I don't know if you've noticed or not but it seems like when a major quake occurs in one area a similiar one will occur on the opposite side of the planet within several weeks.

And just in the last few weeks, there was a large earthquake in South America...

If you could squeeze the earth like a ball in your hand, it's really just a liquid filled ball with a thin shell. If something big happens on one side of it, some shock is bound to be felt on the other. Just the same, if the event isn't that big, it absorbs these shock waves. I don't think anyone can really imagine just how big of a catastrophic event could really happen on the earth, and although there is evidence of some very big ones having happened in the past, we haven't seen anything but the odd burp here and there in our recorded history.
