Frontiers in Earth Science, 2022 By using GPS-derived velocities of 2015–2021 and a negative dislocation program, we inverted the locking degree and slip rate deficit in the Qilian–Haiyuan fault zone, and combined with the distribution of small earthquakes in the fault, we studied the ...

Geophysical Research Letters, Volume 49, Issue 24, 28 December 2022., 2022 Abstract We use Sentinel‐1 Interferometric Synthetic Aperture Radar observations to derive the first complete map of slip‐rate distribution at km‐scale along the 1,000‐km‐long Haiyuan fault system, and further to analyze its earthquake potential. Rate distribution reveals four highly locked asperities (slip rate <1 mm/yr) and three creeping regions ...

Earth and Space Science, Volume 9, Issue 11, November 2022., 2022 Abstract The 2022 Mw 6.6 Menyuan earthquake occurred in the Qilian‐Haiyuan fault system in northeastern Tibet. To investigate the mechanism behind the 2022 Menyuan earthquake and the seismic hazards (SHs) of the Tianzhu seismic gap, the spatiotemporal stress variations on the Qilian‐Haiyuan fault zone were assessed before and after 2022 by modeling the

Large‐Scale Interseismic Strain Mapping of the NE Tibetan Plateau From Sentinel‐1 Interferometry
Journal of Geophysical Research: Solid Earth, Volume 127, Issue 6, June 2022., 2022 Abstract The launches of the Sentinel‐1 synthetic aperture radar satellites in 2014 and 2016 started a new era of high‐resolution velocity and strain rate mapping for the continents. However, multiple challenges exist in tying independently processed velocity data sets to a common reference frame and producing high‐resolution strain rate fields.

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022 Compared with strong earthquakes (Ms ≥ 6.0), light‐moderate earthquakes (Ms 4–5.9) occurred more frequently and distributed more widely, and rich ground motions have been collected around world. It provides a solid data base for the investigation on the ground motion and regional site characteristics which are closely related to seismic geological ...

Journal of Geophysical Research: Solid Earth, Volume 126, Issue 12, December 2021., 2021 Abstract Earthquake slip distributions help constrain rupture behavior and return times. Here, by combining 0.5‐m‐resolution image and topographic data interpretation with fieldwork, we quantify the co‐seismic throw distribution and rupture geometry of the 1609 Hongyazi earthquake along the Qilian Shan Fodongmiao fontal thrust (NE Tibet).
