Statistics of major Chilean earthquakes recurrence
(Springer, 2012-06)
In this work, we consider historical earthquakes registered in Chile (from 1900 up to 2010) with epicenters located between 19 and 40°S latitude, in order to evaluate the probabilities of the occurrence of strong earthquakes ...
Viscoelastic Effects in Avalanche Dynamics: A Key to Earthquake Statistics
(American Physical Society, 2014-05)
In many complex systems a continuous input of energy over time can be suddenly relaxed in the form of avalanches. Conventional avalanche models disregard the possibility of internal dynamical effects in the interavalanche ...
Modern crustal seismicity in the northern Andean Precordillera, Argentina
(Elsevier Science, 2019-04)
The Precordillera in the Andean backarc region of Argentina has a long record of large and damaging earthquakes in the last century. Its northern part is not well known seismically neither its style of deformation. In this ...
Tree-ring correlations suggest links between moderate earthquakes and distant rockfalls in the Patagonian Cordillera
(Nature Publishing Group, 2019-12)
Earthquakes with magnitudes M > 7 can trigger large landslides and rockfalls at epicenter distances of up to 400 km, whereas moderate shaking (M = 5?7) is generally thought to result in abundant co-seismic mass movements ...
Reviewing megathrust slip behavior for recent Mw > 8.0 earthquakes along the Peru-Chilean margin from satellite GOCE gravity field derivatives
(Elsevier Science, 2019-10-20)
The characterization of a seismogenic zone associated with the rupture process that occurs during great megathrust earthquakes has been approached from different perspectives. Different studies lightened the structural ...
Earthquake deformation in the northwestern Sierras Pampeanas of Argentina based on seismic waveform modelling
(Pergamon-Elsevier Science Ltd, 2011-04)
We investigate the seismic properties of modern crustal seismicity in the northwestern Sierras Pampeanas of the Andean retroarc region of Argentina. We modelled the complete regional seismic broadband waveforms of two ...
Anomalously deep earthquakes related to the Ojo de Agua Lineament and its tectonic significance, Sierras Pampeanas of Córdoba, Central Argentina
(KeAi Communications Co., 2018-01)
The Sierras de Córdoba are the easternmost uplifted ranges of the Sierras Pampeanas geological province of Argentina. They are composed of a Neoproterozoic–Paleozoic basement arranged in north–south aligned mountain ranges, ...
Rupture area analysis of the Ecuador (Musine) Mw = 7.8 thrust earthquake on April 16, 2016, using GOCE derived gradients
(KeAi Communications, 2017-01)
The Ecuador Mw = 7.8 earthquake on April 16, 2016, ruptured a nearly 200 km long zone along the plate interface between Nazca and South American plates which is coincident with a seismic gap since 1942, when a Mw = 7.8 ...
Static Stress Increase in the Outer Forearc Produced by MW 8.2 September 8, 2017 Mexico Earthquake and its Relation to the Gravity Signal
(Birkhauser Verlag Ag, 2018-08)
An Mw 8.2 earthquake affected on September 8, 2017 the Cocos plate beneath the Caribbean plate next to the transform contact with the North American plate across the Tehuantepec gap, one of the two gaps that exist along ...
Waveform inversion and focal mechanisms of two weak earthquakes in Cordillera Principal (Argentina) between 35° and 35.5° S
(Pergamon-Elsevier Science Ltd, 2016-11)
Only few (six) focal mechanism, in CMT Catalog, have been so far known for intraplate shallow events in the Andean chain close to Chile–Argentina state border at latitudes ∼35° S. We add two more mechanisms, depths and ...
