This book is an introductory text on seismology intended for upper division undergraduates and graduate students. The book emphasises fundamental concepts and basic mathematical developments, and is intended to be 'student friendly'. The author explains the fundamental concepts in full detail with step-by-step development of the mathematics, although the book does assume a knowledge of vector and tensor analysis, calculus and ordinary and partial differential equations, as well as of fundamental physics, especially mechanics and elasticity theory. Simple examples, such as one-dimensional problems and liquid media are used as introductory topics. The book covers most of the fundamental topics in seismology, including seismic wave propagation, normal mode theory, ray theory approximation, body and surface waves, source mechanisms, kinematic and dynamic models and applications to the understanding of the structure of the Earth and seismotectonics. The book also contains appendices on useful mathematical tools and includes extensive problems.

Un sorprendente ensayo sobre la relación entre ciencia y religión.El mundo actual está profundamente influido por la ciencia y la tecnología; sin embargo, el cristianismo no acaba de integrar este campo en su formulacion de la fe. Este libro pretende ayudar al creyente a mirar la ciencia con una mentalidad abierta, dejando que ella interrogue su fe. La obra consta de cinco partes, que van acompañadas de un prologo y una util bibliografia.
