Erosion Associated with Seismically-Induced Landslides in the Middle Longmen Shan Region, Eastern Tibetan Plateau, China
The 2008 Wenchuan earthquake and associated co-seismic landslide was the most recent expression of the rapid deformation and erosion occurring in the eastern Tibetan Plateau. The erosion associated with co-seismic landslides balances the long-term tectonic uplift in the topographic evolution of the region; however, the quantitative relationship between earthquakes, uplift, and erosion is still ...
متن کاملPaleoglaciation of Shaluli Shan, southeastern Tibetan Plateau
Reconstructing the paleoglaciation of the Tibetan Plateau is critical to understanding linkages between regional climate changes and global climate changes, and herewe focus on the glacial history of the Shaluli Shan, an area of the southeastern Tibetan Plateau that receives much of its precipitation from monsoon flow. Based on field investigation, geomorphological mapping, and 10Be exposure da...
متن کاملTwo phases of Mesozoic north-south extension in the eastern Altyn Tagh range, northern Tibetan Plateau
[1] The >300-km long, east striking Lapeiquan fault lies in the eastern Altyn Tagh range along the northern margin of the Tibetan Plateau and was interpreted as a north dipping thrust in early studies. However, our mapping shows that the fault is a south dipping normal fault juxtaposing Archean-Proterozoic gneisses beneath an early Paleozoic volcanic and sedimentary sequence. Its dip angle vari...
متن کاملA special issue on the great 12 May 2008 Wenchuan earthquake (Mw7.9): Observations and unanswered questions
The 12 May 2008 Wenchuan earthquake (Mw 7.9) ruptured the active Longmen Shan thrust belt bounding the eastern margin of the Tibetan plateau against the Sichuan basin (Fig. 1) (Burchfiel et al., 2008). Initial observations of this devastating earthquake were reported in several short papers focusing on coseismic slip and earthquake-fault geometry (e.g., Wang et al., 2008; Xu et al., 2009; Lin e...
متن کاملDeep slip rates along the Longmen Shan fault zone estimated from repeating microearthquakes
[1] We investigated deep slip rates along the Longmen Shan fault zone where the devastating 2008 M7.9 Wenchuan earthquake occurred using repeating earthquake data recorded by two digital seismic networks near the fault. Using cross‐correlation analysis of waveform data, we identified a total of 231 doublets and 224 multiplets that have highly similar waveforms. Most of these sequences are aperi...
