This book was released on 2010-11-11 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Processes of synchronization and interaction play a very special role in different physical problems concerning the dynamics of the Earth’s interior; they are of particular importance in the study of seismic phenomena, and their complexity is strongly affected by the variety of geological structures and inhomogeneities of the medium that hamper the course of these processes and their intensity. The attempt to tackle these problems is a great challenge from experimental, observational and theoretical point of view. We present in this Monograph the theoretical and experimental results achieved in the frame of the European Project “Triggering and synchronization of seismic/ acoustic events by weak external forcing as a sign of approaching the critical point” (INTAS Ref. Nr 05-1000008-7889); in this Project, which was inspired by Professor Tamaz Chelidze, our aim was to give grounds for better understanding and interpretation of dynamical interactive processes of physical ?elds, both found in the laboratory experiments as well as in ?eld observations. One of the leading problems – related to synchronization and interaction of different physical ?elds in fracture processes concerns triggering and initiation of rupture and displa- ments within the Earth interior. From this point of view, the results from laboratory studies on synchronization and interaction and those found and involved in ?eld observations, helped to improve the theoretical background. Reversely, some of the presented new theoretical approaches have served to stimulate laboratory and ?eld studies.

Download or read book Asymmetric Continuum written by Roman Teisseyre and published by Springer Science & Business Media. This book was released on 2013-09-24 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with a class of basic deformations in Asymmetric Continuum Theory. It describes molecular deformations and transport velocities in fluids, strain deformations in solids as well as the molecular transport, important in fracture processes. In solids, a separate problem relates to the displacements; their recording, e.g., by means of the seismometers, proves only the existence of the displacement derivatives and not a real displacement. However, the molecular displacements and new fracture criterion including the defect distributions and induced strains are defined in the book too. In fluids, the transport velocities and molecular strains describe the motion processes. The vortex motions are defined by means of the rotational transport; this approach leads to more complicated problems, like the turbulence phenomena. The interaction processes, including the electric and magnetic fields, and some thermodynamical problems and quantum theory analogies help to understand the extreme processes

Download or read book Geophysical Studies in the Caucasus written by Lev Eppelbaum and published by Springer Science & Business Media. This book was released on 2012-06-14 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this book is the methodology and results of integrated geophysical investigations in the Caucasian region, mainly interpretation of magnetic and gravity anomalies with utilization of a huge petrophysical database for the evaluation of geological structure and mineral resources. Relative voluminous geophysical data are useful for the Earth Sciences researchers interested in the Caucasian region (and adjacent and similar regions) characterized by complicated geological structure, inclined magnetization (polarization), uneven topography and mountain/sea transition. Examination of geophysical fields verified by super-deep wells drilling indicates that magmatic rocks of the Lesser Caucasus are extended northward under thick sedimentary cover of the Kura Depression up to the Greater Caucasus. These rocks form hidden petroleum-bearing traps of a newly identified type. On the basis of geophysical studies (mainly inexpensive magnetic and electric methods), a new copper-polymetallic province in the Greater Caucasus has been revealed. a newly developed integrated approach and special information-statistical techniques for processing and interpretation of geophysical data facilitate detection of important geological features, e.g. hidden intersections of linear structures that control location of large commercial ore and oil-and-gas deposits, as well as focuses of dangerous geodynamic events at a depth. Numerous illustrations (including colour) elucidate different problems and solutions on various scales and in diverse geological-geophysical environments. Many aspects of this book have been presented at the teaching courses for bachelors, masters and doctors at the Tel-Aviv University (Tel Aviv, Israel) and Ben-Gurion University (Be’er-Sheva, Israel). Benefits to readers are predetermined by the combination of the authors many-years personal experience in the geophysical studies of Azerbaijan and other regions of the Caucasus with the authors' knowledge of the modern level of geophysics in the world.

Download or read book The Physics of Friction and Fracture written by Elias Rafn Heimisson and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Friction and fracture processes are ubiquitous in the brittle crust. Thus understanding the physics of these processes is of paramount importance to successfully model and interpret a wide variety of geological phenomena such as seismic and volcanic activity. In this dissertation, I develop theory and models based on the current understanding of the physics of friction and fracture. These physics-based models are then applied to a broad class of problems related to dike propagation, induced and triggered seismicity, and slow slip mechanics. In order to couple together the underlying physics of friction and fracture to data and observable characteristic of transient behavior in the crust we need models and constitutive relationships. This dissertation is mainly on making this connection, the challenges involved, and comparison with observations. The first challenge addressed in this dissertation is to connect fault friction and microseismicity (Chapter 2). I use the experimentally derived theory of rate-and-state friction to compute the time to instability for a spring slider under arbitrary stressing history. This analytical result is used to describe a population of spring-sliders, which represents a population of seismic sources with varying initial conditions. This theory results in a constitutive relationship that relates to seismicity production and stressing history. The theory is extended well beyond what has been previously explored, in particular, where I account for interactions between seismic sources (Chapter 3). This new interaction theory is applied to several practical problems such as fault slip models and earthquake migration through cascading. Further applications of the theory from Chapter 2 are explored in Chapter 4. Where a physics-based model of a dike intrusion is developed and deformation and seismicity are modeled in a fully consistent manner. The results suggest that dike induced earthquakes are triggered on preexisting faults. Furthermore, the results give insight into the frictional structure of the crust, which needs to be heterogeneous to satisfy the temporal and spatial distribution of the seismicity. The last two Chapters (5 and 6) explore in more details the mechanics of faults and dike intrusions respectively and are mostly independent of other chapters. In chapter 5, I account for poroelastic coupling the nucleation of frictional instabilities. This work leads to a new novel theory of slow slip, which demonstrates that slow slip nucleates spontaneously on mildly rate-strengthening faults under certain circumstances when slip couples to normal stress perturbation. In the final chapter, I show how the growth of dikes and depressurization of magma chambers are coupled through fully coupled simulations. The simulations provide new insight into how a dike lengthens with time before finally arresting.

Download or read book Earthquake Processes Physical Modelling Numerical Simulation and Data Analysis Part I written by Mitsuhiro Matsu'ura and published by Birkhäuser. This book was released on 2012-12-06 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade of the 20th century, there has been great progress in the physics of earthquake generation; that is, the introduction of laboratory-based fault constitutive laws as a basic equation governing earthquake rupture, quantitative description of tectonic loading driven by plate motion, and a microscopic approach to study fault zone processes. The fault constitutive law plays the role of an interface between microscopic processes in fault zones and macroscopic processes of a fault system, and the plate motion connects diverse crustal activities with mantle dynamics. An ambitious challenge for us is to develop realistic computer simulation models for the complete earthquake process on the basis of microphysics in fault zones and macro-dynamics in the crust-mantle system. Recent advances in high performance computer technology and numerical simulation methodology are bringing this vision within reach. The book consists of two parts and presents a cross-section of cutting-edge research in the field of computational earthquake physics. Part I includes works on microphysics of rupture and fault constitutive laws, and dynamic rupture, wave propagation and strong ground motion. Part II covers earthquake cycles, crustal deformation, plate dynamics, and seismicity change and its physical interpretation. Topics covered in Part I range from the microscopic simulation and laboratory studies of rock fracture and the underlying mechanism for nucleation and catastrophic failure to the development of theoretical models of frictional behaviors of faults; as well as the simulation studies of dynamic rupture processes and seismic wave propagation in a 3-D heterogeneous medium, to the case studies of strong ground motions from the 1999 Chi-Chi earthquake and seismic hazard estimation for Cascadian subduction zone earthquakes.
