Frictional Afterslip Following the 2005 Nias-Simeulue Earthquake, Sumatra [PDF]
Science, 2006 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 ...

On the mechanics of earthquake afterslip
Journal of Geophysical Research: Solid Earth, 1991 We propose a model for earthquake afterslip based on rate and state variable friction laws. In the model, afterslip is attributed to the interaction of a velocity‐weakening region at depth (within which earthquakes nucleate) with an upper region of velocity‐strengthening frictional behavior.

Geometric Moment Modulated and Maximum Entropy Informed Earthquake + Afterslip Sequences
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Synthetic earthquake sequences may be of interest for comparisons with seismicity and afterslip evolution from instrumental observations and deeper time paleoseismic event histories, as well as for forecasting purposes. Here, we describe a constructed method, independent of continuum mechanics, for generating long‐duration earthquake and ...

Fault Heterogeneity and the Connection between Aftershocks and Afterslip [PDF]
Bulletin of the Seismological Society of America, 2019 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.

Geophysical Research LettersNon‐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 ...

Geophysical Research Letters, 2012 Prior to the 2011 M9 Tohoku‐oki earthquake, subduction at the Japan Trench was characterized by M7‐8 earthquakes, sometimes rupturing the same source regions (seismic asperities), followed by extensive afterslip detected by GPS measurements. A physically‐

Early aftershocks and afterslip surrounding the 2015 Mw 8.4 Illapel rupture [PDF]
Earth and Planetary Science Letters, 2017 On 16 September 2015, the Mw 8.4 Illapel earthquake ruptured a section of the subduction thrust on the west coast of central Chile. The mainshock was followed by numerous aftershocks including some normal-faulting events near the trench. We apply a template matching approach to improve the completeness of early aftershocks within one month of the ...

Time-dependent distributed afterslip on and deep below the Izmit earthquake rupture
, 2002 Surface deformation transients measured with the Global Positioning System during the 87 days between the 17 August 1999 Izmit earthquake and the 12 November 1999 Duzce earthquake indicate rapidly decaying aseismic fault slip on and well below the coseismic rupture.
