Seismicity in the upper plate of the Northern Chilean offshore forearc: Evidence of splay fault south of the Mejillones Peninsula
Francisco Pasten-Araya,Bertrand Potin,Sergio Ruiz,Lilly Zerbst,F. Aden-Antoniow,Kellen Azua,E. Rivera,Andreas Rietbrock,Pablo Salazar,A. Fuenzalida +9 more
TL;DR: In this article, the authors build a catalog of aftershocks of the 1995 Antofagasta earthquake (Mw 8.1) recorded by the CINCA seismic network and build a three-dimensional tomographic model to determine the physical properties of the upper plate using arrival times from the new catalog combined with other earthquakes catalogs derived from several networks deployments across the MP.

Interplay of seismic and a-seismic deformation during the 2020 sequence of Atacama, Chile.
Emilied Klein,Bertrand Potin,Francisco Pasten-Araya,Roxane Tissandier,Kellen Azua,Zacharie Duputel,C. Herrera,Luis Rivera,Jean-Mathieu Nocquet,Jean-Mathieu Nocquet,Juan-Carlos Baez,Dimitri Zigone,Raul Madariaga,Raul Madariaga,Jean-Paul Ampuero,Sergio Ruiz,Christophe Vigny +16 more
TL;DR: In this paper, the authors studied the seismic sources of the mainshock and its largest aftershocks, the afterslip they generate and their aftershock, shedding light of the spatial temporal evolution of seismic and aseismic slip during the sequence.

Along‐Dip Segmentation of the Slip Behavior and Rheology of the Copiapó Ridge Subducted in North‐Central Chile
F. Pasten‐Araya,Bertrand Potin,Kellen Azua,Miguel Sáez,F. Aden-Antoniow,Sandra Ruiz,Leoncio Cabrera,Jean-Paul Ampuero,Jean-Mathieu Nocquet,Luis Rivera,Zacharie Duputel +10 more
TL;DR: In this article , the authors studied the along-dip influence of the Copiapó ridge subduction in the Atacama region, North‐Central Chile by building a new seismicity catalog, including similar events and nonvolcanic tremors.
