Silvergirl, I just read that with the earthquake back in May or April in Mexico, it has caused additional strain on faults that were not under strain before. But the earthquake and volcanic activity follow all along the west coast of South and North America.
And I too worry about Yellowstone going bonkers. They are having earthquake swarms on the northeast and eastern side regularly. I saw a movie a few years ago about Yellowstone erupting and the ending was not a happy one for anyone east of the Rockies.
What I find inexplicable is that these loud booms are being heard across the world and no one knows what they are or where they are coming from. In some places the booms are loud enough to knock pictures off of the walls and knock over china and such. Nothing is registering on the seismographs when the booms happen. The government denies any knowledge or part of being the cause of it. It is not aircraft. It is coming from within the earth. Neville, have you any ideas about these booms?
