Rumbling all day TODAY (12/28/2010) in Western Washington

There is a sound bite link. Pretty much what I hear or think I hear when the rumbling noise is going on. But of course not as loud. Awesome find

This seems to be the perfect explanation.
Here is the link:

WOW.....that is incredible. I have quoted your post so that this link is at the top of this page.

ANYONE interested in this thread must go to this article and be sure to listen to the audio. THAT is so close to what it sounds like, it is just plain scary.

I have been saying all along that I felt this sound was connected to the slow tremors. This is the most recent article about it, and there is some great stuff in it!

On February 28, 2001 one of the largest earthquakes in Washington caused serious damage in Olympia and Seattle. The 6.8 magnitude quake could be felt from the Willamette Valley into British Columbia.

Scientists say the earth moved in slow motion. Where the Nisqually quake took 45 seconds, last summer’s took more than two weeks.

Dragert says these regular slow motion quakes appear to be happening every 15 months or so. They are moving the earth in a strip nearly 20 miles wide stretching from the middle of Vancouver Island in Canada down through Puget Sound extending to southern Oregon.

Evelyn Roeloffs: "It kind of behaves like a chocolate bar. Where the great earthquakes happen when the rock is like a chocolate bar that you just took out of the freezer and it can snap. And then as it goes further beneath the continent, it’s more like a chocolate bar that you left in your car on a hot sunny day. It just oozes."

As the plate slowly slips deep under the continent, scientists are quite sure this motion is not relieving stress on the Cascadia Subduction Zone. In fact, this could be adding more pressure to the very zone where a massive megathrust earthquake is considered likely.

(emphasis mine)


I want to stress here that they (scientists) are saying that the tremors may in fact be adding MORE pressure to the megathrust zone. I don't know if people realize just how big a statement that is.

I am going to try and find a valid email for the scientist in Canada mentioned in this article and ask her about the rumbling sounds. (include my sound bites)

The article states these tremors are deep, happening about 25 km deep. What if what we are hearing is even deeper, causing different seismic waves on a different freq that is not yet being monitored? What if this is the next phase to the megthrust giving way?

Just some thoughts....





Edit to add: The rumbling was again louder today....coming from the SW,like on the 28th

That sound file is nothing short of freaky. If that's what you are hearing, well if it were me, I'd be moving...sooner rather than later!

You're right, it is freaky. I'm not hitting the panic button or anything yet though. Right now, it is an anomally. I found a contact email at USGS for the scientist referenced in the above article. I have sent her an email trying to explain this as best I can while trying not to sound crazy. I will let you know if I hear anything back.

The audio on that web link was sped up 100X so that we could hear it. What you are hearing outside with your own ears has not been sped up. They can't be the same thing/phenomena but perhaps related to slow motion earthquakes nevertheless.

I would guess that there would be a whole spectrum of frequencies produced by movement of the earth the whole way in between "normal" earthquakes and slow ones. The sound coming from them would vary.

It does seem like earth is singing a different tune lately and as I said in my earlier post I can here it here in the Great Lakes region too, perhaps just less often.

Oh, I realize that it is sped up, and also pulled of the seismos...not a normal audible sound. I should have mentioned that in my post, thank you for clarifying that.

I am thinking that there might be a possibility that (if) it is of seismic origin it could be at a different frequency and speed thant the deep tremors,which would explain why it isn't currently being monitored.

Yes, this is all just speculation and I could be way off base. Puterman, who is great with seismic study and recordings thinks it may have a mechanical origin, so I could definately be wrong.

reply to post by wayno

Great point. Those scientists had to speed up the audio to make it audible to the human ear. You and others are hearing something that is (obviously) audible to the naked human ear. Only other thing that makes sense is if this is "hearing" inaudible frequencies through other channels to the brain other than the ear canal. Look up hearing microwaves. The earths magnetic field is pulsing at extremely low frequencies and people are not supposed to "hear" them....

I do believe that the whole body is capable of "hearing" too in as much as it can sense or feel vibration. Whether we are concious of the experience or not our body takes in and uses this information.

The sound that I have heard at least a couple of times did seem to be with the ear itself, but I would say that there was an aspect of it that was deep enough to be "felt" as well; at least the time it woke me up from a deep sleep at night. That one I would say was pretty "loud".

There was one occasion when for most of one morning I could hear a barely perceptible low rumble for hours in one area inside my house, but not outside. When I tried to point it out to a friend who happened by, he could not hear it! I thought I was going crazy.

These rumbles continue to make some of us wonder.

Puterman heard mechanical. Is there any frakking for something like natural gas in that region?

Maybe there's another unstable area getting prepared for international nuclear waste dumping.@@:

Do you know what to do if it comes to an eq? Bend over and...:

That sounds EXACTLY like what I was hearing here in Memphis weeks ago. Thanks for sharing this, I don't feel so crazy and alone.

