EPIC has purchased its first fully automated seismic source, a Propelled Energy Generator, model: PEG-40Kg manufactured by R.T. Clark Companies, Inc. The system is light weight, and highly portable, and is designed to easily mount onto a truck or SUV hitch. Seismic energy is produced when  a large hammer mass weight is propelled by an elastomer band (i.e. a very large rubber band) onto an impact plate, producing an impact frequency range of 10-250Hz. The source is controlled with a hand held motor controller,  and can operate in single cycle or continuous cycle mode. The device is powered by a 12V large capacity battery (car battery).  The PEG-40Kg was received, assembled, and field-tested by  EPIC staff on June 23rd-28th, 2011.

In early May, a team from the British Broadcasting Corporation (BBC) visited New Mexico Tech to use school facilities to support a new documentary on the current state of knowledge about the Earth's core.  Since seismology is the only practical method for probing the Earth's core, the team arranged the support of two of New Mexico Tech's facilities, the Energetic Materials Research and Testing Center (EMRTC), and the Program for Array Seismic Studies of the Continental Lithosphere (EPIC), to demonstrate how the seismic waves from earthquakes or man-made explosions can travel through the Earth, and be used as a subsurface probing tool. The team was assisted by Dave Thomas and Mouse Reusch from EPIC, and Richard Aster from the NMT Earth and Environmental Science department.
