TL;DR: In this paper, the authors summarize the present knowledge on the South American hazardous faults as well as the main challenges for successful fault data incorporation into seismic hazard models, concluding that some of these structures constitute significant hazard sources for many urban areas and critical facilities and should be incorporated in seismic hazard assessments.

TL;DR: In this paper, 14C dating of the Mera plateau erosion surface and of the upper Pastaza terraces indicates that the minimum average incision rate since ∼18,000 years BP varies locally in the upper pastaza valley from 0.5 to 0.67 cm year−1, increasing from ∼18k BP to now, and a comparison of these incision rates with fold-and-thrust fault uplift rates indicates that incision in the Upper Pastaza valley was a result of rapid uplift (up to 1 cm year −1) along the Mir

A comprehensive database of active and potentially-active continental faults in Chile at 1:25,000 scale
TL;DR: In this article, the authors present a comprehensive database of active and potentially-active continental faults in Chile based on existing studies and new mapping at 1:25,000 scale using geologic and geomorphic criteria and digital elevation models derived from TanDEM-X and LiDAR data.
Unconformity development in retroarc foreland basins: implications for the geodynamics of Andean-type margins
TL;DR: In this paper, the authors explore the genesis of long duration (>1-20 Myr) unconformities and condensed stratigraphic sections by considering modern and ancient examples from the Andes.

Long‐Term Lithospheric Strength and Upper‐Plate Seismicity in the Southern Central Andes, 29°–39°S
TL;DR: In this paper , the authors examined the relationship between the mechanical strength of the lithosphere and the distribution of seismicity within the overriding continental plate of the southern Central Andes (SCA, 29°−39°S), where the oceanic Nazca Plate changes its subduction angle between 33°S and 35°S, from subhorizontal in the north (<5°) to steep in the south (∼30°).

TL;DR: In this article, the authors explore the coastal morphology along an uplifting 500 km-long coastal segment of the Central Andes, between the cities of Chala (Peru) and Arica (Chile).

Present‐day plate motions
TL;DR: In this article, a data set comprising 110 spreading rates, 78 transform fault azimuths and 142 earthquake slip vectors was inverted to yield a new instantaneous plate motion model, designated RM2.

TL;DR: In this paper, the authors show that tectonic segmentation of the Andes coincides with the subducted Nazca plate, which has nearly horizontal segments and 30° east-dipping segments.

Tectonics of the Caribbean and Middle America Regions from Focal Mechanisms and Seismicity
Peter Molnar,Lynn R. Sykes +1 more
TL;DR: In this article, the authors determined the relative motion of the Cocos plate and the Caribbean plate with respect to the surrounding regions or plates and determined the focal mechanisms of 70 earthquakes in these regions.

The Pampean flat-slab of the Central Andes
TL;DR: In this article, the authors studied the orogenic effects of flat subduction in an active convergent margin in the Pampean segment of Argentina and Chile (27°00′ −33°30′S) and found that the main deformation phases and uplift of the thin and thick-skinned fold and thrust belts of the principal and frontal Cordilleras of the Sierras Pampeanas occurred between 20 and 8.6 Ma.

TL;DR: The El Misti volcano as discussed by the authors has been known to produce pyroclastic-flow deposits and tephra-fall and surge deposits at an average eruption rate of 0.63 km3/k.y.
