Rock Spectral Radiation Signatures Under Different Pressures

In the past ten years, some scholars at home and abroad have conducted dozens of experiments of rock fracture. In the experiments they all observed various electromagnetic radiations, from low-frequency to radio-wave appearing in rock fracture. This observation will help us explore the new precursor of an earthquake. Now remote sensing technique has been widely applied in numerous departments of national economy such as resource exploration, environmental science, and significant results have been achieved
