Postseismic deformation following the 1991 Racha, Georgia, earthquake [PDF]
Geophysical Research Letters, 2007 The 1991, Ms = 7.0 Racha earthquake is the largest ever recorded in the Caucasus Mountains. Approximately three months after this thrust‐faulting earthquake, a GPS network was set up to measure postseismic surface deformation. We present an analysis of these data, which indicate accelerated postseismic motions at several near‐field sites. We model this

Modelling of postseismic processes in subduction regions [PDF]
Geodynamics & Tectonophysics, 2012 Large intraplate subduction earthquakes are generally accompanied by prolonged and intense postseismic anomalies. In the present work, viscoelastic relaxation in the upper mantle and the asthenosphere is considered as a main mechanism responsible for the occurrence of such postseismic effects.

Kinematic Representations of Viscoelastic Postseismic Deformation [PDF]
Earth and Space ScienceAbstractFollowing large earthquakes, viscoelastic stress relaxation may contribute to postseismic deformation observed at Earth's surface. Mechanical representations of viscoelastic deformation require a constitutive relationship for the lower crust/upper mantle material where stresses are diffused and, for non‐linear rheologies, knowledge of absolute ...

Postseismic relaxation and transient creep [PDF]
Journal of Geophysical Research: Solid Earth, 2005 Postseismic deformation has been observed in the epicentral area following the 1992 Landers (M = 7.3), 1999 Chi‐Chi (M = 7.6), 1999 Hector Mine (M = 7.1), 2002 Denali (M = 7.9), 2003 San Simeon (M = 6.5), and 2004 Parkfield (M = 6.0) earthquakes. The observations consist of repeated GPS measurements of the position of one monument relative to another ...

Postseismic response of repeating aftershocks [PDF]
Geophysical Research Letters, 1998 The recurrence intervals of repeating earthquakes on the San Andreas Fault in the Loma Prieta aftershock zone follow the characteristic 1/t decay of Omori's law. A model in which these earthquakes occur on isolated patches of the fault that fail in stick‐slip with creep around them can explain this observation.

, 2018 The magnitude of postseismic slip is useful for constraining physical models of fault slip. Here we examine the postseismic slip following intermediate-magnitude (M 4 to 5) earthquakes by systematically analyzing data from borehole strainmeters in ...

Integration of InSAR time series analysis and water vapour correction for mapping postseismic deformation after the 2003 Bam (Iran) Earthquake [PDF]
, 2009 Atmospheric water-vapor effects represent a major limitation of interferometric synthetic aperture radar (InSAR) techniques, including InSAR time-series (TS) approaches (e.g., persistent or permanent scatterers and small-baseline subset).

Mechanics of coseismic and postseismic acceleration of active landslides
Communications Earth & Environment, 2023 AbstractActive slow-moving landslides exhibit very different coseismic and postseismic behaviour. Whereas some landslides do not show any postseismic acceleration, there are many that experience an increased motion in the days to weeks following an earthquake.

Postseismic coastal uplift in southern Chile
Geophysical Research Letters, 1992 Tide gage records at Puerto Montt, referenced to a mareograph in Talcahuano, indicate a large (at least 75 cm) postseismic uplift of the region following the 1960 Mw = 9.5 event. Field observations carried out in 1989 at the same locations of previous measurements in 1968 are consistent with tide gage records.
