Glacially-Triggered Faulting

Description

Glacially triggered faulting describes movement of pre-existing faults caused by a combination of tectonic and glacially induced isostatic stresses. The most impressive fault-scarps are found in northern Europe, assumed to be reactivated at the end of the deglaciation. This view has been challenged as new faults have been discovered globally with advanced techniques such as LiDAR, and fault activity dating has shown several phases of reactivation thousands of years after deglaciation ended. This book summarizes the current state-of-the-art research in glacially triggered faulting, discussing the theoretical aspects that explain the presence of glacially induced structures and reviews the geological, geophysical, geodetic and geomorphological investigation methods. Written by a team of international experts, it provides the first global overview of confirmed and proposed glacially induced faults, and provides an outline for modelling these stresses and features. It is a go-to reference for geoscientists and engineers interested in ice sheet-solid Earth interaction.

Holger Steffen is a geophysicist by training who joined the Geodetic Infrastructure Department at Lantmateriet, the Swedish Mapping, Cadastral and Land Registration Authority in 2012 after working for several years as a postdoctoral researcher at universities in Germany, Canada and Sweden. His work deals with glacial isostatic adjustment modelling, and corresponding acquisition and/or analysis of geodetic, geophysical and geologic observations. He chairs the Working Group of Geodynamics and Earth Observation of the Nordic Geodetic Commission. Odleiv Olesen is a senior researcher at the Geological Survey of Norway with forty years professional experience including management roles, extensive research and mapping activities. He has taught as an Adjunct Professor in Applied Geophysics at the Norwegian University of Science and Technology. Raimo Sutinen is a geo-consultant with forty years' experience in geoscience. He was previously a senior researcher at the Geological Survey of Finland where he managed the project 'Postglacial Faults'. He has more than sixty impact and 100 proceedings papers in remote sensing, soil physics and biogeochemistry. His recent research has focused on faults and earthquake-induced landforms.
