MYSTERY BOOM HEARD ACROSS SAN DIEGO, USGS SAYS IT WASN'T AN EARTHQUAKE

Underground bunkers? Underground railroad?

the collective attempted to create intelligence failed again?

No .

Pics or it didn't happen

underground bases again?

a such boom with no seismographic records can hence only have happened in the air ... tic tacs blowing a PRK drone with some little kim tactical nuke bomb?

Loud geese!

Underground military bases

I think it's the large crane's "Cranium" that are all downtown in cities. I've seen them and they even move at night.The owners of this site tell me. I am the first human comp hybrid

I live in Ohio and something like this happened about five years ago in Northeast Ohio. Early on a Saturday morning and there was a long and loud boom. I lasted for about 10-20 seconds. The whole house shook. The dog actually had woke me up about a minute before as she was whining and nervous. That was pretty unusual, but I think she sensed something before it happened.

It was sort of kind of reported on briefly and attributed to some weather phenomena. It was spring (I think April) and there was no weather in the area. It was sunny and clear skies.

I spoke to several neighbors. I brought it up and people felt ok to talk about it, but no one wanted to be the weirdo who is afraid of loud noises or conspiracy theorist. Strangest thing I’ve ever heard.

Realize all this is written in the book.

Better get right

Just the government.

F-18D Superhornets going supersonic over the ocean. nothing to see here .

We used to hear these booms on the beach there back in the early 90s. CalTech and the USGS repeatedly stated that the cause was not earthquakes. The police and Sheriffs said they had no explanation.

We all suspected that it was the Military testing the new supersonic bombers out there near San Clemente Island, with sonic booms as the actually cause.

Another possibility would be space debris entering the Earth's atmosphere near there. If that can't be proven, then most likely it's a foreign or domestic military's operation of some sort.

Are there any Chinese or Russian ships or planes in the area???

Sonic boom was my first thought too.

Probably from Miramar..

Special forces are clearing the DUMBs and killing off the demonic entities and holdover derp staters.

I live in San Diego. I have been telling my roommate that I have been hearing these booms the last several months. He thought I was crazy until I pointed them out to him. Now he hears them constantly and is seriously wondering himself.

They happen when there are no planes around, nothing in the sky and nothing huge happening on the ground. I have felt the ground below my feet sink a couple times. Really bizarre.

I have no clue what is hapoening but I can tell you it's very real.

Occum's Razor

I've heard 2 in Alabama a year ago and they made my dogs bark also.

is someone testing new weather modification experiments?

Meteor? Sonic Bomb?

sonic boom. happened yesterday in vegas, too. getting prepped to penetrate iranian airspace.

Another dumb collapsed

BREAKING! FALSE ALARM!
Michael Moore just apologized on twitter stating he didn’t mean to cause such a ruckus. He unfortunately had gas after an all-you-can-eat binge at the Sizzler.

I just heard on ATL news they are doing controlled underground explosions in downtown til March.

I heard it. Navy fighters practicing off the coast near San Clemente island. Sometimes they exceed the sound barrier in mock dogfights and create a "sonic boom".

Back in the sixties we heard it every day.
