Holocene Activity of the Wudaoliang–Changshagongma Fault of the Eastern Tibetan Plateau

The Wudaoliang–Changshagongma fault is one of the NW-trending faults located within southern Bayan Har Block Tibetan Plateau in China. In this paper, we used high-resolution imagery and digital elevation model data to study geomorphological geological characteristics fault. Furthermore, result also determined trace estimated average horizontal slip rate since late Quaternary have been 2.6 ± 0.6 mm/a. This approximately equivalent that Awancang, Madoi–Garde, Dari faults, which are block. rates these obtained by remote sensing methods consistent with GPS observations. It indicates tectonic deformation block continuous diffuse. Using trenching results sedimentary radiocarbon dating, identified four paleoearthquake events occurred at 42,378–32,975, 33,935–20,663, 5052–4862, after 673–628 cal BP, respectively. recurrence intervals large earthquakes on much longer than those boundary smaller, indicating play a regulatory role Block.
