Dizhi lixue xuebao, 2021 The 2008 MS 8.0 Wenchuan earthquake occurred in the Longmenshan fault zone, which has complex geological background, strong surface relief, and heterogeneous elastic-viscous structures; however, the seismic risk of the Longmenshan fault zone was ...

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Reliable calculations of coseismic sea‐surface deformation and stress drop are essential for understanding megathrust earthquake rupture and tsunami behavior. However, the impacts of realistic three‐dimensional (3D) structure, such as seafloor topography and structural heterogeneity, on stress‐change calculations and tsunami excitation during ...

The use of Terrestrial Laser Scanning in characterizing active tectonic processes from postseismic slip to the long term growth of normal faults [PDF]
, 2012 This thesis investigates two main hypotheses regarding uncertainty in the measurement of paleoseismic offsets used to estimate fault activity and paleoearthquake magnitudes on normal faults: (1) That variations in fault geometry have a significant effect

Coseismic sediment deformation during the 1989 Loma Prieta earthquake [PDF]
, 2008 Inelastic horizontal sediment deformation from the MS 7.1, 17 October 1989 Loma Prieta earthquake has been estimated to be on the order of 20 cm at a site in Gilroy, California, about 32 km east of the epicenter.

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract The dynamic slip behavior of faults is strongly influenced by the thermal and hydraulic properties of pore fluids, which control thermal pressurization (TP) during seismic slip. While previous experiments showed significant TP‐induced weakening in DI‐water‐saturated Groningen sandstone gouges, in situ fluids are brine or brine–gas mixtures ...

Finite fault inversion of DInSAR coseismic displacement of the 2009 L'Aquila earthquake (central Italy) [PDF]
Geophysical Research Letters, 2009 We define the geometric and kinematic characteristics of the fault activated during the Mw = 6.3, 6 April 2009 L'Aquila earthquake, from the modeling of Envisat and COSMO‐SkyMed (the first ever X‐band interferogram inverted for a coseismic dislocation study) DInSAR interferograms.

Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.Fifty years of micro‐erosion metre monitoring at Kaikōura show that the 2016 earthquake more than doubled shore platform erosion rates, transforming intertidal shore platforms into rapidly degrading supratidal marine terraces and reorganising the process and lithological controls that govern rock coast evolution.

Stress- and aftershock-constrained joint inversions for coseismic and postseismic slip applied to the 2004 M6.0 Parkfield earthquake [PDF]
, 2012 Both aftershocks and geodetically measured postseismic displacements are important markers of the stress relaxation process following large earthquakes.

Homogeneous vs heterogeneous subduction zone models: Coseismic and postseismic deformation [PDF]
, 2001 A finite-element model (FEM) incorporating geologic properties characteristic of a subduction zone is compared with FEMs approximating homogeneous elastic half-spaces (HEHS)s to investigate the effect of heterogeneity on coseismic and postseismic ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract Uplifted Pleistocene marine terraces in the Illapel area along the forearc of central Chile record spatially and temporally variable uplift rates on glacial‐cycle timescales. However, the underlying mechanisms for this uplift variability and its potential relationship with the megathrust‐earthquake cycle remain poorly understood.
