A Continuous 13.3-Ka Paleoseismic Record Constrains Major Earthquake Recurrence in the Longmen Shan Collision Zone

Thrust collision zones with low slip rates along the plate boundary are significant areas of stress accumulation and prone to develop more destructive earthquakes longer recurrence intervals. Such regions often classified as seismic risk if they lack continuous records large earthquakes, such eastern Tibetan Plateau before 2008 M w 7.9 Wenchuan earthquake. Here, we provide a record in Longmen Shan thrust fault zone spanning 13,000 years based on detailed investigation soft-sediment deformation structures seismites Lixian lacustrine sequence. The time ( ? 8.1) is 1,200 years, which significantly shorter than previous estimate 2,000–6,000 years. Maoxian-Wenchuan main that triggered sediments. In addition, earthquake warm period frequent cold period, should arouse our attention for study tectonically active regions.
