Crack model of afterslip events on shallow faults [PDF]

open access: yesInternational Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1992
SUMMARY Post-seismic evolution of surface displacement on a strike slip fault is studied employing a linear viscous rheology for the shallow fault zone. A mathematical model is built in which the singular integral equation governing the equilibrium of cracks is transformed in an infinite-dimensional linear symmetric system whose positive eigenvalues ...

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 slip analysis of the 2017 MW7.3 Sarpol Zahab earthquake using Sentinel-1 data

open access: yesGeodesy and Geodynamics, 2022
The MW7.3 Sarpol Zahab earthquake that occurred in the Zagros Fold-Thrust Belt (ZFTB) of Iran on November 12, 2017 is the largest earthquake instrumentally recorded in the region.

InSAR Constrained Downdip and Updip Afterslip Following the 2015 Nepal Earthquake: New Insights into Moment Budget of the Main Himalayan Thrust

open access: yesRemote Sensing, 2022
We use ALOS-2 and Sentinel-1 data spanning 2015–2020 to obtain the post-seismic deformation of the 2015 Mw 7.8 Nepal earthquake. ALOS-2 observations reveal that the post-seismic deformation was mainly distributed in four areas.

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 ...

Geodetic displacements and aftershocks following the 2001 M_w = 8.4 Peru earthquake: Implications for the mechanics of the earthquake cycle along subduction zones [PDF]

open access: yes, 2005
We analyzed aftershocks and postseismic deformation recorded by the continuous GPS station AREQ following the M_w = 8.4, 23 June 2001 Peru earthquake. This station moved by 50 cm trenchward, in a N235°E direction during the coseismic phase, and continued

Spectral-element simulations of long-term fault slip: Effect of low-rigidity layers on earthquake-cycle dynamics [PDF]

open access: yes, 2011
We develop a spectral element method for the simulation of long-term histories of spontaneous seismic and aseismic slip on faults subjected to tectonic loading.

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.

Buried shallow fault slip from the South Napa earthquake revealed by near-field geodesy. [PDF]

open access: yes, 2017
Earthquake-related fault slip in the upper hundreds of meters of Earths surface has remained largely unstudied because of challenges measuring deformation in the near field of a fault rupture.

Rapid afterslip following the 1999 Chi‐Chi, Taiwan Earthquake [PDF]

open access: yesGeophysical Research Letters, 2002
Postseismic displacements of as much as 14 cm were recorded by GPS measurements in the 3 months following the MW 7.6 1999 Chi‐Chi, Taiwan earthquake. Data from 35 continuous and 90 campaign‐surveyed stations, which show continued east over west thrusting, are analyzed to estimate the postseismic slip distribution and fault geometry.
