The second edition of Principles of Seismology has been extensively revised and updated to present a modern approach to observation seismology and the theory behind digital seismograms. It includes: a new chapter on Earthquakes, Earth's structure and dynamics; a considerably revised chapter on instrumentation, with new material on processing of modern digital seismograms and a list of website hosting data and seismological software; and 100 end-of-chapter problems. The fundamental physical concepts on which seismic theory is based are explained in full detail with step-by-step development of the mathematical derivations, demonstrating the relationship between motions recorded in digital seismograms and the mechanics of deformable bodies. With chapter introductions and summaries, numerous examples, newly drafted illustrations and new color figures, and an updated bibliography and reference list, this intermediate-level textbook is designed to help students develop the skills to tackle real research problems.

"Principles of Seismology is a comprehensive introduction covering all basic concepts and observations in seismology. This updated and extended 2nd edition has kept its emphasis on fundamental theoretical principles and observations, and is an essential reference and valuable resource as an intermediate-level text book for all students and researchers in geoscience."
– Torsten Dahm, GeoForschungsZentrum, Potsdam
"This is an excellent book that covers broad subjects with emphasis on long-lived basic principles of seismology. The recent advancement in instrumentation, computer, and high-quality data has made it very easy to perform seismological research. A downside is proliferation of black-box science without good understanding of the basic principles. This book provides all essential basic concepts and theories that are necessary to perform respectable research using modern seismological data, and is highly recommendable to the students who want to do serious research. Actually, I found it also very useful for seasoned seismologists like myself who have forgotten some basic concepts."
– Hiroo Kanamori, California Institute of Technology
"This heavily revised and updated edition of Principles of Seismology contains brand new chapters on Earthquakes and modern seismic Instrumentation. It also gives a detailed historical development on various aspects of seismology with many text and website references. An essential addition to one's library of seismology textbooks."
– Shamita Das, University of Oxford
Reviews of the first edition:
"It contains everything I would want my graduate students to have as their initial core knowledge of seismology. Udías presents theoretical concepts in a crisp and complete manner [...] an excellent, broad overview of seismology."
– Toshiro Tanimoto, Physics Today
"[...] an excellent introductory seismology text for advanced undergraduate and graduate students."
– Keith Priestley, Geological Magazine
"[...] a very good, student-friendly, textbook [...] it should be an absolute necessity on the bookshelves of seismologists for some time to come."
– G. F. Panza, Earth Science Reviews
"[...] useful new volume which will be much appreciated by students and will serve as a model for all those involved in seismology teaching."
– Giancarlo Scalera, Annali di Geofisica
"[...] a very instructive textbook with considerable attention to educational value [...] well and consistently organized, with numerous illustrations, which makes it very suitable as a textbook for introductory seismology courses."
– Hong Kie Thio, Pure and Applied Geophysics
"I do recommend this textbook for courses in seismology. The level of the book corresponds to upper division undergraduate and first year graduate students. It is a good introduction for more advanced books in seismology. Researchers will also find it useful to go back to the fundamental concepts."
