Geokinesis is the mental and/or physical ability to control/manipulate earth. Abilities can include earthquakes, fissures, rock slides, landslides, volcanic eruptions, or the ability to cause rock to shoot up from the ground.
Skeleton warriors manage to breach the borders of the camp and attack Percy Jackson. Nico di Angelo, still upset over his sister's death opens up the ground and sends the warriors into the Underworld before the fissure closes back up.
Nico creates large truck-size columns of black rock between Percy, Annabeth Chase, Rachel Elizabeth Dare, and himself to help the others escape Kronos' palace on Mount Othrys. Nico has also been shown levitating rocks and creating and vanishing structures of rock.
Percy also causes a volcanic eruption while fighting the Telekhines on Mount Saint Helena.
While traveling up Mount Diablo, Leo Valdez, Piper McLean, and Jason Grace are constantly being pulled into the ground as it forms around their feet like quick sand because of Gaea. Gaea herself also takes physical form by manipulating the earth itself to take the shape of a face or a woman wrapped in a cloak.

- It is unknown if Percy Jackson truly has some degree of this ability. The eruption he caused on Mount Saint Helens during the Battle of the Labyrinth was a result of a large explosion of water. He also makes fissures by stabbing Riptide in the ground,  but it is unknown if this was caused by Percy, Riptide, or the structure was simply weak enough to crack.
