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 ...

Coseismic dislocation modeling by physical experiments

, 2013
Detecting coseismic surface deformation provides useful information about geometry and kinematic of the seismo- genic fault activated during an earthquake. Recent advances in inversion of geodetic data (e.g.

Synthetic Hybrid Broadband Seismograms Based on InSAR Coseismic Displacements

, 2014
Conventional acceleration records do not properly account for the observed coseismic ground displacements, thus leading to an inaccurate definition of the seismic demand needed for the design of flexible (long period) structures.

Re-examination of TEC anomalies in the ionosphere before large earthquakes

Earth, Planets and Space
We examine GNSS-derived total electron content (TEC) variations preceding four large megathrust earthquakes: the 2011 Tohoku–Oki (Mw 9.0), 2014 Iquique (Mw 8.2), 2015 Illapel (Mw 8.3), and 2009 Dusky Sound (Mw 7.8) events.

A New Analytical Simulation Code of Acoustic-Gravity Waves of Seismic Origin and Rapid Co-Seismic Thermospheric Disturbance Energetics

Atmosphere
A recent study the detection of coseismic ionospheric disturbances or ionoquakes less than 400 s from the earthquake’s onset. The study also associates these rapid ionoquakes with the seismo-atmosphere–ionosphere (SAI) coupling mechanism energized by ...

Response of coseismic landslide susceptibility to the temporal scales and interactions of deformation and rainfall

Geomatics, Natural Hazards & Risk
This study examines how the time scales of rainfall and deformation and their interaction affect coseismic landslide susceptibility assessment. Based on 5007 landslides triggered by the 5 September 2022, Luding earthquake, we integrated 18 causative ...

Dynamics, radiation and overall energy budget of earthquake rupture with coseismic off‐fault damage

, 2019
International audienceEarthquake ruptures dynamically activate coseismic off-fault damage around fault cores. Systematic field observation efforts have shown the distribution of off-fault damage around main faults, while numerical modeling using elastic ...

Coseismic and Postseismic Deformations of the 2023 Turkey Earthquake Doublet

On 6 February 2023, an earthquake doublet of Mw 7.8 and Mw 7.5 occurred in southeastern Turkey and caused surface ruptures over 350 km for the eastern Anatolian fault (EAF) and 150 km for the Surgu fault (SF), respectively. Over 3700 Mw > 3.0 aftershocks
