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. ...
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 ...
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 ...
Time-series analysis of earthquake sequences by means of information recognizer
(Elsevier, 2017)
Three seismic sequences of several thousand earthquakes each are analyzed by means of a tunable information recognizer known as wlzip. These sequences are different both in the geographical coverage and the time span, ...
Energy Budget of Intermediate-Depth Earthquakes in Northern Chile: Comparison With Shallow Earthquakes and Implications of Rupture Velocity Models Used
(Blackwell Publishing Ltd, 2019)
We calculate well-resolved corner frequencies and radiated energies for a set of 96 earthquakes divided into two clusters located in the same tectonic setting but with different depths in northern Chile. Fifty-three shallow ...
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 ...
Dynamic inversion of the 2015 Jujuy earthquake and similarity with other intraslab events
(Oxford University Press, 2017-05)
We study the seismic source of the 2015 (M-w 6.7) Jujuy, Argentina intermediate depth earthquake. We first constrain the fault plane by using a teleseismic inversion and by determining the aftershock distribution. Then, ...
The chilean GNSS network: current status and progress toward early warning applications
(Seismological Society of America, 2018)
Chile is one of the world's most seismically active regions and is therefore extensively studied by the earthquake sciences. The great length of the country hosts a variety of measurement systems allowing for the ...
The Chiloé Mw 7.6 earthquake of 2016 december 25 in southern Chile and its relation to the Mw 9.5 1960 valdivia earthquake
(Oxford University Press, 2018)
On 2016 December 25, an Mw 7.6 earthquake broke a portion of the Southern Chilean
subduction zone south of Chiloe Island, located in the central part of the ´ Mw 9.5 1960 Valdivia
earthquake. This region is characterized ...
Non-universal critical exponents in earthquake complex networks
(Elsevier B.V., 2018)
The problem of universality of critical exponents in complex networks is studied based on networks built from seismic data sets. Using two data sets corresponding to Chilean seismicity (northern zone, including the 2014 ...
