Abstract

This book is devoted to diverse aspects of earthquake researches, especially to new achievements in seismicity that involves geosciences, assessment, and mitigation. Chapters contain advanced materials of detailed engineering investigations, which can help more clearly appreciate, predict, and manage different earthquake processes. Different research themes for diverse areas in the world are developed here, highlighting new methods of studies that lead to new results and models, which could be helpful for the earthquake risk. The presented and developed themes mainly concern wave's characterization and decomposition, recent seismic activity, assessment-mitigation, and engineering techniques. The book provides the state of the art on recent progress in earthquake engineering and management. The obtained results show a scientific progress that has an international scope and, consequently, should open perspectives to other still unresolved interesting aspects.

Abstract

This book is devoted to the dynamics of arc migration and amalgamation on active plate margins, and we focus on the architectural examples from the NW Pacific margin. Multidisciplinary approach pursuing the complicated tectonic processes is based on stratigraphy, sedimentology, geochemistry, and geophysics. The first chapter is dedicated to the genetic analysis of sedimentary basins in and around arc-trench systems. The following block of chapters deals with the petrological, geochemical, and rock magnetic properties of arc constituents, which inform us of the migration history of crustal blocks on oceanic plates, and spatiotemporal fluctuation in modes of subduction and stress regimes upon the Eurasian convergent margins. Our vision is finally presented as a reconstruction model of plate motion around the study area since the Cretaceous (100 Ma). Diverse contents of this book surely provide the audience with the present accomplishments of tectonic researches for active margins by Earth scientists.

Abstract

This book deals with recent developments in evolutionary models for convergent margins. Reflecting transient modes for oceanic plate convergence, such boundaries are sites of varied tectonic processes, which provoke vigorous material recycling and frequent natural disasters such as massive earthquakes and catastrophic volcanism. Therefore, the origin of their diversity has long been one of the most significant themes in Earth science. The important scientific results obtained by prominent researchers who contributed chapters to this book pave the way for further in-depth studies on mobile belt frontiers, where harsh conditions hinder efforts to understand the Earth's spatiotemporal changes.

Abstract

Cave investigation is one of the most interesting research field in natural and earth sciences, showing a rapid development with technological progress. It coincides with a number of scientific disciplines to address the early human histrory, habitats of living lives and specimens. This book will be useful to students and researchers as well as to earth scientists, archeologist, biologist, natural sciences, and other experts in a other related of disciplines. The volume consists of three sections sorted thematically, each focusing on a certain aspect. The book presents results on the determination and definition of caves discussed by means of geographic, geophysical, and geological applications. Geomorphometric analysis using GIS and laser scanning, the importance of electric tomography method in cave detection, the use of groundwater sources in agricultural areas, and the habitats of bats and species are studied on several cave studies.

Abstract

Glaciers have always played an important role in human history, and currently, they are carefully observed as climate change sentinels. Glacier melt rate is increasing, and its mass balance is continuously negative. This issue deserves accurate and in-depth studies in order to, adequately, monitor its state. This circumstance in fact endangers the water supply, affecting human settlements but also creating new environments allowing the colonization by pioneer communities and the formation of new landscapes. This book is subdivided into two main sections in order to deal with the two topics of worldwide research on glaciers and ecology in glacial environments. In the first one ""Glaciers in the World,"" several reviews and studies are collected. It is an overview of glaciers, their state, and research carried out in different continents and contexts. The second section ""Glacial Ecosystems"" focuses, on the other hand, on glacier environments and ecological researches.

Abstract

This book contains six chapters dealing with the investigation of seismic and sequence stratigraphy and integrated stratigraphy, including the stratigraphic unconformities, in different geological settings and using several techniques and methods, including the seismostratigraphic and the sequence stratigraphic analysis, the field geological survey, the well log stratigraphic interpretation, and the lithologic and paleobotanical data. Book chapters are separated into two main sections: (i) seismic and sequence stratigraphy and (ii) integrated stratigraphy. There are three chapters in the first section, including the application of sequence and seismic stratigraphy to the fine-grained shales, to the fluvial facies and depositional environments, and to the Late Miocene geological structures offshore of Taiwan. In the second section, there are three chapters dealing with the integrated stratigraphic investigation of Jurassic deposits of the southern Siberian platform, with the stratigraphic unconformities, reviewing the related geological concepts and studying examples from Middle-Upper Paleozoic successions; and, finally, with the integrated stratigraphy of the Cenozoic deposits of the Andean foreland basin (northwestern Argentina).

Abstract

Knowledge has no limits and everyone has the opportunity to gain it and expand the view and horizon of understanding. Nothing in this world remains permanent, everything changes. Hence the field of morphology of the Earth (geomorphology) provides a basis for exploring, understanding and comprehending the forms and processes that occur in our surrounding. This book presents some of the ideas and understanding about geomorphology:

Learn about the effect of deforestation and then reforestation on river channel morphology.
Understand the composite mathematical modelling for continuous simulations of hydro-geomorphological processes.
Know about the process-response models for estimation of cliff erosion and its quantitative predictions.
Grow your knowledge about various geomorphometric tools that are available in freely available GIS software.
