About the Earth's current state:

I too have heard the rumbling noise 3 times, the first night was at the same times the earthquake in Japan hit, the second time was in the middle of the day clear skies no jets at a park with my family, there are no trains there for many many miles or airports, then I heard it the other day as well at home.
We did post here on ATS that we heard the noise, and from the beginning I told people it was because of natural (but devastating) breathing (expanding and contracting) of the Earth due to the very close distance our moon is to our planet currently. Look at the Tibetan video of the cave with the eerie sounds in it. The audio could pass as a vacuum, I wonder if we can get information if there was a change in wind or air pressure there that day? The Earth is humming there is activity like we have never seen on this planet.
