“…Our estimate of motion across the Tanlu fault supports a relatively long seismic interval of ∼10 ka, comparable to those inferred from recent paleoseismic research on this fault (K. Li et al., 2019; Shu et al., 2020) and other slow‐slip faults (Guo et al., 2017) in the NCC. Our analysis suggests that the faults in the NCC even with very slow motions may still have the potential to produce strong earthquakes since the Holocene.…”

“…(2019). Our inference of the recurrence interval for the Tanlu fault is also close to that across the Yilan‐Yitong fault in northeast China (Shu et al., 2020) and similar to those along other slow‐slip faults in this region (Guo et al., 2011, 2017).…”

“…Li et al, 2019), the strike-slip motion of ∼0.9 mm/ yr derived in this study also supports a long interval of ∼10 ka, consistent with recent paleoseismic research of K. Li et al (2019). Our inference of the recurrence interval for the Tanlu fault is also close to that across the Yilan-Yitong fault in northeast China (Shu et al, 2020) and similar to those along other slow-slip faults in this region (Guo et al, 2011(Guo et al, , 2017.…”

“…Note that, as mentioned, previous estimates of the recurrence interval of large earthquakes along the Tanlu fault remain debated. For instance, earlier geological studies have proposed that this fault is characterized by a mean seismic interval of ∼3,500 years (Jiang et al., 2017; J. Li et al., 1994; Lin & Gao, 1987); whereas recent paleoseismic research suggested that its seismic interval may be much longer, reaching at least ∼10 ka (Cao et al., 2018; K. Li et al., 2019; Shu et al., 2020). These discrepancies might arise from the large uncertainties in dating of paleoseismic events, causing disparity in Holocene slip estimates: the slower value of ∼0.7 mm/yr (K. Li et al., 2019) versus the faster value of ∼2.6 mm/yr (Jiang et al., 2017).…”

North China, commonly known as the North China Craton (NCC), is an important tectonic element in eastern China (R. Zhu et al., 2011Zhu et al., , 2012. This region is characterized by complex tectonic setting, intense seismic activity and dense population (Deng et al., 2003). Unlike the Tibetan Plateau situated in western China, where numerous active faults exhibit fast motions and significant deformation, the faults in the NCC generally have slow motions (Deng et al., 2002). However, numerous strong earthquakes have occurred in this region during the past hundred years, including the 1976 M 7.8 Tangshan event that has caused huge casualties (P. Zhang et al., 2013). In this context, quantifying the faulting kinematics and slip partitioning holds great significance for seismic risk assessments.Over the past decades, numerous studies have been conducted on the tectonic processes and deformation mechanisms in the NCC. For example, it has been suggested that most deformation features in the NCC can be explained as the combined effects of the India-Eurasia collision and Pacific subduction (Ye et al., 1987;Yin, 2010); however, the relative significance involving with these two factors remains unclear. Moreover, several studies have proposed that the late Cenozoic tectonics in this region is mainly characterized by widespread rifts that have caused intensive extensional deformation (Y. Q. Zhang et al., 1998
