I've always wondered if he has power over earthquakes. Any time he shows some sign of having it, it normally can be hand-waved. Like when he was on Mount Saint Helens, the shaking was caused by a huge explosion of water, not an earthquake. He also broke the bridge and the glacier by stabbing Riptide in the ground, but was that Percy, Riptide, or were the structures just easily breakable at the time?
