Non‐inertial afterslip has been inferred to occur following large earthquakes. An explanation for this slow slip phenomenon is that coseismically generated stresses induce sliding on parts of a fault surface with velocity‐strengthening frictional ...

Afterslip Moment Scaling and Variability From a Global Compilation of Estimates. [PDF]
AbstractAseismic afterslip is postseismic fault sliding that may significantly redistribute crustal stresses and drive aftershock sequences. Afterslip is typically modeled through geodetic observations of surface deformation on a case‐by‐case basis, thus questions of how and why the afterslip moment varies between earthquakes remain largely unaddressed.

AbstractAseismic afterslip has been proposed to drive aftershock sequences. Both afterslip moment and aftershock number broadly increase with mainshock size, but can vary beyond this scaling. We examine whether relative afterslip moment (afterslip moment/mainshock moment) correlates with several key aftershock sequence characteristics, including ...

Frictional Afterslip Following the 2005 Nias-Simeulue Earthquake, Sumatra [PDF]
Continuously recording Global Positioning System stations near the 28 March 2005 rupture of the Sunda megathrust [moment magnitude ( M w ) 8.7] show that the earthquake triggered aseismic frictional afterslip on the subduction megathrust, with a major fraction of this slip in the up-dip direction from ...

Fault Heterogeneity and the Connection between Aftershocks and Afterslip [PDF]
Whether aftershocks originate directly from the mainshock and surrounding stress environment or from afterslip dynamics is crucial to the understanding of the nature of aftershocks. We build on a classical description of the fault and creeping regions as two blocks connected elastically, subject to different friction laws.

Crack model of afterslip events on shallow faults [PDF]
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 ...

Afterslip (and only afterslip) following the 2004 Parkfield, California, earthquake [PDF]
An analysis of the first two years of postseismic surface deformations from GPS reveals that afterslip is the only mechanism significantly contributing to postseismic deformation following the 2004 M6 Parkfield, California earthquake. Finite element modeling shows this event to have been too small to significantly stress the lower crust and upper ...

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.
