Delamination of southern Puna lithosphere revealed by body wave attenuation tomography
(American Geophysical Union, 2014-01)
The southern Puna Plateau has been proposed to result from a major Pliocene delamination event that has previously been inferred from geochemical, geological, and some preliminary geophysical data. Seventy-five seismic ...
Performance of tuned mass damper against structural collapse due to near fault earthquakes
(Elsevier, 2015-02)
Tuned mass dampers (TMD) are devices capable of reducing structural vibration by means of transferring energy from the protected structure to the control device. This vibration control strategy has relatively recent use ...
Efeito da rigidez de pilar parede no comportamento sísmico de edifício de concreto armado
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Civil, 2013-12-13)
The aim of this work is to study the stiffness effect of wall columns on structural behavior of reinforced concrete buildings subjected to seismic action. The premises of the Brazilian standard ABNT NBR14521:2006 were ...
Performance based assessment of reinforced concrete frames designed using eigenfrequency optimization
(Procedia Engineering, 2017)
Reinforced concrete frames (RCF) are a widely used structural system, especially in developing countries due to its economy, its capacity to withstand seismic actions and the availability of materials and construction ...
Evaluation of the seismic risk of the unreinforced masonry building stock in Antioquia, Colombia
(SPRINGER, 2017-03-01)
This paper presents the development of an exposure model for the residential building stock in Antioquia (the second most populated Department of Colombia), the development of fragility functions for unreinforced masonry ...
An 8 month slow slip event triggers progressive nucleation of the 2014 Chile megathrust
(American Geophysical Union, 2017-05-16)
The mechanisms leading to large earthquakes are poorly understood and documented. Here we characterize the long‐term precursory phase of the 1 April 2014 Mw8.1 North Chile megathrust. We show that a group of coastal GPS ...
An evaluation of the applicability of current ground-motion models to the South and Central American subduction zones
(Seismological Society of America, 2012-02)
The applicability of existing ground‐motion prediction equations (GMPEs) for subduction‐zone earthquakes is an important issue to address in the assessment of the seismic hazard affecting the Peru–Chile and Central American ...
Extension and Dynamics of the Andes Inferred From the 2016 Parina (Huarichancara) Earthquake
(American Geophysical UnionUS, 2018-09)
[EN] The Mw 6.1 2016 Parina earthquake led to extension of the south Peruvian Andes along a normal fault with evidence of Holocene slip. We use interferometric synthetic aperture radar, seismology, and field mapping to ...
Evidence of a large “prehistorical” earthquake during Inca times? New insights from an indigenous chronicle (Cusco, Peru)
(ElsevierNL, 2020-12)
A colonial chronicle written by the indigenous Peruvian author Pachacuti Yamqui Salcamaygua ([1613?]) relates a legend of the sudden appearance of a huge animal – kilometres in length and approximately 4 m in width – and ...
Coseismic and postseismic motion of a landslide: Observations,modeling, and analogy with tectonic faults
(American Geophysical UnionUS, 2014-10)
We document the first time series of a landslide reactivation by an earthquake using continuous GPS measurements over the Maca landslide (Peru). Our survey shows a coseismic response of the landslide of about 2 cm, followed ...
