Postseismic Deformation Monitoring With the COSMO/SKYMED Constellation

IEEE Geoscience and Remote Sensing Letters, 2011
COSMO/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.

Vertical Postseismic Deformation of the 2019 Ridgecrest Earthquake Sequence

Journal of Geophysical Research: Solid Earth, 2022
AbstractThe 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 ...

Partitioned postseismic deformation associated with the 2009 Mw 6.3 L'Aquila earthquake surface rupture measured using a terrestrial laser scanner [PDF]

Geophysical Research Letters, 2010
Using 3D terrestrial laser scan (TLS) technology, we have recorded postseismic deformation on and adjacent to the surface rupture formed during the 6th April 2009 L'Aquila normal faulting earthquake (Mw 6.3).

Interpretation of postseismic deformation with a viscoelastic relaxation model

Journal of Geophysical Research: Solid Earth, 1980
Aleutian 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.

A plate flexure approximation to postseismic and interseismic deformation

Journal of Geophysical Research: Solid Earth, 1985
The 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.

Spherical versus flat models of coseismic and postseismic deformations

Journal of Geophysical Research: Solid Earth, 1999
We 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.

Inference of postseismic deformation mechanisms of the 1923 Kanto earthquake

Journal of Geophysical Research: Solid Earth, 2006
Coseismic slip associated with the M7.9, 1923 Kanto earthquake is fairly well understood, involving slip of up to 8 m along the Philippine Sea–Honshu interplate boundary under Sagami Bay and its onland extension. Postseismic deformation after the 1923 earthquake, however, is relatively poorly understood.

Postseismic deformation following the 1906 San Francisco earthquake

Journal of Geophysical Research: Solid Earth, 2000
We 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 ...

Short‐time postseismic deformation of 2001 Ms8.1 Kunlun (China) earthquake

Concurrency and Computation: Practice and Experience, 2010
AbstractAfter the Ms 8.1 Kunlun earthquake, postseismic displacements were resolved with GPS. The observed data showed that there were significant differences between the deformations on the south and the north sides of the Kunlun fault. In addition, it is shown that the direction of deformation on the north side shifted from westward to eastward after

Cataclastic deformation of garnet: a record of synseismic loading and postseismic creep

Journal of Structural Geology, 2002
Abstract Microstructural evidence for episodic deformation of the uppermost plastosphere related to failure of the schizosphere in major seismic events has been previously reported from the Sesia Zone, Western Alps, with inferred extraordinarily high stresses and strain rates for the early stages of creep during stress relaxation at temperatures of ...
