Effects of crustal layering on source parameter inversion from coseismic geodetic data

, 2004
We study the effect of a superficial layer overlying a half-space on the surface displacements caused by uniformslipping of a dip-slip normal rectangular fault.We compute static coseismic displacements using a 3-D analytical code for different ...

Interseismic, Coseismic, and Early Postseismic Slip Associated With the 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Unraveling the surface deformation and fault kinematics during the seismic cycle is crucial for understanding earthquake physics. Herein, we use geodetic and seismic observations to quantify the interseismic coupling, coseismic rupture, and postseismic afterslip associated with the 2025 Mw 8.8 Kamchatka earthquake.

Use of the ESI-2007 scale to evaluate the 2003 Boumerdès earthquake (North Algeria)

Annals of Geophysics, 2016
In this study, we applied the environmental seismic intensity (ESI-2007) scale to a major recent Algerian earthquake. The ESI-2007 scale is an effective tool to assess the seismic hazard and has been applied to onshore earthquakes.

Crustal deformation in extensional regimes: Iceland, Nevada and SW Turkey [PDF]

, 1996
In 1991 a 23-point, 30 x 25 km, GPS geodetic network was established in the Hengill ridge-ridge-transform triple junction, SW Iceland. The GPS data were processed using the Bernese V3.2 software.

Multi‐Stage Shallow Rupture and Pre‐Event Shallow Deformation During the 2025 Mw 5.9 Asadabad Earthquake (Afghanistan)

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The 31 August 2025 Mw 5.9 Asadabad earthquake in eastern Afghanistan caused severe damage despite its moderate magnitude, raising questions about rupture processes and seismic hazard in the southern Hindu Kush. Using Sentinel‐1 InSAR and teleseismic waveform modeling, we reveal a complex, multi‐stage shallow (4–5 km) rupture involving the ...

The depth of pseudotachylyte formation from detailed thermochronology and constraints on coseismic stress drop variability [PDF]

, 2012
Pseudotachylytes are accepted as recording paleo-seismicity in the rock record. However, the interpretation of the mechanics of faulting based on pseudotachylyte generation is often hindered because the depth at which they form is poorly constrained ...

Tectonics and Sliver Motion in Costa Rica: Strain Partitioning Constrained by GNSS Velocities Data

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The tectonic deformation of Costa Rica is controlled by the subduction of the Cocos Plate beneath the Caribbean Plate and the Panama microplate along the Middle America Trench, with oblique convergence in northern Costa Rica to 2024 from 154 permanent stations distributed across Costa Rica to derive for the first time spatially continuous ...

Fast report: the 2025 M6.4 Dapu earthquake: preliminary field observation and surface deformation analysis

Terrestrial, Atmospheric and Oceanic Sciences
The 2025 M6.4 Dapu earthquake offers a crucial opportunity to investigate coseismic deformation and fault behavior in southwestern Taiwan. Despite the absence of surface rupture, remote sensing and geodetic analyses detected significant ground ...
