This book presents an innovative new approach to studying source mechanisms of earthquakes, combining theory and observation in a unified methodology, with a key focus on the mechanics governing fault failures. It explains source mechanisms by building from fundamental concepts such as the equations of elasticity theory to more advanced problems including dislocation theory, kinematic models and fracture dynamics. The theory is presented first in student-friendly form using consistent notation throughout, and with full, detailed mathematical derivations that enable students to follow each step. Later chapters explain the widely-used practical modelling methods for source mechanism determination, linking clearly to the theoretical foundations, and highlighting the processing of digital seismological data. Providing a unique balance between application techniques and theory, this is an ideal guide for graduate students and researchers in seismology, tectonophysics, geodynamics and geomechanics, and a valuable practical resource for professionals working in seismic hazard assessment and seismic engineering.

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.

Solving problems is an indispensable exercise for mastering the theory underlying the various branches of geophysics. This book is a collection of nearly 200 problems in geophysics, which are solved in detail showing each step of their solution, the equations used and the assumptions made. Simple figures are also included to help students understand how to reduce a problem to its key elements. The book introduces the equations most commonly used in solving geophysical problems, and presents a series of exercises for the main, classical areas of geophysics - gravity, geomagnetism, seismology, and heat flow and geochronology. Problems range from simple exercises for the most elementary courses to more complex problems suitable for graduate-level students. This handy book is the ideal adjunct to core course textbooks on geophysical theory. It is a convenient source of additional homework and exam questions for instructors, and provides students with a practice or revision aid.

This book presents new results and data for the 1969 Saint Vincent Cape Earthquake (Mw=7.8) and tsunami. It provides key information to access the Spanish Geophysical Data National Archive Compilation and includes data-sets that range from the Azores Islands to the Iberian Peninsula.On February 28th, 1969, a large earthquake (Mw=7.8) strokes the Iberian Peninsula and northern Morocco, producing some causalities and important damage and economic losses. In this Topical volume ten papers are published, which are representative of many contributions presented at a Workshop organized by the Universidad Complutense de Madrid (Spain) and the instituto Geográfico Nacional (Madrid, Spain) on the occasion of the 50th anniversary of the 1969 earthquake. These papers cover different aspects of communications presented at the Workshop. There are two papers dedicated to tsunamis, one to Earthquake Early Warning System, one paper on lithospheric structure, three on seismicity and adata archive, three focused on the 1969 earthquake, and one of the seismic hazard. Summarizing, this topical issue present new results on the structure, seismicity, seismotectonics, seismic hazard, and geodynamics of this complex region that extends from the Azores Islands to the Iberian Peninsula.

The present topical volume presents a collection of contributions from a workshop that took place in Madrid in February 2014. Earthquake Early Warning System (EEWS) are a rather recent development in seismology that allows issue warnings to a site with a short lead-time about the impending arrival of the largest strong ground motion from an earthquake, after the first wave arrivals have been detected nearer to the source by adequate sensors. The Ibero-Mahgrebian region, containing Portugal, Spain, Morocco, Algeria and Tunisia, is subject to the occurrence of large earthquakes that may be followed by large tsunamis, as was the case of the Lisbon earthquake of 1755.
