Slip Deficit Rate and Seismic Potential on Crustal Faults in Tibet
Geophysical Research Letters, Volume 52, Issue 1, 16 January 2025.Abstract Quantifying slip deficit rates on active faults in Tibet is essential for understanding fault kinematics and assessing seismic hazards, but has not been fully characterized, particularly on secondary faults. In this study, we integrate an updated interseismic Global Navigation Satellite Systems velocity field from 4,458 stations across ...

Earthquakes Have Accelerated the Carbon Dioxide Emission Rate of Soils on the Qinghai‐Tibet Plateau
Global Change Biology, Volume 31, Issue 1, January 2025.Earthquakes on the Qinghai‐Tibet Plateau not only damage infrastructure but also increase carbon dioxide emissions. This study found that fissures caused by these earthquakes expose frozen soils to the air, leading to an increase in soil carbon emission rates by 0.71 g CO2 m−2·a−1.

Frontiers in Earth ScienceThe 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.

Coseismic Shallow Slip Deficit Accounted for by Diffuse Off‐Fault Deformation
Geophysical Research Letters, Volume 51, Issue 24, 28 December 2024.Abstract Earthquake ruptures produce fault slip and kilometer‐wide diffuse deformation of the host rocks. However, the origin of the diffuse deformation and its role in the rupture process are debated. We produce a refined slip model for the 2019 Ridgecrest, California, earthquakes, and analyze the relations between down‐dip rupture process, and ...

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.

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 ...