Whats going on westcoast? Still hearing this?

reply to post by nitro67


Quakes in California and Washington. Get the info from the experts on the 2011 Earthquake thread. They are "feeling" these quakes today.

reply to post by justsaying


Yes, I am still hearing it...some days more than others. It was quite loud again yesterday although still not as loud as on the 28th.

I am in communication now with a specialist at the USGS. If I get any information I will be sure to share it with you all. Please continue to let me know of any personal experiences and things such as what time, and where you are and the direction it is coming from. I am going to try and correlate it (if possible) with the nearest seismo stations.

Quake activity is picking up a bit on our West Coast. Hopefully it will all just settle back down.

I'm hearing the intermittent rumbling again today in Arizona. Each time it happened I went outside and listened and noted the time. The rumbling was the exact same each time. Same intensity, same "direction" (SWW as far as I can tell). Each time it lasts about 5 minutes and then stops abruptly.

These are the times I have noted so far today:
9:47 am
10:18 am
10:49 am
11:35 am

So far today it seems to be happening about every 30 minutes. When I noticed this happening on Dec 15 it seemed to be happening about every 30 minutes as well.

Not sure if you all are aware of it but there is a phenomena with such sounds and hums and rumbles on the east coast as well. Several months ago I was corresponding on the forum with a very beleaguered woman in Florida who was sensing a low frequency hum or vibration that apparently her husband could not. At the time Fragile Earth was not full of such reports so a lot of us were wondering was it paranormal or a psychological issue or a medical problem. I'd been plagued with sensing jarring ultra low frequency vibrations here in MD in 2004 to 2005. In 2010 we did experience a quake with some witnesses including myself hearing some sort of shearing or ripping noise but others like my husband not hearing it. In the Carolinas Boondock Saint stated in his thread he hears some sort of deep rumbling sound. My husband and I heard what he is describing during our 2010 visit to South Carolina.

In the cases I am referencing sometimes the sounds are heard and sometimes they are sensed through the whole body. For the woman in Florida and myself there was something about them that was at odds with the body's natural rhythms so the sounds were very unsettling and disrupted sleep. A UK resident contributed to that discussion as well.

I'm guessing that whatever you're experiencing out there on the west coast has some sort of analogous phenomena here on the East Coast of the USA. I wonder how it's going for our neighbors in Cental and South America. I wonder if coastal residents in South America hear such strange things given that they have considerable seismic activity in Chile.

I have resisted commenting on this thread for sometime but since it's still moving along, here you go.

I am in next to the foothills in the Skagit Valley here in Western Washington.

Though I don't currently recall any unusual noises, I have noticed some weird movements for at least the past 6 months. There have been several times, mostly between midnight & 5AM that I've felt slight movement while lying on my back in bed. The first few times I thought we'd been having a small earthquake within a hundred miles or so, but it seemed to have occurred often enough that I began to wonder if there was a local disturbance occurring or merely that I was being hypersensitive to some truck vibrating the road from a mile away or something.

If it occurs anymore I'll try to make note of the times for future reference.

It's great to come back after a few days and actually new information still coming in from all different parts of the Country, including my own Skagit County.

I have not forgotten about this, just trying to keep my own comments constructive so as to not water things down.

I am still waiting to hear back (again) from the USGS. Just coming off the weekend though, I don't expect to get anything right away. If I am asked for more information, I will most likely being gathering all of the input from this thread, and might also have some new requests, so please check back.

The more I hear about the other stories from other areas, the more I wonder if it is from the same phenomenon. I try very hard not to jump to conclusions and that is why I am approaching this cautiously. There could be a very benign explanation. However, I don't want to make that assumption and overlook something.

Let's make sure to note weather conditions whenever we hear the rumbling, I want to make sure we can eliminate certain things, and that is one of the easiest.

Thanks again to you all for your input!!

Thanks for the kind reception of observation from other regions. I won't comment further here on east coast phenomena so as to not drag your thread off topic. Due to the things reported here on my side, I'm watching your coast with great interest and wish health and safety to you all there.

please, don't hesitate to comment and add your info. I had no idea how wide-spread this was until after I started this. I believe that it is very enlightening to know that it may perhaps be heard in other areas, and to discern if it may be the same thing or not!

Westcoast, I am sorry I have not been contributing to your thread, I do find it fascinating and I am following it day in and day out. Time has not been on my side for studies lately or even in depth conversation - on any Thread which is a major drag as I am starting to feel like a slacker! Anywho - May I sugjest an e-mail to the folks who have been studying the tremors in addition the to your inquiry to the USGS as IMO they will be the folks who will most likely have more information as to their own studies (if in fact this has to do with slow motion tremor). These slow tremors, I am sure are not just an anomaly happening only in your area, but all around the world - as all the plates are in motion. My thinking is that these studies are being conducted in your area as it is the most pronounced and the events that will occur there in the future are a concern for those that be.

Also, I am curious to know if the folks in Indonesia/Australia/Vanuatu are hearing this as well - as this is another major area where the plates are on the verge snapping again.

Best regards Westcoast and All,

Anmarie

P.S. All this makes me think of the rubbing of a wine glass - and the vibrations that occur
