Deformation Pattern Modifications Induced by 2021 Brentonico Earthquake: Insights from EGMS Ortho Products [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Post-seismic deformation reflects the crustal adjustment to stress perturbations induced by earthquakes and may lead to modifications of ongoing deformation patterns.

Geodetic observations of post-seismic transients in the context of the earthquake deformation cycle

Comptes Rendus. Géoscience, 2006
Satellite geodetic techniques that can measure displacements with millimeter-level accuracy reveal transient signals in the deformation fields produced by both moderate and large earthquakes. These post-seismic signals exhibit characteristic time scales ranging from weeks to decades and distance scales from hundreds of meters to hundreds of kilometers.

Rheology of the Zagros Lithosphere from Post-Seismic Deformation of the 2017 Mw7.3 Kermanshah, Iraq, Earthquake [PDF]

Remote Sensing, 2020
We use 2018–2020 Sentinel-1 InSAR time series data to study post-seismic deformation processes following the 2017 Mw 7.3 Kermanshah, Iraq earthquake. We remove displacements caused by two large aftershock sequences from the displacement field. We find that for a six month period the response is dominated by afterslip along the up-dip extension of the ...

The development of magmatism along the Cameroon Volcanic Line: evidence from seismicity and seismic anisotropy [PDF]

, 2014
The Cameroon Volcanic Line (CVL) straddles the continent-ocean boundary in West Africa but exhibits no clear age progression. This renders it difficult to explain by traditional plume/plate motion hypotheses; thus, there remains no consensus on the ...

Extraction and identification of transient deformation after the Ludian earthquake

Geodesy and Geodynamics
This study investigates the transient deformation signals associated with the Ludian M6.8 earthquake, which occurred on June 22, 2014, in southwestern China, using Global Navigation Satellite System (GNSS) data. Within the framework of the Kalman filter,

A New Method to Evaluate the Post-Earthquake Performance and Safety of Reinforced Concrete Structural Frame Systems

Infrastructures, 2020
This study examines the relation between maximum seismic displacements and residual displacements for reinforced concrete building structures. In order to achieve a reliable relationship between these critical structural parameters for the seismic ...

GEODETIC EVIDENCE FOR POST-SEISMIC DEFORMATIONS FOLLOWING THE 2014 NORTH AEGEAN MW 6.9 EARTHQUAKE

Geodesy and cartography, 2023
The 2014 North Aegean Sea earthquake was a strong (Mw 6.9) event that caused significant crustal deformations. In the present study we investigate the long-term impact of the earthquake on the kinematics of the North Aegean Trough (NAT). For this purpose, we analyzed GPS observations collected from May 2010 to April 2022 at five permanent GPS reference

Co‐ and Post‐Seismic Mechanisms of the 2020 Mw 6.3 Yutian Earthquake and Local Stress Evolution

Earth and Space Science, 2023
The Mw 6.3 Yutian earthquake, occurred in northwestern Tibet on 25 June 2020, is one of the major events sequentially occurring in the region following the 2008 Mw 7.2, 2012 Mw 6.2, and 2014 Mw 6.9 earthquakes, and is of great significance for studying ...

Coseismic and early post-seismic deformations due to the 2019 earthquake sequence in Ridgecrest, California

Geophysical Journal International, 2022
SUMMARYThe 2019 Ridgecrest earthquake sequence in the Mojave Desert that ruptured a complex orthogonal conjugate fault system offers a rare opportunity to probe the mechanics of the intraplate lithosphere of the central eastern California shear zone (ECSZ).
