It has been a couple of weeks since this all came together, but it has taken me some time to make the connections and then to decide to present it to
you all to mull it over as you do so well. I just can't keep it myself any longer....
First. It was November 27th. The day started out with the rumbling sound I have come to know so well (check out my tag line and oh-so-many-other
threads regarding the same or similar occurances). Difference was, it was LOUD. So loud, that my daughter was scared by it and my friends were
posting about it on facebook. I would like to think I brought some awareness earlier this year when it was the loudest I had EVER heard it, so I
stepped out and asked the question: "Don't you HEAR that?!" I recorded it and posted it here and on facebook. SO many of my friends DID hear it,
including a few in the 911 dispatch center (I used to be a dispatcher) that the police contacted the navy base to see if they were involved. It was
said that there were jet engines being fired off, so it was written off. I was never convinced. Okay...back to a couple of weeks ago, on Nov. 27th,
it was just about as loud again. Several people commented on it. Never got any kind of confirmation from the Oak Harbor base.
I want to stress that I have lived here in the NW corner of Washington State for over 20 years now. I can say without a doubt that it is NOT A:
Train, truck, traffic, fying airplane or other easily explained sound. I have always thought it geological in nature. The 'sound' is felt more
than heard. There is a vibration with it. Not everyone can hear it, because it is so low...but you can feel it. It is like that scary rumbling
build-up right before the shaking starts in a large quake (you know what I mean if you have experienced it) but it just stops...right before the
shaking. I could see it being a jet engine attached to the tarmac with the after-burners roaring and then cutting out (being tested)....except that I
am a good 30 miles away from the base and I had friends over 50 miles away hear/feel it, so I don't buy that.
SO...this was going on all morning on the 27th (makes the hair stand up on the back of your neck). I then had to go to Anacortes for a photo shoot (I
have started taking photos for people
) and on my way there, I noticed a nice sun dog forming. When I got out of my car at Washington Park (facing
Puget Sound) I looked up to see if the sun dog was still there. To my utter AMAZEMENT I saw not a sun halo, but an UPSIDE DOWN rainbow! It was like
half of a sun halo, but pointing the wrong way. There were no sun dog, no sun halo, nothing else. Just this anomally. I was in awe and started to
taking pictures (already had my camera in hand!) Following is the best picture of it:
I looked this up ofcourse, and discovered that is most likely an Upper Tangent
Only thing is, typically you see it 'attached' to a sun halo...but as you can see, there wasn't one. I really think this type of arc is quite rare
So the next piece to this story, was that earlier that day, when the rumbling was so loud, I pulled up GEE to see if I could spot anyting on the
siesmos...and I DID! I immediately posted about it on the PNSN facebook site and someone isolated it, ran a filter and posted a picture of it:

They then went on to explain that what was so unique about this IRIS station, is that is part of the INFRASOUND network, and that is what they believe
it was showing. Here is a link to a oh-so-interesting article about Infrasound:
THE RUMBLE OF DESTRUCTION / Infrasonic sound, too low to be heard by the human ear, may provide clues for predicting volcanoes, tornadoes and

INFRASOUND AT A GLANCE
Infrasound is a low frequency sound below the range of human hearing. It is produced by a variety of natural events - including earthquakes,
volcanoes, avalanches, severe weather, ocean waves - and some man-made sources - including aircraft and explosions. It is also used by some animal
species to communicate.
How is it different from audible sound?
One of the most interesting properties of infrasound waves is that they travel over global distances without losing their strength. So an instrument
in Colorado can detect the sound of ocean waves hitting the coast in California or the roar of a typhoon halfway around the world.
How is it detected?
Infrasound wavelengths are so long that they can be detected only by sensors that take up a large ground area.
What is it used for?
A global infrasound sensor system is being deployed to detect nuclear weapons testing. Scientists are also studying ways to use infrasound to provide
advance warning of natural disasters.

You can obviously by now see where I am going with this.....at least with the sound/seismo connection. The tangent arc?
Well...those of you that follow my posts/threads these past years know that I make of point of taking pictures of halos, sun dogs, sun pillars, etc. I
am now really thinking that this rare tangent arc and the extremely precise ATMOSPHERIC conditions requried for it to happen is all connected with
the atmospheric conditions requried for the ultra-low infrasound to be heard.
Am I making sense????
I have seen an huge increase in sun halos/dogs/pillars in conjunction with the rumbling....what I have come now to think of ultra-low/long frequency
sound being bounced off the atmosphere. I have now seen what I believe to be auditory/seismic/visual proof of the SAME thing.
So what is it? I really don't know. These sound waves can travel a LONG ways. Maybe it is connected with Japans tectonic movement? Maybe it's an
off-shore volcano erupting? Nuclear testing somewhere? The ionosphere being heated up by the compression of rocks prior to a large quake?
So let's dig in my friends. let's do some research and bring it all to the table. I just don't have the time or knowledge to do it all myself.
Later tonight I will go through my pictures and perhaps we can try and correlate the dates with tectonic activity. I was limiting myself before to
local action...but I think we need to look much wider.
I'll leave you with a link
to the tremor map. Put in 11/27/12 and you'll see there were almost 150 tremors
that day right in the middle of Puget Sound...so there is another option.
Let's have some scientific fun and perhaps finally find some answers to all these mystery rumbles being heard around the world!!!
