Repurposing deep closed mines as seismic forecasting research platforms [PDF]

Seismic forecasting remains constrained by surface noise and low spatial resolution, limiting reproducible predictions. Although deep borehole stations and underground laboratories improve conditions, they face high costs, sparse coverage, and narrow ...

Strain Partitioning, Interseismic Coupling, and Shallow Creep Along the Ganzi‐Yushu Fault From Sentinel‐1 InSAR Data

Geophysical Research Letters, Volume 51, Issue 21, 16 November 2024.
Abstract The Ganzi‐Yushu fault (GYF) is one of the most seismically active fault systems in eastern Tibet, having experienced five M > 7.0 earthquakes over the past 300 years. Here, we use Sentinel‐1 InSAR data spanning from 2014 to 2023 to derive the interseismic velocity fields along the GYF.

Characteristics of regional tectonic stress field in Wenchuan area and the effect of Wenchuan MS8.0 earthquake on surrounding major fault surfaces

地震科学进展, 2022
To analyze the influence of the 2008 Wenchuan MS8.0 earthquake on later earthquakes and the characteristics of the tectonic stress field in the seismogenic region, we first used 1660 source mechanism solutions of the Wenchuan earthquake and its ...

The earthquake-controlling process of continental collision-extrusion active tectonic system around the Qinghai-Tibet Plateau: A case study of strong earthquakes since 1990 [PDF]

Objective  The Qinghai-Tibet Plateau is one of the most seismically active regions along the Mediterranean-Himalayan seismic belt. Understanding the earthquake-controlling effect of the active tectonic system in this region is crucial for analyzing ...

Strain Partitioning in the Southeastern Tibetan Plateau From Kinematic Modeling of High‐Resolution Sentinel‐1 InSAR and GNSS

Geophysical Research Letters, Volume 51, Issue 19, 16 October 2024.
Abstract Fault slip rates estimated from geodetic data are being integrated into seismic hazard models. The standard approach requires modeling velocities and relative (micro‐)plate motions, which is challenging for fault‐based models. We present a new approach to directly invert strain rates to solve for slip rates and distributed strain ...

Mechanism of abrupt supershear rupture for the 2021 Maduo earthquake (Mw=7.4) in the northern Tibetan Plateau

Frontiers in Earth Science
The 2021 Maduo earthquake (Mw = 7.4) is the first sudden and abrupt supershear rupture ever documented in the history of seismology, in which subshear rupture changed to supershear within a short time and short distance.

Refining 3D Displacement Fields and Coseismic Slip Models of the 2023 Kahramanmaraş Earthquakes Using Subswath and Burst Overlap Interferometry (SBOI) [PDF]

The 6 February 2023 Kahramanmaraş Earthquakes caused extensive deformation along the East Anatolian Fault Zone, producing significant north-south displacements. Standard Interferometric Synthetic Aperture Radar (InSAR) methods face significant challenges

Crustal displacement accompanying earthquakes activities in Egypt [PDF]

In Egypt, there were many earthquakes activities in seismo-tectonic regions. In the last century most of earthquakes concentrated at Gulf of Suez and Gulf of Aqqaba. Also, Egypt affected by large earthquakes in the northern Mediterranean Sea.

Space Geodetic Insights to the Dramatic Stress Rotation Induced by the February 2023 Turkey‐Syria Earthquake Doublet

Geophysical Research Letters, Volume 51, Issue 6, 28 March 2024.
Abstract The February 2023 Turkey‐Syria Earthquake doublet ruptured multiple segments of the East Anatolian Fault (EAF) Zone. Dominating seismicity focal mechanism shifted dramatically from strike‐slip to normal‐faulting after the doublet. To better understand this shift, here we derived a comprehensive 3D co‐seismic displacement field and performed ...
