Excess strain in the Echigo plain sedimentary basin, NE Japan: Evidence from coseismic deformation of the 2011 Tohoku-oki earthquake [PDF]
Coseismic deformation depends on both the source fault and on the elastic properties of the crust. Large coseismic deformation associated with the 2011 Mw 9.0 Tohoku-oki earthquake enabled us to investigate strain anomalies from crustal inhomogeneity ...

A hybrid spectral and finite element method for coseismic and postseismic deformation
Abstract We investigate the elastic and viscoelastic responses of the Earth to a sudden slip along a fault. Firstly, equations describing the Earth’s infinitesimal deformations for elastic and viscoelastic rheological models are introduced within the weak formulation and the theorems of existence and uniqueness of solutions are demonstrated.

Recent advances of computing coseismic deformations in theory and applications [PDF]
This paper reviews the recent advances in computing coseismic deformations, and their contributions to seismology and geodesy. At first, an overview on the history of the dislocation theory development is given in the introduction section. Then, emphasis are given on some new developments through few examples in the following sections, such as the new ...

GRACE detects coseismic and postseismic deformation from the Sumatra‐Andaman earthquake [PDF]
We show that spherical harmonic (SH) solutions of the Gravity Recovery and Climate Experiment (GRACE) are now of sufficient quality to observe effects of co‐seismic and post‐seismic deformation due to the rupture from the Mw = 9.3 Sumatra‐Andaman earthquake on December 26, 2004, and its companion Nias earthquake (Mw = 8.7) on March 28, 2005.

Complex tsunamigenic near-trench seafloor deformation during the 2011 Tohoku–Oki earthquake
The near-trench coseismic rupture behaviour of the 2011 Tohoku–Oki earthquake remains poorly understood due to the scarcity of near-field observations. Differential bathymetry offers a unique approach to studying offshore coseismic seafloor deformation ...

An earthquake of moderate magnitude (MW 6.1) occurred in Yangbi County, Dali, Yunnan Province, China, on 21 May 2021. Compared to strong earthquakes, the measurement of the deformation fields of moderate earthquakes is more susceptible to errors ...

Coseismic Slip Model of the 2021 Maduo Earthquake, China from Sentinel-1 InSAR Observation
The 2021 Maduo earthquake occurred in the interior of the Bayan Har block of the Tibetan Plateau. We used space-born radar interferometry to study the coseismic deformation of this earthquake.

A Phase‐Field Model for Quasi‐Dynamic Rupture Nucleation and Propagation of In‐Plane Faults
ABSTRACT Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of fault zones. The phase‐field method has recently enabled unified modeling of fault propagation and off‐fault damage within a fracture‐mechanics‐based framework ...

The use of Terrestrial Laser Scanning in characterizing active tectonic processes from postseismic slip to the long term growth of normal faults [PDF]
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

Forecasting Cascading and Compounding Flood Risk From Earthquake‐Induced Ground Deformation
ABSTRACT Large earthquakes can disrupt river systems and produce abrupt, unforeseen changes in flood risk. Forward modelling of earthquake‐related surface deformation and its influence on inundation extent, depth, and frequency enables pre‐emptive assessment of exposure to this compound hazard.
