Earthquakes are disasters caused by seismic waves which are formed due to a sudden release of energy from the Earth’s lithosphere. This can develop into disturbances of massive magnitude resulting in substantial damage to life and property. Seismology is the study of earthquakes. It encompasses the study of diverse aspects related to earthquakes including seismicity analysis, frequency, wave nature, rupture dynamics, wave propagation, etc. It also involves evaluating earthquake aftershocks and effects using principles of subfields like paleoseismology. This book provides significant information of this discipline to help develop a good understanding of seismology and wave propagation. It also unravels the recent studies in this field and highlights the modern tools of earthquake prediction, evaluation and analysis. The book will be helpful to a broad spectrum of readers such as seismologists, geologists, engineers, researchers, academicians, experts and students associated with this discipline.
