Elastic Fault Interactions and Earthquake Rupture Along the Southern Hellenic Subduction Plate Interface Zone in Greece
Saltogianni, Vasso; Mouslopoulou, Vasiliki; Oncken, Onno; Nicol, Andrew; Gianniou, Michail; Mertikas, Stelios (Geophysical Research Letters, 2020)The importance of splay-thrust faults in subduction seismogenesis is increasingly acknowledged; however, their elastic interaction with the plate interface remains unclear. Here, we use GPS velocities, constrained by ... -
Kinematic 3D Retro-Deformation of Fault Blocks Picked from 3D Seismics
Tanner, David C.; Lohr, Tina; Krawczyk, Charlotte M.; Oncken, Onno; Endres, Heike; Samiee, Ramin; Trappe, Henning; Kukla, Peter A. (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Movement on fault planes causes a large amount of smaller-scale deformation, ductile or brittle, in the area surrounding the fault. Much of this deformation is below the resolution of reflection seismics (i.e. sub-seismic, ... -
Role of Poroelasticity During the Early Postseismic Deformation of the 2010 Maule Megathrust Earthquake
Peña, Carlos; Metzger, Sabrina; Heidbach, Oliver; Bedford, Jonathan; Bookhagen, Bodo; Moreno, Marcos; Oncken, Onno; Cotton, Fabrice (Geophysical Research Letters, 2022-05-09)Megathrust earthquakes impose changes of differential stress and pore pressure in the lithosphere‐asthenosphere system that are transiently relaxed during the postseismic period primarily due to afterslip, viscoelastic and ... -
Slow Slip Triggers the 2018 Mw 6.9 Zakynthos Earthquake Within the Weakly Locked Hellenic Subduction System, Greece
Saltogianni, Vasso; Mouslopoulou, Vasiliki; Dielforder, Armin; Bocchini, Gian Maria; Bedford, Jonathan; Oncken, Onno (Geochemistry, Geophysics, Geosystems, 2021-11-08)Slow slip events (SSEs) at subduction zones can precede large‐magnitude earthquakes and may serve as precursor indicators, but the triggering of earthquakes by slow slip remains insufficiently understood. Here, we combine ... -
Strain Signals Governed by Frictional‐Elastoplastic Interaction of the Upper Plate and Shallow Subduction Megathrust Interface Over Seismic Cycles
The behavior of the shallow portion of the subduction zone, which generates the largest earthquakes and devastating tsunamis, is still insufficiently constrained. Monitoring only a fraction of a single megathrust earthquake ... -
Structural investigation and strain analysis of a polyphase flower structure in the Lower Saxony Basin, Germany
Wagner, Lars; Lohr, Tina; Tanner, David C.; Krawczyk, Charlotte M.; Oncken, Onno (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The Lower Saxony Basin (LSB) is a part of the post-Variscan Central European Basin System. We used a 3-D reflection seismic dataset in the northern LSB, provided by RWE-DEA AG, Hamburg (c.f. Lohr et al. submitted) for our ... -
Upper Plate Response to a Sequential Elastic Rebound and Slab Acceleration During Laboratory‐Scale Subduction Megathrust Earthquakes
Kosari, Ehsan; Rosenau, Matthias; Ziegenhagen, Thomas; Oncken, Onno (Journal of Geophysical Research: Solid Earth, 2022-09-02)An earthquake‐induced stress drop on a megathrust instigates different responses on the upper plate and slab. We mimic homogenous and heterogeneous megathrust interfaces at the laboratory scale to monitor the strain ... -
Vintage crustal-scale seismic profiling data made available for future applications: DEKORP 1984 – 1999
Kaerger, Lauretta; Stiller, Manfred; Agafonova, Tatiana; Krawczyk, Charlotte M.; Oncken, Onno; Weber, Michael (2021)The German continental seismic reflection program DEKORP (DEutsches KOntinentales Reflexionsseismisches Programm) was carried out in the years between 1984 and 1999. The aim of DEKORP was to investigate the deep crustal ...
