Short term afterslip in the 1994 Sanriku‐Haruka‐Oki Earthquake

Geophysical Research Letters, 1997
The Sanriku‐Haruka‐Oki earthquake, that occurred on December 28, 1994 at the Japan Trench as a typical interplate thrust event, was followed by year‐long afterslip as large as the slip in the high‐speed rupture [Heki et al., 1997]. Here we report on the transition between these, inferred from crustal movements during the five days interval before and ...

Coseismic Slip and Early Rapid Afterslip of the 2025 MW 7.7 Myanmar Earthquake Constrained by Space‐Based Geodetic Observations

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The 2025 destructive Myanmar earthquake ruptured the previously recognized seismic gap along the Sagaing fault, with the longest ever recorded surface ruptures (∼ ${\sim} $500 km). Here, we use SAR and optical images to characterize coseismic and early postseismic deformation of this event.

Rheological and tectonic implications of eastern Tibet: Insights from early aftershock sequences driven by afterslip following three 2021–2022 moderate-large events

International Journal of Applied Earth Observations and Geoinformation
Early aftershock sequences and afterslip provide key insights into crust rheology and the triggering mechanisms of seismicity sequences. Three recent moderate-large strike-slip earthquakes in eastern Tibet, including the 2021 Yangbi Mw 6.1, the 2021 ...

Coseismic Kinematics and Early Afterslip Evolution of the 2025 Mw ${\mathbf{M}}_{\mathbf{w}}$ 7.1 Dingri Earthquake (Southern Tibet) From Space Geodesy

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The 2025 Mw ${\mathrm{M}}_{\mathrm{w}}$ 7.1 Dingri earthquake is a large normal‐faulting event within the Southern Tibet Rift System. We use space‐borne radar interferometry to investigate both coseismic rupture and ∼3‐month early afterslip. Results show that this event ruptured a west‐dipping (48°) fault, exhibiting a predominant normal dip ...

Linking Geodetically Resolved Uplift to Long‐Term Orogenic Exhumation in the Southern Alps, New Zealand

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract A limitation in our understanding of the geodynamics of orogenies is the difficulty in resolving the spatial variations in long‐term processes such as exhumation of the crust. Although geodesy can record ground motions to millimeter‐scale precision at high spatial and temporal resolutions, these observations only cover a small fraction of the ...

Implications of rate and state dependent friclion for creep on shallow faults

Annals of Geophysics, 1994
The aseismic sliding on shallow strike-slip faults, under the assumption of a non linear constitutive equation (velocity strengthening), is here treated as a two-dimensional quasi-static crack problem whose equations are solved numerically (boundary ...

Temporarily Increased Recurrence Rate of Shallow Slow Slip Events Driven by Significant Afterslip Following the 2012 Mw 7.6 Nicoya Earthquake

Geophysical Research Letters
Slow slip events (SSEs) release tectonic strain without causing sudden ground shaking. SSEs have been observed at many subduction zones, some dynamically triggered by stress changes due to the passage of seismic waves.

Early Post-Seismic Deformation Revealed After the Wushi (China) Earthquake (Mw = 7.1) Occurred on 22 January 2024

Remote Sensing
The Mw = 7.1 Wushi earthquake is the second-largest digitally recorded earthquake in the Tianshan seismic zone and provides an opportunity to explore the structural characteristics of the Tianshan seismic zone.

Heterogeneous rheology controlled postseismic deformation of the 2011 Tohoku‐Oki earthquake

Geophysical Research Letters, 2016
Using two‐dimensional finite element modeling, we reproduced the observed postseismic deformation of the 2011 Tohoku‐Oki earthquake. Our model, which accounts for the lithosphere‐asthenosphere boundary and weak zones beneath volcanoes, was able to ...

Postseismic deformation model of the 2024 Noto Peninsula earthquake, central Japan

Earth, Planets and Space
We investigated the characteristics and mechanism of postseismic deformation following the 2024 Noto Peninsula earthquake (M7.6), which occurred on January 1, 2024, in the Noto Peninsula, Japan.
