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. ...
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, ...
Rupture processes of the 2012 September 5 Mw 7.6 Nicoya, Costa Rica earthquake constrained by improved geodetic and seismological observations
(2015-08-17)
On 2012 September 5, the anticipated interplate thrust earthquake ruptured beneath the Nicoya peninsula in northwestern Costa Rica close to the Middle America trench, with a magnitude Mw 7.6. Extensive co-seismic observations ...

Source of the 1730 Chilean earthquake from historical records: Implications for the future tsunami hazard on the coast of Metropolitan Chile
(2017)
Historical records of an earthquake that occurred in 1730 affecting Metropolitan Chile provide essential clues on the source characteristics for the future earthquakes in the region. The earthquake and tsunami of 1730 have ...
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 ...
Earthquake nests as natural laboratories for the study of intermediate-depth earthquake mechanics
The physical mechanism of intermediate-depth earthquakes is still under debate. In contrast to conditions in the crust and shallow lithosphere, at temperatures and pressures corresponding to depths > 50 km, rocks ought to ...
Global and along-strike variations of source duration and scaling for intermediate-depth and deep-focus earthquakes
The systematic behavior of earthquake rupture as a function of earthquake magnitude and/or tectonic setting is a key in our understanding of the physical mechanisms involved during earthquake rupture. Geophysical evidence ...
Rupture process of the April 24, 2017, Mw 6.9 Valparaíso earthquake from the joint inversion of teleseismic body waves and near-field data
(Elsevier B.V., 2018)
The central Chilean margin (32°–33°S) is characterized by the subduction of the Juan Fernández Ridge (JFR) beneath the continental South American plate. The JFR corresponds to a hotspot track composed by seamounts typically ...
Loreto intermediate depth earthquake of 26 May 2019 (Northeast Peru): source parameters by inversion of local to regional waveforms and strong‐motion observations
(Seismological Society of America, 2021-07-07)
The Loreto earthquake of 26 May 2019 occurred below the extreme northeast part of Peru at a depth of 140 km within the subducting Nazca plate at a distance of 700 km from the trench Peru–Chile. The orientation of the seismic ...
