Book Synopsis In Situ Seismic Shear-Wave Velocity Measurements and Proposed Procedures by : B. Auld
Download or read book In Situ Seismic Shear-Wave Velocity Measurements and Proposed Procedures written by B. Auld and published by . This book was released on 1978 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Determination of dynamic shear modulus in situ has been an increasingly important source of data for ground response analysis for earthquake design studies. Historically, shear modulus is calculated from in situ measurement of seismic shear-wave velocity. A downhole impact energy source has been developed which maximizes the shear-wave energy produced and minimizes compressional-wave energy for purposes of crosshole in situ seismic shear-wave velocity measurements. The geometry of the energy source permits reversal of the polarity of shear-wave arrivals without changing the polarity of compressional-wave arrivals.

Book Synopsis Generation and Measurement of Shear Waves In Situ by : RJ. Hoar
Download or read book Generation and Measurement of Shear Waves In Situ written by RJ. Hoar and published by . This book was released on 1978 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field procedures used to measure in situ shear wave velocity by cross-hole and downhole seismic methods are presented along with typical travel time records. Identification of the initial shear wave arrival is enhanced by use of a reversible torsional source in the crosshole method and a reversible embedded source in the downhole method. Correct triggering of recording equipment is critical in these measurements. Characteristics of three triggering systems--a velocity transducer, a resistance-capacitance (RC) circuit, and an electrical step trigger--are presented. Incorrect triggering can cause errors greater than 50 percent in field measurement of shear wave velocity. Other variables such as borehole casing, borehole disturbance, and source and sensor configuration also affect velocity measurement. The effects of many of the variables can be minimized by basing wave velocity computations on interval travel times of the initial arrival. It is recommended that any ASTM standards for crosshole and downhole seismic methods include field check procedures for correct timing and triggering of recording equipment and field measurement of borehole verticality.

Book excerpt: The application of shear (S) waves in seismic petroleum exploration is in a critical stage of development. This book outles the past technologies, the current ones and the possible future ones.The current efforts in S- wave exploration described in this paper consist of investigation of problems in S- wave recording for example surface wave interference, processing for example, reflectiion static time corrections and interpretation for example correlation of reflections on P- and S- wave seismic sections. It also looks at a recent development that will advance S- wave exploration considerably.

Book Synopsis Upper Mantle Shear Wave Velocity Structure of the East Anatolian-Caucasus Region by : Gleb Anatolyevich Skobeltsyn

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present dissertation, I describe two studies of the regional upper mantle shear wave velocity structure. In order to derive the absolute velocity structure of the upper mantle, I have applied surface wave tomography to model Rayleigh wave phase velocities as a function of period. Then I inverted the Rayleigh phase velocities to obtain shear wave velocities as a function of depth. The resulted high-resolution 3-D shear wave velocity model of the regional upper mantle is characterized by a better depth resolution than any preexisting tomographic models. I also conducted a shear wave splitting analysis using traditional methods and developed a two-layer grid search algorithm in order to infer the upper mantle anisotropic structure. The results of the shear wave splitting analysis for the stations located in Azerbaijan are the first in the region. My 3-D velocity model shows the depth extent of the asthenospheric layer beneath the Turkish and Iranian Plateaus, which does not exceed 200 km and therefore rejects any suggestions of the existence of deep mantle plums in the area. The deep high velocity bodies beneath the Black Sea and northern Iranian Plateau are identified as the remnant slabs of the northern and southern brbranchesf the Neo-Tethys lithosphere. The widespread volcanism and the uplift within the plateau were the result of a gradual steepening of the subducting slab of the southern branch of Neo-Tethys. The shear wave splitting analysis shows evidence of the two-layer anisotropic structure beneath the eastern Caucasus region. The results presented in the dissertation are crucial for the regional seismic hazard analysis.

Book excerpt: This full color manual is intended to explain the principles of seismic design for those without a technical background in engineering and seismology. The primary intended audience is that of architects, and includes practicing architects, architectural students and faculty in architectural schools who teach structures and seismic design. For this reason the text and graphics are focused on those aspects of seismic design that are important for the architect to know.
Book Synopsis National Earthquake Resilience by : National Research Council
Download or read book National Earthquake Resilience written by National Research Council and published by National Academies Press. This book was released on 2011-09-09 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States will certainly be subject to damaging earthquakes in the future. Some of these earthquakes will occur in highly populated and vulnerable areas. Coping with moderate earthquakes is not a reliable indicator of preparedness for a major earthquake in a populated area. The recent, disastrous, magnitude-9 earthquake that struck northern Japan demonstrates the threat that earthquakes pose. Moreover, the cascading nature of impacts-the earthquake causing a tsunami, cutting electrical power supplies, and stopping the pumps needed to cool nuclear reactors-demonstrates the potential complexity of an earthquake disaster. Such compound disasters can strike any earthquake-prone populated area. National Earthquake Resilience presents a roadmap for increasing our national resilience to earthquakes. The National Earthquake Hazards Reduction Program (NEHRP) is the multi-agency program mandated by Congress to undertake activities to reduce the effects of future earthquakes in the United States. The National Institute of Standards and Technology (NIST)-the lead NEHRP agency-commissioned the National Research Council (NRC) to develop a roadmap for earthquake hazard and risk reduction in the United States that would be based on the goals and objectives for achieving national earthquake resilience described in the 2008 NEHRP Strategic Plan. National Earthquake Resilience does this by assessing the activities and costs that would be required for the nation to achieve earthquake resilience in 20 years. National Earthquake Resilience interprets resilience broadly to incorporate engineering/science (physical), social/economic (behavioral), and institutional (governing) dimensions. Resilience encompasses both pre-disaster preparedness activities and post-disaster response. In combination, these will enhance the robustness of communities in all earthquake-vulnerable regions of our nation so that they can function adequately following damaging earthquakes. While National Earthquake Resilience is written primarily for the NEHRP, it also speaks to a broader audience of policy makers, earth scientists, and emergency managers.
