Disclosed are a system and method for discharging electrical potential into the earth to disable or destroy electronics and/or explosive devices. The disclosed system includes an electrical power supply providing a pulsed electrical potential exceeding 30,000 volts with at least 30 Joules of energy in each pulse. The system includes a cathode emitter and an anode emitter configured to be moved along the earth in close proximity to the earth. The electrical potential is discharged into the earth through the cathode emitter and/or the anode emitter.
