Radio is one possibility. (Some ion sources use radio waves to create a plasma), and so are x-rays, which could be produced by fast electrons accelerated by the voltages generated in the rocks...or even prompt gamma-rays resulting from absorption of neutrons created in the cracks. For that matter some neutrons could also end up being captured by gas atoms, producing short half lived radioactive gasses. Also the rupture itself could free Radon that was trapped underground.
