Measuring and Modeling Viscoelastic Relaxation of the Lithosphere with Application to the Northern Volcanic Zone, Iceland [PDF]
Viscoelastic relaxation of the stress perturbation caused by an earthquake or diking event can produce measurable ground deformation over 100 km away from the source. We consider the role of viscoelastic relaxation in two different contexts.

Simulation analysis of strong earthquake magnitude in Bayankala block based on gravity observation
Based on the continuous gravity observation data of Wujiahe seismic station in Inner Mongolia, the waveform correlation between PET relative gravimeter and JCZ-1 very broadband seismometer and the physical characteristics of coseismic deformation are ...

New 2010 Maule Aftershock Catalog Reveals Structure of the Deep Subduction Interface
Abstract On 27 February 2010, a Mw 8.8 earthquake occurred near Maule in south‐central Chile. The subsequent rapid deployment of a dense network of seismic stations on land was able to capture the first year of its aftershock sequence. Here, we revisit this data set using picking Artificial Intelligence tools, a 3D velocity model of the region and ...

Crustal deformation in extensional regimes: Iceland, Nevada and SW Turkey [PDF]
In 1991 a 23-point, 30 x 25 km, GPS geodetic network was established in the Hengill ridge-ridge-transform triple junction, SW Iceland. The GPS data were processed using the Bernese V3.2 software.

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.

Using Space Geodesy to Constrain Variations in Seismogenic Behavior on Subduction Megathrusts [PDF]
The concept of seismogenic asperities and aseismic barriers has become a useful paradigm within which to understand the seismogenic behavior of major faults.

The past, present, and future of coseismic coastal deformation in Aotearoa New Zealand. [PDF]
Earthquakes can generate sudden coseismic uplift and subsidence that radically alter the landscape—this is nowhere more evident than at the coastline.

Coseismic surface‐ruptures and crustal deformations of the 2008 Wenchuan earthquake Mw7.9, China
The irregularly distributed surface fault‐ruptures of the Wenchuan earthquake spanned over 200 km along the Longmen Shan(LMS) fault zone. Through field investigations, we found over 10 coseismic surface‐ruptures, with maximum vertical displacements of approximately 6 m on the Yingxiu‐Beichuan fault and 2 m on the Guanxian‐Anxian fault; however, the ...

Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake
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 ...
