Earthquakes initiation and thermal shear instability in the Hindu Kush intermediate depth nest
(AMER GEOPHYSICAL UNION, 2016)
Intermediate depth earthquakes often occur along subducting lithosphere, but despite their ubiquity the physical mechanism responsible for promoting brittle or brittle-like failure is not well constrained. Large concentrations ...
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 ...
Lessons from the 2010 Chilean earthquake and its impact on electricity supply
(IEEE, 2010)
Security of energy supply is a main concern worldwide, given the strong dependence on society functioning on its adequate delivery. Surges in fuel prices, political conflicts, wars and natural disasters threaten directly ...
Angola seismicity
(Springer Verlag, 2018-05-30)
This work describes the development of the Angolan earthquake catalog and seismicity distribution in the Southwestern African Plate, in Angola. This region is one of the least seismically active, even for stable continental ...
Relationship between subduction erosion and the up-dip limit of the 2014 Mw 8.1 Iquique earthquake
(American Geophysical Union, USA, 2021)
The aftershock distribution of the 2014 Mw 8.1 Iquique earthquake offshore northern Chile, identified from a long-term deployment of ocean bottom seismometers installed eight months after the mainshock, in conjunction with ...
Strong ground motion simulation of the 2015 Illapel earthquake using corrected empirical Green’s functions
(National Information Centre of Earthquake Engineering, 2017)
The September 16th 2015 Illapel, Chile, earthquake (Mw 8.4) generated a good set of aftershock data that enabled us to develop and to validate a model for synthetic ground motion generation. This study presents a methodology ...
Earthquakes initiation and thermal shear instability in the Hindu Kush intermediate depth nest
Intermediate depth earthquakes often occur along subducting lithosphere, but despite their ubiquity the physical mechanism responsible for promoting brittle or brittle?like failure is not well constrained. Large concentrations ...
Contrasting amount of fluids along the megathrust ruptured by the 2010 Maule earthquake as revealed by a combined analysis of aftershocks and afterslip
(Elsevier, 2016-03)
We present a novel approach combining time-variable computations of b-value and afterslip to study the postseismic activity following the Mw 8.8 Maule 2010 earthquake. We subdivided the first 392 days after the mainshock ...
Basal accretion along the south central Chilean margin and its relationship to great earthquakes
(American Geophysical Union, 2020)
The south central Chilean margin regularly produces many of the world's largest earthquakes and tsunami, including the 2010 Mw 8.8 Maule and 1960 Mw 9.5 Valdivia events. In 2017, we acquired seismic reflection data along ...
Intraplate earthquake swarm in Belo Jardim, NE Brazil: reactivation of a major Neoproterozoic shear zone (Pernambuco Lineament)
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
Intraplate earthquakes in stable continental areas have been explained basically by reactivation of pre-existing zones of weakness, stress concentration, or both. Zones of weakness are usually identified as sites of the ...
