Book Description
Seismology in polar regions (Arctic and Antarctic) allows us to study the static condition and high-latitude dynamics of the Earth. This book covers the recent developments in seismology in polar regions; observations and networks; international collaboration; heterogeneous structure and dynamics of the lithosphere; deep Earth's interiors observed from high latitudes; characteristics of seismicity and seismic wave propagation; and global tectonics in terms of Earth's history, including the interdisciplinary studies on the interaction between Earth's spheres. Since the International Polar Year (IPY) in 2007/2008 was the most exciting campaign launched within contemporary polar studies, this book observes recent seismological achievements by the IPY, specifically focusing on the seismic signals near the surface associated with cryosphere dynamics and evolution. Topics on cryoseismology, such as glacial earthquake activities, are viewed in terms of global warming. Moreover, observational experiments and long-term monitoring under the extreme conditions in the polar environment are also discussed.

Book Description
The importance of seismic wave research lies not only in our ability to understand and predict earthquakes and tsunamis, but it also reveals information on the Earth's composition and features in much the same way as it led to the discovery of Mohorovicic's discontinuity. As our theoretical understanding of the physics behind seismic waves has grown, physical and numerical modeling have greatly advanced and now augment applied seismology for better prediction and engineering practices. This book demonstrates the latest techniques and advances in seismic wave analysis from a theoretical approach, data acquisition and interpretation, to analyses and numerical simulations, as well as research applications. The major topics in this book cover aspects on seismic wave propagation, characteristics of their velocities and attenuation, deformation process of the Earth's medium, seismic source process and tectonic dynamics with relating observations, as well as propagation modeling of seismic waves.

Book Description
The Arctic region is the keystone to understanding the present status ofcurrently ongoing Earth systems and to predicting future imagesof our planet as viewed from northern high latitudes. The Arctic region,composed of ice-covered Arctic ocean in its center and surroundingfragmentation of the major continents, has been investigatedduring the last half century through all kinds of scientific studies:bioscience, physical sciences, geoscience, oceanography, and environmental studies, together with the technological domain. This book covers topics on the recent developments of all kinds of scientific research in and around the Arctic region, with a view to monitoring the current variations in the extreme environment, affected by remarkable changes in temperature and sea-ice extent, mass loss of ice-sheet and glaciers, and variations in marine and terrestrial ecosystems, including human activities.

Book Description
variegated seismological conditions has been accumulated. The method has been developed further in two main directions: - the perfection of the techniques and equipment of three-component field studies incorporating a continuous control of the identity of equipment both in deep boreholes and on the surface; - the creation of efficient and straightforward software for the automatic processing of PM data. Whereas the early stages of development of the method have been conspicuous chiefly by the use of polarization for the discrimination of the wave field, in recent years the emphasis shifts to the use of polarization parameters to obtain additional information about the Earth. This is especially important, as the polarization parameters are very sensitive to inhomogeneities in cross-section and enable those parameters of the Earth to be studies which cannot be obtained from kinematics. Here one should especially mention the polarization of transverse waves, which can act as one of the most reliable parameters for identifying and studying anisotropic properties of the Earth. At present various modifications of PM are being developed applicable both to uphole - (PM RW = reflected waves method, PM CDP = common-depth-point method, PM refracted-wave method, PM of regional studies utilizing earthquakes) and to downhole observations (PM VSP = vertical seismic profiling). Not all the PM modifications are developing at the same rate. The method which has up to now been developed most extenSively is PM VSP.

Book Description
The occurrence of seismic events in glaciers has been an issue in the scientific literature since the early 1950s, following the report about icequakes in Baffin Island. Targeted seismological studies were undertaken by the Polish Expedition to Spitsbergen in 1962 and then continued at various glaciers in the Arctic, Antarctic and the Alps. The author of the book has been engaged in the project since 1970; he designed the layout of observations and instrumentation. The quakes he observed were categorized into two groups: typical seismic events called icequakes, and relatively long-period events named ice vibrations. In the case of icequakes, the space-time distributions and focal parameters were determined. In the case of ice vibrations, a spectral analysis was made. The present book is a synthesis of the results obtained. There are reports that the number of seismic events in glaciers has recently grown, which may be related to changing geometry of glaciers due to changing thermal conditions.
