Since 2000, there are 12 earthquakes that trigger more than 200000 landslides on the Tibetan Plateau (TP), causing disastrous impacts on human society and belonging to important driving forces in regional evolution. The rapid development of multiple advanced techniques and more relevant studies have contributed to much progress in understanding seismic landslides (SLs), but a synoptic survey that combines the insights of related studies to build a comprehensive understanding of SLs on the Tibetan Plateau is currently lacking. Here, we adopt recent landslides triggered by the 2005 Kashmir (Mw 7.6), 2008 Wenchuan (Mw 7.9), 2010 Yushu (Mw 6.9), 2013 Lushan (Mw 6.6), 2013 Minxian (Mw 5.5), 2015 Gorkha (Mw 7.8), 2017 Jiuzhaigou (Mw 6.5), 2017 Nyingchi (Mw 6.5), 2022 Maerkang (Mw 5.8) 2022 Lushan (Mw 5.8), 2022 Luding (Mw 6.6) and 2023 Jishishan (Mw 5.9) earthquakes on the Tibetan Plateau to illustrate the complex spatial distribution and control of SLs on the TP. The results show the seismic events are mainly concentrated in the eastern and southern margins of the TP, especially in the eastern margin of the Bayan Har fault block, as half of the total events are concentrated in the block; the SL distributions of thrust earthquakes follow the hanging wall effect, tectonic and geomorphic controls of SL distributions from different scales. As seismic magnitudes increase, the affected SL area, total SL number, total SL area and volume all follow an exponential growth. Compared to other earthquakes worldwide, the TP is more sensitive to SLs than other places, and slight seismic shaking (PGA < 0.1g) can trigger SLs; the landslide size distributions of the TP are similar to those of other earthquakes worldwide. SLs on the TP need longer recovery periods, approximately 3~10 times those of coastal earthquakes
