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 ...

Reconstructing the Exhumation and Paleo‐Earthquake History of a Submarine Normal Fault From Preserved Markers at the Seafloor (Roseau Fault, Lesser Antilles, France)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Assessing seismic and tsunami hazards along coastlines requires understanding past earthquakes and their recurrence along active submarine faults. Subaqueous paleoseismology commonly relies on sediment cores and seismic reflection data, but these methods may be limited by local site conditions or data quality.

Deformation Features of Coseismic Surface Rupture

, 2017
The term coseismic surface rupture is defined as a surface fracture produced by a current or large historic earthquake. The term is interchangeable with surface earthquake fault and earthquake fault in Japan, which is enhanced for the topographic morphology and geometry of surface fractures formed during large earthquakes [Research Group for Active ...

Coseismic Tectonic Surface Deformation during the 2010 Maule, Chile, M _w 8.8 Earthquake

Earthquake Spectra, 2012
Tectonic deformation from the 2010 Maule (Chile) M w 8.8 earthquake included both uplift and subsidence along about 470 km of the central Chilean coast. In the south, deformation included as much as 3 m of uplift of the Arauco Peninsula, which produced emergent marine platforms and affected ...

Linking Stress Drop and Slip Heterogeneity to Assess Source Rupture Directivity for Earthquakes in Central Italy

Terra Nova, Volume 38, Issue 3, Page 163-172, June 2026.
ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

Improved SAR Amplitude Image Offset Measurements for Deriving Three-Dimensional Coseismic Displacements

, 2015
Offsets of synthetic aperture radar (SAR) images have played an important role in deriving complete three-dimensional (3-D) surface displacement fields in geoscientific applications. However, offset maps often suffer from multiple outliers and patch-like

Does Geocentric Sea‐Level Rise in the Maritime Continent Reveal a Tectonic Fingerprint?

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The islands of the Maritime Continent are highly vulnerable to sea‐level rise driven by barystatic, sterodynamic, and vertical land motion (VLM) processes. While tectonics is known to affect relative sea‐level through VLM, its influence on long‐term geocentric sea level (GSL) through crustal deformation and gravity field perturbations remains ...

Interseismic, Coseismic, and Early Postseismic Slip Associated With the 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Unraveling the surface deformation and fault kinematics during the seismic cycle is crucial for understanding earthquake physics. Herein, we use geodetic and seismic observations to quantify the interseismic coupling, coseismic rupture, and postseismic afterslip associated with the 2025 Mw 8.8 Kamchatka earthquake.
