Numerical simulation of coseismic and postseismic deformation through a node-splitting algorithm: A case study of the Wenchuan earthquake

open access: yesDizhi lixue xuebao, 2021
The coseismic and postseismic effects are crucial elements in analyzing fault interactions and the regional seismic risk. In this paper, we developed a three-dimensional viscoelastic finite element code to simulate the coseismic and postseismic ...

Rupture Kinematics and Coseismic Slip Model of the 2021 Mw 7.3 Maduo (China) Earthquake: Implications for the Seismic Hazard of the Kunlun Fault

open access: yesRemote Sensing, 2021
The 21 May 2021 Maduo earthquake was the largest event to occur on a secondary fault in the interior of the active Bayanhar block on the north-central Tibetan plateau in the last twenty years.

Deformation due to the 17 August 1999 Izmit, Turkey, earthquake measured from SPOT images [PDF]

open access: yes, 2002
The geometry of the ruptured areas and the coseismic slip distribution data are key to highlighting the behavior of seismic faults. This information is generally retrieved from field investigations and geodetic measurements or synthetic aperture radar ...

Stress transfer and strain rate variations during the seismic cycle [PDF]

open access: yes, 2004
The balance of forces implies stress transfers during the seismic cycle between the elastobrittle upper crust and the viscoelastic lower crust. This could induce observable time variations of crustal straining in the interseismic period.

An aseismic slip pulse in northern Chile and along-strike variations in seismogenic behavior [PDF]

open access: yes, 2006
We use interferometric synthetic aperture radar, GPS, and seismic observations spanning 5 to 18 years to reveal a detailed kinematic picture of the spatiotemporal evolution of fault slip in a region corresponding to the 30 July 1995 M_w 8.1 subduction ...

An analytical approach to estimate curvature effect of coseismic deformations [PDF]

open access: yesGeophysical Journal International, 2016
We present an analytical approach to compute the curvature effect by the new analytical solutions of coseismic deformation derived for the homogeneous sphere model. We consider two spheres with different radii: one is the same as earth and the other with a larger radius can approximate a half-space model.

Geodetic model of the 2016 Central Italy earthquake sequence inferred from InSAR and GPS data [PDF]

open access: yes, 2017
We investigate a large geodetic data set of interferometric synthetic aperture radar (InSAR)and GPS measurements to determine the source parameters for the three main shocks of the 2016Central Italy earthquake sequence on 24 August and 26 and 30 October (

Normal fault earthquakes or graviquakes [PDF]

open access: yes, 2015
Earthquakes are dissipation of energy throughout elastic waves. Canonically is the elastic energy accumulated during the interseismic period. However, in crustal extensional settings, gravity is the main energy source for hangingwall fault collapsing ...

Complex tsunamigenic near-trench seafloor deformation during the 2011 Tohoku–Oki earthquake

open access: yesNature Communications, 2023
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 ...
