Boobs don't cause Earthquakes... surpression of Jiggle Physics does. Back in the early 800s, aliens landed in a small island uncharted at the time along the coast of Africa. Claiming to be gods, the aliens shared advance technology with the natives and started barking orders. Now the aliens fancied themselves beautiful, but upon seeing us and our women they became jealous and introduced the Physics Suspender. The device emits a field that could encompass the earth that can cancel out certain aspects of Physics. Now, as I'm sure some of you are aware, boob used to act as an earthquake suppressor; absorbing all that shaking into their breasts. In order to cause havoc, the aliens commanded their subjects to use the device to surpress the Jiggle Physics and to cover their women. Soon, the aliens dies of slow oxygen poisoning and along with them the island culture died as well, but the teachings were spread by the wind and became a religion. Like a long game of telephone though it got a little skewed and lost in translation resulting in people thinking boobs, even partially uncovered cause earthquakes. But what actually happens is that they try and surpress them resulting in excess energy emitted from the boobs due to their powers being suppressed by the Physics Suspender.
So what we should really do is find this device and shut it down.
