We performed the first demonstration of photon emission from ice during deformation and fracture. Emission of visible photons was confirmed in accordance with crack generation and fracture. Time-resolved photon emission signals are presented along with load changing. Emission intensity roughly increased with increasing strain energy released by fracture, while scattering in the intensity data showed that emission intensity was strongly dependent on thc characteristics of an individual crack. Experimental evidence indicates that the generated electric charge on crack surfaces and at crack tips should have higher energy than that of electromagnetic emissions reported by Fifolt, Petrenko and Schulson.
