Geokinesis

Sometimes called "Terrakinesis", Geokinesis is a term used to describe the ability of some characters to move, shift, manipulate and otherwise control the very earth they stand on. These characters have full or limited control over rock, mud, crust and sometimes magnetic fields.
Some characters can only use this ability to shake and disrupt earth to cause earthquakes while others have finer control which allows them to create constructs or rapid state change such as turning rock to quicksand
