Early inhabitants along the hyperarid coastal Atacama Desert in northern Chile developed resilience strategies over 12,000 years, allowing these communities to effectively adapt this extreme environment, including impact of giant earthquakes and tsunamis. Here, we provide geoarchaeological evidence revealing a major tsunamigenic earthquake that severely affected prehistoric hunter-gatherer-fisher ~3800 years ago, causing an exceptional social disruption reflected contemporary changes...
The southernmost portion of the Liquiñe-Ofqui fault zone (LOFZ) lies within proposed slab window which formed due to oblique subduction Chile Ridge in Patagonia. Mapping paleo-surface ruptures, offsets, and lithological separations along master allowed us constrain geologic slip rates for first time with dextral 11.6-24.6 mm/year (Quaternary) 3.6-18.9 (Late-Cenozoic) respectively. We had trouble mapping LOFZ one local because a partially collapsed previously undiscovered volcanic complex,...
Abstract The intra‐arc Liquiñe‐Ofqui Fault System (LOFS) is an active transpressive fault zone located in the Patagonian Andes of Chile. In 2007, a seismic sequence occurred Aysén Fjord region Chilean Patagonia along LOFS, with M w 6.2 main earthquake that triggered dozens landslides, some which induced tsunami waves caused severe damage and casualties. Through analysis high‐resolution reflection bathymetric data, we identify six submarine faults cutting Late Quaternary postglacial...
Abstract On 16 September 2015, the Mw 8.3 Illapel megathrust earthquake broke subduction contact of Nazca plate beneath South American plate, causing unexpectedly high tsunami waves that strongly impacted coast along Coquimbo region in central–northern Chile. Here, we report results from a postearthquake and survey, evidencing complex coastal geological response driven by near trench seismic patches ruptured during this event. Systematically, run-ups, up to 10–11 m a.s.l., were measured on...
The present work proposes a baseline-free method to assess debonding on composite panels. is based regressive Gaussian processes (GP) used obtain vibration modes free of noise. A Bayesian scheme implemented allow the automatic determination model hyperparameters. estimation undamaged carried out by modifying optimal hyperparameters determined employing damaged plate. curvatures associated with are calculated as second analytical derivative kernel function GP; thus, use numerical methods...
