Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 179.This multidisciplinary monograph provides the first modern integrative summary focused on the most spectacular active tectonic systems in North America.Encompassing seismology, tectonics, geology, and geodesy, it includes papers that summarize the state of knowledge, including background material for those unfamiliar with the region; address global hypotheses using data from Alaska; and test important global hypotheses using data from this region.It is organized around four major themes: subduction and great earthquakes at the Aleutian Arc,the transition from strike slip to accretion and subduction of the Yakutat microplate,the Denali fault and related structures and their role in accommodating permanent deformation of the overriding plate, andregional integration and large-scale models and the use of data from Alaska to address important global questions and hypotheses.The book's publication near the beginning of the National Science Foundation's EarthScope project makes it especially timely because Alaska is perhaps the least understood area within the EarthScope footprint, and interest in the region can be expected to rise with time as more EarthScope data become available.

Tectonic processes occurring in shallow subduction zones around the world generate the majority of large, damaging earthquakes. Last decade brought more understanding of these processes, showing however, their complexity and diversity from place to place. A full understanding of the seismotectonics of shallow subduction zones is yet to be achieved, however the ambitious goal of forecasting at least the largest of earthquakes is certainly worth pursuing. The present volume reports the most recent research in this field and includes theoretical as well as observational works concerning seismicity, mechanics and seismic potential of subduction segments around the world. Topics covered in Part II include new inversions for two great Alaska-Aleutians earthquakes (1957 Aleutian and 1964 Prince William Sound), seismicity trends and potential for large earthquakes in the Alaska-Aleutian region, rupture process of large earthquakes in Northern Mexico, global variability in subduction thrust zone-forearc systems, and possible causal relationship between large subduction earthquakes and volcanic eruptions. Part II is a companion volume to Part I, published in 1993.
