Integration of Field Observations With Forward and Inverse Modeling for Tsunami Reconstructions Along the Fjord‐Dominated Coastlines of Northern Cascadia

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Forward and inverse modeling techniques are often applied to paleotsunamis to reconstruct inundation parameters. The accuracy of both types of models can be influenced by geomorphology, particularly in areas such as northern Cascadia, where rocky headlands and fjords influence tsunami flow and the preservation of sedimentary deposits ...

Interseismic Creep Along the Enriquillo–Plantain Garden Fault, Haiti, Estimated From InSAR

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Enriquillo–Plantain Garden fault zone (EPGFZ) is a major left‐lateral strike‐slip fault in southern Haiti hosting several recent destructive earthquakes, including the 2021 MW 7.1 Nippes event with primary thrust‐slip. To investigate how strain is accommodated in the vicinity of the 2021 event, we analyzed Sentinel‐1 interferometric ...

Coseismic gravity and displacement changes of Japan Tohoku earthquake (Mw 9.0)

Geodesy and Geodynamics, 2016
AbstractThe greatest earthquake in the modern history of Japan and probably the fourth greatest in the last 100 years in the world occurred on March 11, 2011 off the Pacific coast of Tohoku. Large tsunami and ground motions caused severe damage in wide areas, particularly many towns along the Pacific coast. So far, gravity change caused by such a great

The Effect of Hydraulic Fracturing on the 2021 Ms 6.0 Luxian Earthquake as Revealed by Deformation and Numerical Simulations

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This study investigates whether hydraulic fracturing contributed to the 2021 Ms 6.0 Luxian earthquake in the Sichuan Basin. Time‐series InSAR analysis of multi‐temporal Sentinel‐1 data reveals coseismic deformation associated with the 2021 Luxian earthquake and localized uplift near hydraulic fracturing platforms.

COSEISMIC SLIP DISTRIBUTION OF THE 2020 M_w 6.8 BENGKULU EARTHQUAKE DERIVED FROM THE GNSS OBSERVATIONS

Геодинамика и тектонофизика
On August 18, 2020, an MW 6.8 earthquake occurred ~130 km southwest of Bengkulu. In this study, we used the static GNSS data from continuously monitoring stations, surrounding the epicentre, to obtain the data from 10 days before to 10 days after the ...

Fluid‐Induced Magnetic Enhancement in Sandstone Friction Experiments: Implications for Coseismic Fault Temperature Estimates

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Constraining peak temperature during seismic slip is essential for quantifying earthquake energy budgets and fault weakening. Rock magnetic methods provide a sensitive means of estimating shear‐induced coseismic temperature rise; however, the role of fluids in friction‐induced magnetic alterations remains poorly constrained.

METHODOLOGY OF COSEISMIC DISPLACEMENTS COMBINATION OBTAINED BY DATA STEMMING FROM HETEROGENEOUS GEODETIC NETWORKS: ON THE EXAMPLE OF THE GREAT 2011 TOHOKU EARTHQUAKE, Mw 9.1

Геодинамика и тектонофизика
The strongest earthquakes with magnitudes Mw 8–9 generate coseismic displacements of the Earth’s crust, covering entire regions of the world. These displacements can be recorded using observations provided by the independent geodetic GNSS networks.

A probabilistic model for coseismic vertical displacement hazard in coastal settings

Geosphere
Characterizing coastal multi-hazards in tectonically active regions requires considering possible coseismic vertical deformation. Coseismic uplift or subsidence can cause near-instantaneous meter-scale relative sea level changes that can exacerbate or reverse the effects of ongoing global sea-level rise.

Significant afterslip contribution to postseismic deformation in Sado Island following the 2024 Noto Peninsula earthquake: insights from two dense GNSS observation networks

Earth, Planets and Space
This study investigated postseismic deformation resulting from the 2024 Noto Peninsula earthquake on January 1. Particular focus was placed on the displacement observed in Sado Island, which is located several tens of kilometers east of the eastern end ...
