Constraints on fault and lithosphere rheology from the coseismic slip and postseismic afterslip of the 2006 M_w 7.0 Mozambique earthquake [PDF]

open access: yes, 2012
The 2006 M_w 7.0 Mozambique (Machaze) normal-faulting earthquake ruptured an unusually steeply dipping fault plane (~75°). The amount of slip in the earthquake decreased from depths of ~10 km toward the surface, and this shallow slip deficit was at least

Co‐ and Post‐Seismic Mechanisms of the 2020 Mw 6.3 Yutian Earthquake and Local Stress Evolution

open access: yesEarth and Space Science, 2023
The Mw 6.3 Yutian earthquake, occurred in northwestern Tibet on 25 June 2020, is one of the major events sequentially occurring in the region following the 2008 Mw 7.2, 2012 Mw 6.2, and 2014 Mw 6.9 earthquakes, and is of great significance for studying ...

Horizontal coseismic deformation of the 1999 Chi-Chi earthquake measured from SPOT satellite images: Implications for the seismic cycle along the western foothills of central Taiwan [PDF]

open access: yes, 2003
The 1999 Chi-Chi earthquake, M_w = 7.6, broke a major thrust fault along the western foothills of the Central Range of Taiwan. We have measured the horizontal coseismic displacement field by correlating optical satellite images acquired before and after ...

Unrest at Domuyo Volcano, Argentina, detected by geophysical and geodetic data and morphometric analysis [PDF]

open access: yes, 2019
New volcanic unrest has been detected in the Domuyo Volcanic Center (DVC), to the east of the Andes Southern Volcanic Zone in Argentina. To better understand this activity, we investigated new seismic monitoring data, gravimetric and magnetic campaign ...

Numerical simulation of influences of the earth medium's lateral heterogeneity on co- and post-seismic deformation

open access: yesGeodesy and Geodynamics, 2015
Many studies revealed that the Earth medium's lateral heterogeneity can cause considerable effects on the co- and post-seismic deformation field. In this study, the three-dimensional finite element numerical method are adopted to quantify the effects of ...

Interseismic coupling and seismic potential along the Central Andes subduction zone [PDF]

open access: yes, 2011
We use about two decades of geodetic measurements to characterize interseismic strain build up along the Central Andes subduction zone from Lima, Peru, to Antofagasta, Chile.

Pseudotachylyte-Mylonites Record of Transient Creep From Inter-Seismic Ductile to Co-Seismic Rupture

open access: yesFrontiers in Earth Science, 2022
Transient creep during an earthquake cycle is very important to understand the rheology of fault and deformation mechanisms in the brittle–plastic transition zone.

Active megadetachment beneath the western United States [PDF]

open access: yes, 2008
Geodetic data, interpreted in light of seismic imaging, seismicity, xenolith studies, and the late Quaternary geologic history of the northern Great Basin, suggest that a subcontinental-scale extensional detachment is localized near the Moho.

DInSAR Analysis of Ground Deformation Induced by the 2023 Al Haouz Earthquake, Morocco [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The study investigates the co-seismic ground deformation induced by the Mw 7.2 Al Haouz earthquake that occurred on September 8, 2023, in the Al Haouz region of Morocco.

Persistent elastic behavior above a megathrust rupture patch: Nias island, West Sumatra [PDF]

open access: yes, 2008
We quantify fore-arc deformation using fossil reefs to test the assumption commonly made in seismic cycle models that anelastic deformation of the fore arc is negligible.
