I was watching History Channel last night and they had several shows pertaining to 2012. One of the theories is that there will be a realignment of the poles when everything lines up with the center of the universe. What that means to us is that the earths mantle will shift or spin. This could cause the Calderas to erupt as well as all the volcanos, it would also put a great strain on all fault lines. And lastly the earths crust would shift as a whole in relation to the present day rotation. Then again it could be Y2K all over again.
