I HAVE HEARD/EXPERIENCED THIS!!!
I live in the Pacific Northwest, actually about right in the middle of those arrows on the map in the original post. I am glad that I came across
this thread, (or maybe not!) because I have experienced some similar 'sounds' lately.
It started this summer. Wierd how you get used to something and then dismiss it when no one else makes an issue out of it.
The times that I have heard it have been when sitting out in my backyard in the hot tub at night. I live almost right in the middle of Mount Baker,
Mount Raineer and Mount Saint Helens. The first time I heard the 'Rumblings', it was to the south of me, so I honestly thought Helens was
errupting. So much so, that I ran inside and pulled up the shake maps for the region. While Baker and Helens had some mild vibrations, nothing else
of note was there. By the time I went back outside, it was gone.
Another time is was to my East, so I thought it might have been coming from Baker. This was around the time that Yellowstone was so active, so I think
that's why I was immediately attributing it to a possible erruption.
I need to also point out that I went through both of Helen's erruptions and have a VERY clear memory of our house shaking and the rumbling. I have
been through several earthquakes from low mags up to the 6 mag both in california and here in washington state. I have been through many, many
powerful storms. I used to live near an airport and have been to military bases. I am familiar with all of these sounds, and I don't know what the
hell it is that I have been hearing and feeling.
The most recent was about 2 weeks ago. My husband and I were out in the hot tub, around 11 at night. (seems the most common time) It was again
coming from the south of our location. It sounded like thunder, but from a distance and longer in duration. We just kept looking at each other and
saying..."thunder?" but we both knew it wasn't thunder. It went on for probably 20-30 minutes (again, seems typical) and then was gone. We never
saw anyting in the sky to indicate a storm and I again checked USGS for quake activity, and nothing.
I am going to start documenting the times/description of the sounds. I will try to record it, but I think it might be to faint to record very well.
I have listened to the recordings on page three of this thread. There are some similarities, but those recordings are much louder and longer in
duration...but it could be what I am hearing also but only at a further distance.
I have to say that my instincts tell me it is something tectonic in nature. Something BIG resonating at a very low frequency that can be felt as well
as heard. I think it sounds like it's coming from the sky because of distance and resonance/the sound waves/vibrations bouncing back.
I will start going outside at night for the purpose of listening for this and I will make note of the time/duration/location and correlate that with
the local seismic graphs.
