We evaluate the radiated seismic energy normalized by external work for hydraulic fracturing, beam bending, and uniaxial compression experiments conducted on Opalinus clayshale and Barre granite specimens. Results suggest that normalized radiated seismic energy is highest for the beam bending, followed by uniaxial compression, and, finally, that the hydraulic fracturing experiments radiate the least seismic energy when normalized by external work. We also find that the normalized radiated energy during tests on Opalinus clayshale is 3% to 22% of that in Barre granite across multiple loading mechanisms.
