Possible seismo-ionospheric precursor of the 12 February 2014 Yutian earthquake in China

Journal of Earth System Science, 2019
On 12 February 2014, a major earthquake occurred near the Yutian County, China. In this paper, the ionospheric variations around the time of this earthquake were analysed on the basis of the global positioning system vertical total electron contents (VTEC) and computerised ionospheric tomography (CIT) electron density distributions.

Stress transfer along the western boundary of the Bayan Har Block on the Tibet Plateau from the 2008 to 2020 Yutian earthquake sequence in China

Geophysical Research Letters, 2021
Eight Ml≥7.0 earthquakes have occurred around the Bayan Har block, NW Tibet, China, since 2000, resulting in a large number of casualties and countless economic loss. Near the western boundary of the Bayan Har block, four Ml≥6.0 Yutian earthquakes have occurred from 2008 to 2020.

Geomorphology and Paleoseismology of the Weinan Fault, Shaanxi, Central China, and the Source of the 1556 Huaxian Earthquake

Journal of Geophysical Research: Solid Earth, Volume 125, Issue 12, December 2020., 2020
The 1556 CE Huaxian earthquake resulted in an estimated 830,000 deaths and caused widespread devastation in the Weihe Basin, China. Seismic intensities from historical accounts yield, via magnitude‐intensity relations, a commonly quoted magnitude of 8¼ to 8½.

Failure Mechanism and Mitigation Measures of the G1002 Electricity Pylon Landslide at the Jinping I Hydropower Station

Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020
On August 29 and 30, 2012, local extreme rainfalls struck the construction area of the Jinping I Hydropower Station, Xichang, China, and triggered many geohazards. The upper region of the left valley slope 200 m downstream of the dam failed and slid, exposing the D‐pile of the G1002 electricity pylon and threatening the entire power transmission line ...

Differential motions of the Gozha Co Fault (Xizang) before and after the 2008 Yutian earthquake revealed by ENVISAT-1 ASAR

地球与行星物理论评
Shallow fault creep is a relatively rare phenomenon, often indicating a lower seismic risk (less strain accumulation). Previous studies have revealed shallow creep on the Gozha Co Fault in the western Qinghai-Xizang Plateau using Sentinel-1 and ALOS-2 ...

Analysis of ionospheric VTEC disturbances before and after the Yutian Ms7.3 earthquake in the Xinjiang Uygur Autonomous Region

Geodesy and Geodynamics, 2014
An earthquake with a magnitude of Ms7.3 hit Yutian in the Xinjiang Uygur Autonomous Region on February 14, 2014. This research investigates the interference phenomena in solar activities and geomagnetics, and adopts the quartile method to analyze the ...

Source Model of the 2014 Mw 6.9 Yutian Earthquake at the Southwestern End of the Altyn Tagh Fault in Tibet Estimated from Satellite Images [PDF]

Seismological Research Letters, 2020
AbstractMultiple fault segments ruptured during the 2014 Yutian earthquake, but the detailed source parameters and the mechanism of rupture complexity remain poorly understood. Here, we use high-resolution TanDEM-X satellite data and Satellite Pour l’Observation de la Terre-6/7 images to map the coseismic ground deformation field of the event.

Preseismic deformation associated with the 2014 Ms7. 3 Yutian earthquake derived from GPS data

Geodesy and Geodynamics, 2014
Based on analysis of the GPS data during 1999–2007, 2009–2011, and 2011–2013 mainly from the Crustal Motion Obseration Network of China, we obtained the GPS horizontal velocity field, the GPS strain rate field, and the profiles across the southwestern ...

Numerical investigation of the correlations of hydraulic and elastic characteristics in diverse carbonate rock types

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 266-276, March 2026.
We use the linear Boolean model and the discrete Fourier transformation approach to generate various carbonate rocks. The lattice Boltzmann method and the finite element method are applied to calculate permeability and elastic wave velocity, respectively.

Regulation of Particulate Organic Carbon by Cascade Mega‐Reservoirs in the Changjiang Basin: Enhanced Sequestration and Altered Downstream Composition

Global Biogeochemical Cycles, Volume 39, Issue 8, August 2025.
Abstract Artificial reservoirs significantly alter the natural transport of suspended particulate matter (SPM) from rivers to oceans, thereby reshaping the global carbon cycle through changes in particulate organic carbon (POC) dynamics over decadal to millennial timescales.
