Past large earthquakes influence future strong ground motion: Example of the Chilean subduction zone
(2024)
Large earthquakes in subduction zones harbor significant elastic strain accumulation duethe slip deficit (interseismic coupling), posing a major earthquake and tsunami threat tocoastal populated areas. Unlike regions that ...
Time and Space Variation of Strong Motions Parameters for Subduction Interface Earthquakes
(2017)
The strong ground motions generated by earthquakes can be related to the characteristics of the earthquakes source (stress drop, rupture velocity etc..), and therefore to the frictional conditions of the faults. These ...
How Fast Can We Reliably Estimate the Magnitude of Subduction Earthquakes?
(Blackwell Publishing Ltd, 2018)
Fast and reliable characterization of earthquakes can provide vital information to the population, even reducing the effects of strong shaking produced by them. In this study, we explore the minimum time required to estimate ...
The first since 1960: a large event in the Valdivia segment of the Chilean subduction zone, the 2016 M7.6 Melinka earthquake
(Elsevier, 2017)
We present results for joint kinematic inversion of high-rate GPS, strong motion and InSAR data for the 2016 M7.6 Melinka earthquake. We show that the source is a compact 35 s long rupture with 5.0 +/- 0.15 m of peak slip. ...
Thick, strong sediment subduction along south-central Chile anditsrole ingreat earthquakes
(Elsevier, 2020)
The south-central Chile margin experienced the largest and sixth largest earthquakes ever recorded - the 1960 Mw 9.5 Valdivia and 2010 Mw 8.8 Maule megathrust earthquakes, respectively. In early 2017, we conducted a seismic ...
Damage assessment of the 2015 Mw 8.3 Illapel earthquake in the North-Central Chile
(Springer Netherlands, 2019)
© 2018, Springer Nature B.V.Destructive megathrust earthquakes, such as the 2015 Mw 8.3 Illapel event, frequently affect Chile. In this study, we assess the damage of the 2015 Illapel Earthquake in the Coquimbo Region ...
A strong-motion database from the Peru–Chile subduction zone
(Springer, 2011)
Earthquake hazard along the Peru – Chile subduction zone is amongst the highest in the world. The development of a database of subduction-zone strong-motion recordings is, therefore, of great importance for ground-motion ...
Stochastic Generation of Accelerograms for Subduction Earthquakes
(Seismological Society of America, 2016)
The generation of accelerograms using stochastic methods has been a very useful methodology for solving the problem of the lack of appropriate strong-motion records for seismic design. Here, we propose the generation of ...
