Present-day distribution of deformation around the southern Tibetan Plateau revealed by geodetic and seismic observations

Late Quaternary Extension Rates Across the Northern Half of the Yadong‐Gulu Rift: Implication for East‐West Extension in Southern Tibet

“…Later GPS studies (Gan et al, 2007) found a 2.0 ± 0.6 mm/yr extension rate across the YGR (#4), roughly consistent with that inferred by Armijo et al (1986) (1.4 ± 0.8 mm/yr) and with our own rate south of the Gulu bend (1.3 ± 0.3 mm/yr), as well as a left‐lateral strike‐slip rate of 0.7 ± 1.1 mm/yr, also in keeping with our left‐lateral slip rate near Damxung (0.9 ± 0.3 mm/yr). Finally, in a recent 3‐D microblock kinematic model, Tian et al (2019) used geodetic and seismic observations to infer an extension rate of 5.6 ± 0.8 mm/yr in the northern YGR (#5 in Figure 19a and Table 3), which would be consistent with our faster local result. However, their model also yields a right‐lateral slip‐rate component of 1.4 ± 0.9 mm/yr in the same area, while the NE‐trending active transfer segment between Yangbajing and Gulu unquestionably entails a significant component of left‐lateral faulting.…”

Holocene Slip Rate Along the Beng Co Fault and Dextral Strike‐Slip Extrusion of Central Eastern Tibet

“…The overall, combined, Mid‐to‐Early Holocene (3–9 ka), slip‐rate (4.2–5.4 mm/yr) we obtain along the eastern stretch of the fault that ruptured during the 1951, Mw 7.7 earthquake is generally consistent with the majority of the rates derived from GPS and InSAR data along that stretch in the last decade or so (e.g., Garthwaite et al., 2013; Y. S. Li et al., 2020; Tang et al., 2010; L. Zhang et al., 2021; Figure 11b; Table 4). Similarly, rates inferred from broad‐scale block modeling along the entire BCF (Meade, 2007; Tian et al., 2019) fall around values of ∼5 mm/yr. Finally, one of the much longer‐term rates deduced from propagating along KJfz a large, inferred, Miocene offset ∼65 km from Taylor et al.…”

“…Zhang et al, 2021;Figure 11b; Table 4). Similarly, rates inferred from broad-scale block modeling along the entire BCF (Meade, 2007;Tian et al, 2019) fall around values of ∼5 mm/ yr. Finally, one of the much longer-term rates deduced from propagating along KJfz a large, inferred, Miocene offset ∼65 km from Taylor et al (2003) across the Karakoram fault (11b in Table 4 and Figure 11b) also partly overlaps with the ∼5 mm/yr rate that fits with most of the other local data plotted in Figure 11b.…”

“…Based on dated fan and moraine offsets, dextral rate values along the northern (Chevalier et al, 2011) and central/southern (Chevalier, 2018;Chevalier et al, 2005Chevalier et al, , 2012Chevalier et al, , 2016 Karakoram fault vary between ∼5 and ∼12 mm/yr. Along the western KJfz faults (western Bangong suture), a rate based on GPS block modeling has been inferred to be on order of ∼9 mm/yr (Tian et al, 2019). Holocene rates along the Gyaring Co fault (GCF) range between 1 and 5 mm/yr (Shi et al, 2014;D.…”

Frictional Properties and Rheological Structure at the Ecuadorian Subduction Zone Revealed by the Postseismic Deformation Due To the 2016 Mw 7.8 Pedernales (Ecuador) Earthquake

“…Different processing software, parameters or reference frame realizations can produce different coordinates for the same position (Bettinelli et al, 2006;Tian et al, 2019Tian et al, , 2020. Therefore, we first inspected the consistency in the three sets of data: the NGL and our data processed by the GIPSY, and the coastal sites processed by the GAMIT/GLOBK from Rolandone et al (2018), by comparing the original time series and derived displacements at some common sites.…”
