GPS Imaging of Vertical Land Motion and Earthquake Coseismic Displacements in the GPS Mega-Network [PDF]
, 2023 The Nevada Geodetic Laboratory’s (NGL) Global Positioning Systems (GPS) worldwide data holdings number nearly 21,000 GPS stations that comprise the GPS Mega-Network today. Advances in data processing software, final orbit and clock products, atmospheric

Geophysical Research Letters, 2023 Unknown seismogenic structures lurking beneath convergent margins introduce substantial uncertainty in seismic hazard assessments. In northwestern Luzon, the Mw 7.0 Abra earthquake on 27 July 2022 highlights the seismic activity along an unmapped blind ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.Abstract Fault slip inversions based on geodetic observations deepen our understanding of earthquake source processes. Previous attempts to simultaneously estimate the fault geometry and slip distribution have typically assumed a homogeneous half‐space owing to the prohibitively high computational costs of conventional numerical approaches.

Combination of coseismic displacement fields: a geodetic perspective
Annals of Geophysics, 2012 This study provides the mathematical framework for the rigorous combination of coseismic offsets observed by a global positioning system (GPS) network and investigates the results obtained on the occasion of the recent Emilia earthquakes (Italy). This seismic sequence that affected northern Italy from May 20, 2012, allowed two offset fields to be ...

Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract We investigate interseismic locking on the Kamchatka megathrust, source of the 2025 Mw 8.8 earthquake, using a data‐driven probabilistic framework. Horizontal GNSS velocities constrain a boundary element model on a triangulated megathrust geometry, while an algorithmic sampling strategy estimates the locking probability for fault elements ...

Geodesy and Geodynamics, 2022 The study of postseismic deformation is important for constraining the viscoelastic properties of the Earth and inverting the post-earthquake process. The levelling survey revealed that the area near Beichuan elevated 5.3 cm about two years after the MW7.

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract To explore mechanisms of rupture segmentation, we invert coseismic GNSS offsets for the 2025 Mw 7.6 Aomori, Japan earthquake. Our preferred curved‐fault solution images a compact thrust rupture at 25–50 km depth with peak slip ∼2.5 m near 35 km.

Estimation of Far-field Coseismic Deformation Caused by the Recent Giant Earthquakes [PDF]
, 2017 : In this paper, we estimate coseismic displacements in Vietnam caused by the 2004 Sumatra and the 2011 Tohoku earthquakes using static fault models in a layered spherical earth model.

Surface displacements of the 12 November 2017 Iran–Iraq earthquake derived using SAR interferometry [PDF]
, 2021 The 2017 Mw 7.3 Iran–Iraq earthquake occurred in the seismically less active northern Zagros Mountains. In this study, DInSAR technique is used to derive the surface displacements of the earthquake using Sentinel-1 and ALOS-2 images.

Frontiers in Earth Science, 2021 Evaluating the transfer of stresses from megathrust earthquakes to adjacent segments is fundamental to assess seismic hazard. Here, we use a 3D forward model as well as GPS and seismic data to investigate the transient deformation and Coulomb Failure ...
