The book "Acoustic, Electromagnetic, Neutron Emissions from Fracture and Earthquakes" offers a comprehensive analysis of newly discovered interdisciplinary phenomena triggered by local mechanical instabilities. It specifically examines the emissions from nanoscaled mechanical instabilities such as fracture, turbulence, buckling, and cavitation. The focus is on vibrations in the terahertz frequency range and piezonuclear reactions. The authors present results from fracture experiments on natural rocks, demonstrating that terahertz vibrations can induce fission reactions in medium-weight elements, accompanied by neutron emissions. These phenomena could have far-reaching applications in areas such as earthquake prevention, climate change, energy production, and cell biology. The book also provides explanations for various scientific puzzles, including the formation of oceans and the accurate radiocarbon dating of organic materials.
