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 ...

Unravelling the contribution of early postseismic deformation using sub-daily GNSS positioning [PDF]

Scientific Reports, 2019
AbstractAfter large earthquakes, parts of the fault continue to slip for days to months during the afterslip phase, a behaviour documented for many earthquakes. Yet, little is known about the early stage, i.e., from minutes to hours after the mainshock.

Bayesian Inference of Complex Stress Evolution in Rate‐and‐State Governed Faults Constrained by Seismicity Rate Observations

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Temporal changes in seismicity rates can be conceptually understood as a response and consequence of stress changes. Dieterich (1994, https://doi.org/10.1029/93JB02581) formalized this relationship using empirically derived rate‐and‐state friction laws, and Heimisson and Segall (2018, https://doi.org/10.1029/2018JB015656) later generalized the

Coseismic and postseismic deformation of the 2011 Tohoku‐Oki earthquake constrained by GRACE gravimetry [PDF]

Geophysical Research Letters, 2012
Spaceborne gravimetry data from the Gravity Recovery And Climate Experiment (GRACE) are processed using spatio‐spectral Slepian localization analysis enabling the high‐resolution detection of permanent gravity change associated with both coseismic and postseismic deformation resulting from the great 11 March 2011 Mw 9.0 Tohoku‐Oki earthquake. The GRACE

The Overprint of Transient Rheology on Laterally Heterogeneous Viscosity: Influences on Sea‐Level Change Driven by Antarctic Ice Sheet Loss

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Through bedrock deformation, solid Earth dynamics (specifically, glacial isostatic adjustment or GIA) influences ice sheet mass balance, especially for marine‐based ice sheets like the West Antarctic ice sheet (WAIS). As ice sheets retreat, crustal uplift can help stabilize a marine based ice sheet by reducing the ice exposed at the grounding ...

Role of Slabs in Postseismic Deformation Following Deep Earthquakes

Journal of Geophysical Research: Solid Earth
Abstract The Earth's viscoelastic postseismic deformation reflects its rheological structure. Even though low‐viscosity structures, such as the asthenosphere, are often thought to dominate postseismic deformation induced by shallow earthquakes, high‐viscosity subducting slabs have also been found to considerably affect postseismic ...

A note on the assumptions made while computing the postseismic lithospheric deformation

Journal of Earth System Science, 1997
The postseismic lithospheric deformation is usually explained as viscoelastic relaxation of the coseismic stresses. In general, for computing the postseismic deformation, the shear modulus (μ) is relaxed, keeping either the bulk modulus (k) or the La’me parameter (A) fixed. It is shown that the two assumptions yield significantly different results. The

A 3D finite-element mesh for modeling large-scale surface deformation induced by subduction megathrust earthquakes: Application to Chile

Seismica
Megaearthquakes (Mw > 8) cause continental-scale, long-lasting surface deformation, mainly due to viscoelastic relaxation of the asthenosphere. To investigate the links between this deformation and the slip history along subduction interfaces—including ...

Pore-pressure diffusion controls upper-plate aftershocks of the 2014 Iquique earthquake

Nature Communications
Upper-plate aftershocks following megathrust earthquakes are particularly dangerous as they may occur close to densely populated regions. Aftershock numbers decay with time, imposing a time-dependent seismic hazard that is assessed with statistical ...

Coseismic Slip and Early Postseismic Deformation Characteristics of the 2025 Mw 7.0 Dingri Earthquake

Remote Sensing
On 7 January 2025, an Mw 7.0 earthquake struck Dingri County, Shigatse, Tibet. This was the largest event in the region in recent years. Analysis of the Dingri earthquake is urgent for understanding the coseismic slip and early postseismic deformation ...
