"Advances in Seismic Event Location" provides a comprehensive overview of the fundamental aspects of seismic event localization and presents a variety of modern localization methods along with their applications across different spatial scales. The book addresses three central themes: seismic monitoring within the framework of the Comprehensive Nuclear-Test-Ban Treaty (CTBT), the localization of seismic events in three-dimensional Earth models, and methods for locating multiple events. Each chapter includes background material that allows readers to familiarize themselves with the topics discussed, as well as numerous references for further study. The focus is on recent advancements in methodology and their practical applications. The book is primarily aimed at academic and professional researchers, as well as students of seismology.
