I know this thread was started about 3 years ago, I found it last night when I kept hearing these low rumbling sounds that felt like they were coming
from the sky. But like the original poster said you can FEEL the sound. Its quite similar to thunder, but definitely not thunder, or a
plane/truck/train/engine etc. I heard it a couple nights ago but last night it lasted several hours. It isn't continuous, I think I hear them in
groups of three. They are short, only lasting a second or two, then pause.... about 45 seconds goes by, and I hear it again. My gut also told me that
its some geological, maybe seismic?
