Seafloor observations indicate spatial separation of coseismic and postseismic slips in the 2011 Tohoku earthquake

Nature Communications, 2016
Postseismic slip of the 2011 Tohoku earthquake in Japan has occurred on the plate interface, but quantifying the slip has been difficult due to a lack of seafloor data.

Months‐Long Crustal Deformation Driven by Aseismic Slips and Pore Pressure Transients Triggered by Local and Regional Earthquakes

Geophysical Research Letters, 2021
Strong strain and pore pressure changes are observed after three Mw 4.5+ local and one Mw 7.2 regional earthquake during 2010–2017 in borehole strainmeters near Anza, California.

Insights into Very Early Afterslip Associated with the 2021 M 8.2 Chignik, Alaska Earthquake Using Subdaily GNSS Solutions

Remote Sensing, 2023
Based on subdaily kinematic GNSS solutions, the fault slip properties during the very early postseismic phase after the 2021 M 8.2 Chignik earthquake are investigated in this paper.

Fault Slip Reversals Preceded the Intraplate 2021 Earthquake Series in the Vienna Basin (Central Europe)

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Fault‐slip reversals indicate transient stress changes and may illuminate earthquake preparation processes. Here we present high‐resolution observations of sub‐millimetric creep and slip reversals on the Altaquelle Fault, a Quaternary normal fault in the southern Vienna Basin, preceding a regionally significant intraplate earthquake sequence ...

Integrated Investigation on Heterogeneous Lower Crust Rheology in Kyushu and Afterslip Behavior Following the 2016 Mw7.1 Kumamoto Earthquake

Geophysical Research Letters
The viscoelastic lower crust beneath Kyushu Island, influenced by the volcanic arc, interplays with active crustal faults in this region and helps to shape local tectonics.

Decomposition of Postseismic Signals Following ≥Mw 6 Earthquakes on Sumatra Island Based on Sumatran GPS Array (SuGAr) Observations

Journal of Geospatial Information Science and Engineering
Indonesia, located at the convergence of four major tectonic plates, experiences frequent large earthquakes, particularly in Sumatra, due to the subduction of the Indo-Australian Plate and the Sumatra Fault Zone (SFZ).

Along‐Strike Coupling Heterogeneity in Cascadia's Slow‐Slip Zone Constrained by GNSS and Reduced‐Order Rate‐And‐State Friction Modeling

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Slow slip events (SSEs) in the Cascadia subduction zone exhibit along‐strike segmentation, where the central segment has longer recurrence intervals but smaller moments. We quantify the controls on this variability by combining geodetic inter‐SSE coupling inversion with Bayesian inference of a quasi‐dynamic rate‐and‐state friction SSE‐cycle ...

Predicting Seismic Intensity Using Machine Learning With Ancillary Data: Evidence From Destructive Earthquakes in China

Engineering Reports, Volume 8, Issue 9, September 2026.
A machine learning framework integrating multisource seismic, social, and geographic data accurately predicts kilometer‐scale seismic intensity, enabling rapid postearthquake damage assessment during data‐scarce “black‐box” periods. ABSTRACT Accurate and rapid assessment of seismic intensity is crucial for postearthquake emergency response.

Mechanisms of Transient Postseismic Deformation Following the 2024 Mw 7.5 Noto Peninsula Earthquake Inferred From Horizontal and Vertical GNSS Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The 2024 Mw 7.5 Noto Peninsula earthquake provided an opportunity to investigate postseismic deformation in a tectonically complex back‐arc region in central Japan, where Miocene normal faults are reactivated under present‐day compression.

Continuous estimation of coseismic and early postseismic slip phenomena via the GNSS carrier phase to fault slip approach: a case study of the 2011 Tohoku-Oki sequence

Progress in Earth and Planetary Science, 2022
The transition process from coseismic to early postseismic phenomena within a half-day remains a significant topic for understanding the slip budget and friction properties of the fault.
