    Description / Table of Contents: This book describes the Mesozoic to Cenozoic evolution of the Chilean and Argentinean Andes. The book is structured from a historical perspective concentrating on specific processes explained in each chapter. The chapters cover dynamic subsidence; neotectonics; magmatism; long and short term deformation; spatial development of ancient orogenic processes that control Andean reactivations; relation between ocean bathymetry and deformation. Sources of detritus through Andean construction are discussed by specialists from both sides of the Southern Andes. This book provides up-to-date reviews, maps, evolutionary schemes and extensive reference lists useful for geoscientists and students in Earth Science fields

    Description: The updip limit of seismic rupture during a megathrust earthquake exerts a major control on the size of the resulting tsunami. Offshore Northern Chile, the 2014 Mw 8.1 Iquique earthquake ruptured the plate boundary between 19.5° and 21°S. Rupture terminated under the mid-continental slope and did not propagate updip to the trench. Here, we use state-of-the-art seismic reflection data to investigate the tectonic setting associated with the apparent updip arrest of rupture propagation at 15 km depth during the Iquique earthquake. We document a spatial correspondence between the rupture area and the seismic reflectivity of the plate boundary. North and updip of the rupture area, a coherent, highly reflective plate boundary indicates excess fluid pressure, which may prevent the accumulation of elastic strain. In contrast, the rupture area is characterized by the absence of plate boundary reflectivity, which suggests low fluid pressure that results in stress accumulation and thus controls the extent of earthquake rupture. Generalizing these results, seismic reflection data can provide insights into the physical state of the shallow plate boundary and help to assess the potential for future shallow rupture in the absence of direct measurements of interplate deformation from most outermost forearc slopes.
