BREAKING FIRST ON 3 UPDATE: What's causing these booms?!?!

I heard the one at 2:20 on Friday in Pender County. It shook the windows and sounded different than thunder or an explosion. It was loud,but kind of muffled.

but most likely from the marine jets that were landing and taking off at ILM yesterday. Saw them from the fair,

I had just got off work around that time Saturday morning,and was standing in the parking lot talking to a few of my co workers. We heard loud booms and looked up; we saw several jets flying around. I don't if these jets were responsible for all the trembling, but it wouldn't surprise me.

heard the booms this morning then around 630 today driving through brewsters place and i heard it again so i stopped and looked and looked out my window and saw what looked like a ufo zoom across at extreme speeds it freaked me out. I dont know what the spacecraft was but it was to fast to be a plane and looked like your typical ufo

The booms are refered to as the SENCA Guns. Pronounced Senica. (It stands for South Eastern North Carolina ) These booms are recorded as far back as Colonial times. No one has ever been able to fully explain them. The best explination is a sharp change in air temp as we have experienced the past few days brings that sonic event.

This morning (Saturday) my daughter and I heard a loud boom in Winnabow around the same time again - 10:15 am. My husband was in Leland and heard it as well.

Maybe there IS something to that Seneca Indian legend.....

This AM in Mallory Creek in Brunswick county there was a loud boom like someone hit my house and then 20 min later the house shook.

It happened again this morning (Sat. 11/6) at my house in Wilmington (about 2 miles from downtown) -- right around 10:30 AM. Have there been other reports of feeling another rumble/quake?

They are "Mistpouffers".

I live in Landfall and felt it at 2:18 pm Friday Nov 5, and again this (Saturday) morning at 10:27 am.

I live near Ashley High School and at about 10:12 this morning there was a very loud boom that shook everything! It sounded like a bomb went off! My windows rattled as well as the doors on the kitchen cabinets. I used to live across the river from Camp Lejeune and when they ran exercises we would hear and feel the artillery. This event this morning though seemed much louder and more violent than I ever recall the base being. Then about 10 minutes later it happened again, only not as loud or violent the second time. It sounded as if it were coming from the south or from the direction of the ocean near Carolina Beach. After the first event I walked outside to find my neighbor out there wondering the same thing I was! What was that? On another note both the dog and cat have been acting a little strange (nervous) since yesterday! It's a mystery!

We live in Leland - it was LOUD, we thought something had falled against the house!!!

Felt and heard it yesterday around the time the police were at first bank i live just off of pine grove. It shook the house and my windows. Then this morning about an hour ago it happened again twice. Thought maybe all three times it was an accident but no sirens. Would really like to know what the heck it was. "Seneca Booms" maybe.....

Happened again this morning, between 10 and 10:30; and it was LOUD. Shook the windows. (Leland area)

Just felt another one today, Saturday, Nov 6, a little after 10AM in Leland

It just happened again at 10:11 a.m. Saturday. Live a couple miles north of Snow's Cut Bridge. A very loud boom and a sudden shaking of windows. Could feel the shake through the floor.

We just felt the sonic booms at 10:15 or around that time, we thought it was my neighbor next door but no one was home! We felt it yesterday to at around 2:00!

At 10:12 am something shook the house again today.

WOW, just happened again, anyone feel that? Sounds more like the Senecas...it's happened here for years.

If I remember correctly, the last time this happened it turned out to be military training off our coast. Marine Corps in Jacksonville denied having any training going on last time too. About a month after the incident they said they did have jets flying off our coast and one may have come in too close delivering a sonic boom to SE NC.

Guessing maybe the same thing happened again. Obviously if training is still going on the Marine Corps can't fess up until this specific training is over.

I felt it at work. It def was not normal. The windows in my job almost burst from the shaking.

It was just the Seneca Booms, AKA: Seneca Guns. Happens nearly every year in the spring and fall as the weather starts to change. This atmospheric anomaly has been occurring in Southeastern NC for as long as I can reminder. Some say it is caused when large methane gas bubbles escaping from the ocean floor create something similar to a sonic boom. You can read more about it at the link below.

I heard a rumble like thunder close to my house in the Ash/Shallotte area. A good 3/4 times. My friend heard it at her house about 15 miles from here and said it sounded like an airplane flying to low right over her house and felt a vibration. I would like to know what is going on (and this all happened about 40 mins to an hour ago)

Those of us who have lived here all out lives call it the Seneca Guns. Look it up.

For those of you NEW to the area, there is something called Seneca Guns. For example: If a sea wall collapse's, in the ocean, it can create the feeling of an earthquake! learn or move on!!!!!

Around 2:15pm on 11/5/10 there were 2 big booms that shook our house and windows, and shortly afterwards I heard 2 jet planes flying out over the ocean. We hear and feel these booms often, and always hear a jet in less than a minute. My husband said they're pirates fighting off the coast over mermaids on Mermaid Point on the West end of Oak Island. You be the judge!

We live off of River Road in NHC. I was on my front porch. There was a loud noise and the doors and windows of our house rattled. Dogs in the area started barking. Did anyone check with Sunny point or the port?

My boyfriend and I both felt it shake my house in Pine Valley around 2:15 pm. I was worried it was an explosion, but obviously we didn't see anything. As far as the Seneca Gun theory, I've heard and read a little about them. The "Seneca Guns" are supposed to be heard off the coast, specifically near Fort Fisher and Southport. They are described as a cross between and "earthquake and a sonic boom." Although I doubt the Seneca Guns are supernatural, it is also improbable its the continental shelf breaking off, as the slope is gradual there. So in essence, I'm as dumbfounded as everyone else.

"Marine CORPS" (with the "s") - Maybe the Seneca Guns?
