Vertical Postseismic Deformation of the 2019 Ridgecrest Earthquake Sequence
Journal of Geophysical Research: Solid Earth, 2022AbstractThe 2019 Ridgecrest conjugate Mw6.4 and Mw7.1 events resulted in several meters of strike‐slip and dip‐slip along an intricate rupture, extending from the surface down to 15 km. Now with >2 years of post‐rupture observations, we utilize these results to better understand vertical postseismic deformation from the Ridgecrest sequence and ...

Postseismic deformation after 2008 Wenchuan Earthquake
Survey Review, 2014AbstractApparent postseismic deformation was observed after the 2008 Wenchuan earthquake, China. The displacement in the direction normal to the fault decays to nearly zero after 2013, but the significant dextral movement did not decay obviously during our observation of up to May 2013.

The role of rheological heterogeneities in postseismic deformation
2022<p>Advances in modelling and access to InSAR and GNSS observations have highlighted the role that rheological heterogeneities play in postseismic deformation. Here we discuss three recent studies (Muto et al. 2019, Sambuddha et al. 2022, and Takada et al.

Postseismic Deformation Monitoring With the COSMO/SKYMED Constellation
IEEE Geoscience and Remote Sensing Letters, 2011COSMO/SKYMED is currently the unique constellation of synthetic aperture radar (SAR) sensors operative, which is also for civilian use. On April 6, 2009, an Mw 6.3 earthquake struck the city of I'Aquila in Central Italy. The constellation acquired data stacks over the hit area at an unprecedented temporal rate.

Postseismic deformation following the 1906 San Francisco earthquake
Journal of Geophysical Research: Solid Earth, 2000We have reevaluated triangulation data from northern California following the 1906 San Francisco earthquake, thereby increasing the temporal and spatial resolution of postseismic deformation following that event. We have calculated uniform shear strain rates and average station velocities at Point Arena using data from 1906–1907, 1929–1930, and 1973 ...

A plate flexure approximation to postseismic and interseismic deformation
Journal of Geophysical Research: Solid Earth, 1985The rather large postseismic deformation that is associated with two‐dimensional dip‐slip faulting in the lithosphere is related to the bending of a free plate generated by dip‐slip faulting. In the absence of gravity, asthenosphere relaxation eventually permits the faulted lithosphere to assume the dihedral configuration of a faulted free plate.

Interpretation of postseismic deformation with a viscoelastic relaxation model
Journal of Geophysical Research: Solid Earth, 1980Aleutian tide gages registered coseismic subsidence of 10–15 cm at three locations during the great earthquakes of 1957 and 1965. For approximately 5–6 years after this initial subsidence the data indicate postseismic uplift of the islands to approximately their initial level.

Decadal Viscoelastic Postseismic Deformation of the 1964 Mw9.2 Alaska Earthquake
Journal of Geophysical Research: Solid Earth, 2020AbstractViscoelastic postseismic deformation after the 1964 Mw9.2 Alaska earthquake extends thousands of kilometers from the rupture region and lasts for decades, providing unique opportunities to better understand the three‐dimensional rheological properties of the Alaska subduction zone.

Spherical versus flat models of coseismic and postseismic deformations
Journal of Geophysical Research: Solid Earth, 1999We perform an exhaustive study of coseismic and postseismic surface deformations induced by shear dislocations using flat and spherical Earth models. Our aim is to examine the effects of the spherical geometry, the vertical layering, and the self‐gravitation on surface displacement field.

Andaman Postseismic Deformation Observations: Still Slipping after All These Years?
Bulletin of the Seismological Society of America, 2012More than six years after the great ( M w 9.2) Sumatra–Andaman earthquake, postevent processes responsible for relaxation of the coseismic stress change remain controversial. Modeling of Andaman Islands Global Positioning System (GPS) displacements indicated early near‐field motions were dominated by slip down‐dip of the rupture, but various ...
