Download or read book Q of the Earth written by Brian J. Mitchell and published by Springer Science & Business Media. This book was released on 1999-02-15 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Variations in seismic Q are sensitive to a much greater extent than are seismic velocity variations on factors such as temperature, fluid content, and the movement of solid state defects in the earth. For that reason an understanding of Q and its variation with position in the earth and with time should provide information on earth's tectonic evolution, as well as on aspects of its internal structure. Papers of this volume present new information on Q in the earth from several perspectives: methodology, results from global and regional observations of both body and surface waves, laboratory measurements, and theoretical understanding. The editors believe that the present volume reaches a new threshold in Q studies and that advances in data quality and methodology will spur increased interest in this difficult, but interesting field."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Available in PDF, EPUB and Kindle. Book excerpt: Variations in seismic Q are sensitive to a much greater extent than are seismic velocity variations on factors such as temperature, fluid content, and the movement of solid state defects in the earth. For that reason an understanding of Q and its variation with position in the earth and with time should provide information in earth's tectonic evolution, as well as on aspects of its internal structure. Progress in understanding Q has suffered from difficulty in obtaining reliable amplitude data at global and temporary stations. Moreover, laboratory determinations of Q, until recently, were most often made at frequencies much higher than those measured by seismologists for waves propagating through the earth. Recent advances in seismic station distribution and quality, as well as in methodology at both high and low fequencies, have greatly improved the quality of observational data available to seismologists from global stations. Concurrent advances have been made in measuring Q using laboratory samples at frequencies that pertain to the earth and in theoretical understanding of seismic wave attenuation. Papers of this volume present new information on Q in the earth from several perspectives: methodology, results from global and regional observations of both body and surface waves, laboratory measurements, and theoretical understanding. The editors believe that we have reached a new threshold in Q studies and that advances in data quality and methodology will spur increased interest in this difficult, but interesting field.

Download or read book Seismology and Structure of the Earth written by Barbara Romanowicz and published by Elsevier. This book was released on 2010-04-20 with total page 873 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treatise on Geophysics: Seismology and Structure of the Earth, Volume 1, provides a comprehensive review of the state of knowledge on the Earths structure and earthquakes. It addresses various aspects of structural seismology and its applications to other fields of Earth sciences. The book is organized into four parts. The first part principally covers theoretical developments and seismic data analysis techniques from the end of the nineteenth century until the present, with the main emphasis on the development of instrumentation and its deployment. The second part reviews the status of knowledge on the structure of the Earths shallow layers, starting with a global review of the Earth's crustal structure. The third part focuses on the Earth's deep structure, divided into its main units: the upper mantle, the transition zone and upper-mantle discontinuities, the D region at the base of the mantle, and the Earth's core. The fourth part comprises two chapters which discuss constraints on Earth structure from fields other than seismology: mineral physics and geodynamics. - Self-contained volume starts with an overview of the subject then explores each topic with in depth detail - Extensive reference lists and cross references with other volumes to facilitate further research - Full-color figures and tables support the text and aid in understanding - Content suited for both the expert and non-expert

Download or read book Q of the Earth in the 0 5 10Hz Band written by Z. A. Der and published by . This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of spectral characteristics of short period body waves using a worldwide data set indicates that the high frequency fall-off rates of body wave spectra correlate with the tectonic regime of the upper mantle structures traversed. The study also shows, in a consistent manner, that this is due to lateral variations of omega in the mantle. The magnitude of the worldwide omega variations in the mantle is of the same order as that previously observed for the United States. The internal consistency of the observations is such that crustal and site effects and instrument nonlinearity can be ruled out as factors significantly affecting the t estimates obtained.

Download or read book One Hundred Proofs That the Earth Is Not a Globe written by William Carpenter and published by Ravenio Books. This book was released on 2015-06-28 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much may be gathered, indirectly, from the arguments in these pages, as to the real nature of the Earth on which we live and of the heavenly bodies which were created for us. The reader is requested to be patient in this matter and not expect a whole flood of light to burst in upon him at once, through the dense clouds of opposition and prejudice which hang all around. Old ideas have to be gotten rid of, by some people, before they can entertain the new; and this will especially be the case in the matter of the Sun, about which we are taught, by Mr. Proctor, as follows: “The globe of the Sun is so much larger than that of the Earth that no less than 1,250,000 globes as large as the Earth would be wanted to make up together a globe as large as the Sun.” Whereas, we know that, as it is demonstrated that the Sun moves round over the Earth, its size is proportionately less. We can then easily understand that Day and Night, and the Seasons are brought about by his daily circuits round in a course concentric with the North, diminishing in their extent to the end of June, and increasing until the end of December, the equatorial region being the area covered by the Sun’s mean motion. If, then, these pages serve but to arouse the spirit of enquiry, the author will be satisfied.

Available in PDF, EPUB and Kindle. Book excerpt: Constitution of the Earth's Interior discusses the physical and evolutionary principles connecting various elements of the knowledge about structure and dynamics of the Earth's interior. This work is divided into eight chapters that primarily focus on the physical, chemical, and petrological state. This text contains general data on a general stationary model, which is described by equations of state combining the basic parameters, including pressure, temperature, density, gravity acceleration, and mineral composition within the Earth's interior. Considerable chapters concern the chemical and petrological composition of the matter in the Earth's interior. The remaining chapters describe models containing inhomogeneities used to illustrate processes connected with phase transitions. This book will be of great value to geologists, physicists, and researchers.

Book excerpt: One of The New York Times 10 Best Books of the Year National Book Award Finalist Finalist for the National Book Critics Circle John Leonard Prize Finalist for the Center for Fiction First Novel Prize Finalist for the New York Public Library's Young Lions Fiction Award National Best Seller "Splendidly imagined . . . Thrilling" --Simon Winchester "A genuine masterpiece" --Gary Shteyngart Spellbinding, moving--evoking a fascinating region on the other side of the world--this suspenseful and haunting story announces the debut of a profoundly gifted writer. One August afternoon, on the shoreline of the Kamchatka peninsula at the northeastern edge of Russia, two girls--sisters, eight and eleven--go missing. In the ensuing weeks, then months, the police investigation turns up nothing. Echoes of the disappearance reverberate across a tightly woven community, with the fear and loss felt most deeply among its women. Taking us through a year in Kamchatka, Disappearing Earth enters with astonishing emotional acuity the worlds of a cast of richly drawn characters, all connected by the crime: a witness, a neighbor, a detective, a mother. We are transported to vistas of rugged beauty--densely wooded forests, open expanses of tundra, soaring volcanoes, and the glassy seas that border Japan and Alaska--and into a region as complex as it is alluring, where social and ethnic tensions have long simmered, and where outsiders are often the first to be accused. In a story as propulsive as it is emotionally engaging, and through a young writer's virtuosic feat of empathy and imagination, this powerful novel brings us to a new understanding of the intricate bonds of family and community, in a Russia unlike any we have seen before.
