Seismology is the scientific study of earthquakes and the propagation of elastic waves through the Earth and other planetary bodies. This field also examines the environmental impacts of earthquakes, such as tsunamis, which result from undersea seismic events. Seismic waves, which are elastic waves that travel through both solid and liquid materials, are central to seismological research. These waves are categorized into several types, including body waves, surface waves, and normal modes. Body waves travel through the interior of materials, while surface waves propagate along the boundaries or interfaces between different materials. Normal modes represent a specific form of standing wave. This book elucidates the concepts and innovative models around prospective developments with respect to seismology. It outlines the processes and applications of the subject matter in detail. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
