, their is a war in our backyard, we may want to develop the old navy base but our repitlian overloards may not give up the land so easily
why are the booms only coming from north concord?
why isnt the city at all care about these supposedly alleged ‘fireworks’ when im sure their are many complaints to the PD and city itself?
too many unanswered questions, tinfoiler can you inlighten us?
Here’s the weird thing-I am in Pleasant Hill and didn’t HEAR anything…but SAW a crazy large blimp-looking light filled thing with one blue light on the side. It looked either HUGE or really close. It was big and bright enough to catch the corner of my eye while riding my bike really fast in the opposite direction. It was so fascinating I chased it on my bike for a while, through Strandwood Elementary, up a big hill and out to the street on the other side. As I got closer it got smaller and starting moving off into the distance and the light on the side turned red. Then it was gone.
I called my friend who came to this website to see if anyone else saw..
Wonder what could do that?..
Iwas driving in willow pass caming from baypoint.and.with my windows car down no music radio off and . heard a.bigger boom.but same time isaw lighting in the next to.the railroad inside the naval weapons maybe some other persons .see.sameting.like me.and my wife.but if there’s someone who’s work inside the naval maybe cab explain more about it.for everyone.
Does light turn red as it moves away from you? Can something moving really fast make a loud noise?
just heard one behind our house in the park…Concord high…kids laughing so just called 911…waiting to see if I hear cops coming.
my son called the other day because he found needles at the tree line next to the fence.
It’s a mixed issue…if we ask that the trees be thinned out so the teenagers can’t hide and do crap in them then we will also hear more Concord Blvd street noise. I’m a night owl and I sleep with my window open but I have the TV on and sometimes a fan….so even tho I’m that close I miss some of the booms. Plus I swear the noise travels around the house from the high school side to my side….
My buddy Antler and I live pretty close to each other and we hear different things….very strange…..GoGo says bottle rockets sometimes and I swear sound like gun fire.
well, I hear a serious voice and no more laughing…did not hear a cop car tho….
Why are Concord residents always imagining strange sounds?? We in Pleasant Hill never hear loud booms.
It’s the IRA testing out their new bombs on the Naval Weapons Station property. Getting ready to ship them back to Belfast.
Beacon at #64 ~ ~ ~ OH, NOOOOOOOOOOO. The leafhoppers are back already?????? Thanks so much for jogging my memory that I need to get the kitchen window screen repaired.
Roskelly or Athena Drive is my guess. Near the Esperanza side.
My husband and I saw the spark and smoke cloud
i was hoping it was pleasant hill recycling blown up they are such rip offs
As a kid I would have done this just to see how fast it would be posted on Claycord and how many people had heard it. Just adds to the fun.
Finally the Government Drones have been armed!!! I believe they were shooting at several 32oz sweet drinks spotted outside the 7-11 on Olivera Road.
I live near KMART, and so far I haven’e heard any of this bog booms.
I’m across from farm beau rd and I heard it this is the 2nd one with in weeks. Wonder what is going on.
I saw the resulting smoke cloud from the device. It was an aerial mortar (firework) from the north end of Ida, Meadowbrook, or Claudia, by 6th street.
I live in Northwood Circle and heard it. Living by the refinery is oh so fun.
Heard it at exactly 8:40 pm, I live on Acacia which is off P. Chicago in N. Concord and it scared the living crap out of my dog yet again. Didn’t see any flash or anything just heard the big boom.
BIG BOOM……Concord Blvd & Bishop
Spoke to someone in the city office, they were going to do some investigating,I could not remember all the dates that explosions have taken place, but they were going to check on Claycord, and speak with Mike Wright, who is working on the Reuse of CNWS. I hear people call in, over the scanner, so I know they are being reported, just not located, which seems strange to me, since they are loud and seem to vibrate. Anyway maybe we will get some answers or they will find the source of this energy.
LOL! yeah, they’re detonating old ammo at the navel weapons station! Yer killin me!
Saw the one before this. From experience using them I’m satisfied its commercial grade fireworks.
Think it is a few kids with M-1000`s
And they just love seeing that they continue to get posts put in here about them.
They think it`s cool to scare the old timers.
And they laugh at how many times it`s mentioned in here
Concord Blvd. near Concord High School. The dog was in the back yard and just as we heard the boom she started barking and wanted in the house.
It`s going to be tough to catch them in the act.
Because it is thrown from a moving car most of the time.
So by the time the blast goes off.
The car is blocks away.
All that can be seen is the bright light and smoke.
Unless someone sees what car it is thrown from.
There is no way to catch them.
Did not hear anything…Live in N Concord
Exactly. It is just kids with fireworks. I don’t know why everyone get all strung up about it.
Some of you laugh this off as kid stuff, well I do not find it funny, and if you are parents of these adorable wannabee hoodlums you are just as responsible. HAHA thrown from car…or kids having good time scarring old timers….wait until someone is hurt or worse, or a house is lost from fire. You adults out there need to be responsible……if you see kids doing this turn them in, Fireworks, m1,000s dynamite is illegal……DO YOU REALLY THINK THIS IS A JOKE HATE TO SEE FOURTH OF JULY. And if you are on my street and I see you I will call the police. We just installed security cameras so hopefully you will be caught in the act. LOL
Yea fireworks are only illegal in Cali , Cali sucks and you all should get a life and leave it to the authorities
We heard it and felt it. Live Hwy.242/Grant St./Solano Way
I live near Concord Blvd and Bailey. I not only heard it, but I felt it. If this happened in Holbrook Heights, we’re not talking about kids and fireworks. Someone set off a bomb.
Smokey…..Thank You …A voice of intelligence…….
“Here’s the weird thing-I am in Pleasant Hill and didn’t HEAR anything…but SAW a crazy large blimp-looking light filled thing with one blue light on the side.”
I’m not certain if this is what you saw, but I work in Pleasant Hill, and my co-worker pointed out a blimp in the sky near our office. It was white with a light blue stripe on the side. It also had some writing, but I couldn’t quite make all of it out. I believe one of the words was “Vistas”. I thought it might be adversing a housing track or new apartments in the area. I wonder if this was the same thing you saw last night.
I live off north sixth in concord I hurd the blast ad it set off car alarms going off and dogs hella barking.hurd it over my music secend time twice now.someones haven fun c how long that lasts before u get caught!!!!!!!
For those people who think Concord Naval Weapons base is “closed”, only parts of it are closed other parts are still active.
In 2008 control of the site was changed. The Inland Area became a Detachment of the Naval Weapons Station Seal Beach, pending ultimate closure. The Tidal Area was transferred to the U.S. Army Surface Deployment and Distribution Command (SDDC) and is now known as Military Ocean Terminal Concord (MOTCO). This facility was also used by the Diablo Squadron and Training Ship Concord of the United States Naval Sea Cadet Corps
Somebody set us up the bomb.
Between Landana and Granada.
What you say?
On Ida dr., near off of North sixth and Port Chicago Highway this isn’t the first time that same boom has been heard in north concord
Ithink it was nuclear
Heard it for the last 3 nights about 8:30 or 9:00 P.M. Live near the airport. It scares my pets and it scares me! Sure am tired of it. Why can’t this mystery be solved?
