英文摘要	Under the climate warming, the ice avalanches (IAs) and glacier lake outburst floods (GLOFs) will continue or even intensify in the future. In order to find out the number, spatial distribution, and characteristics of hidden dangers of IA and GLOF-prone lakes on the Tibetan Plateau (TP), the first inventory is presented. (1) The study has identified and analyzed 581 IAs and 369 GLOFs on the TP. IAs and GLOFs are widely distributed in the Tibet Autonomous Region (TAR), concentrating in the Yarlung Zangbo River basin and the Nyainqntanglha and Himalaya Mountain range. (2) Most of the IAs have an area of 0.1 similar to 1 km(2). The IAs occur on vulnerable slopes ranging from 35 to 45 degrees, with an elevation between 4500 and 5500 m and a north-friendly aspect. (3) Most of the GLOFs with a lake area of 0.1 similar to 0.3 km(2) and a north-facing outburst direction are developed in an elevation range from 4500 to 5500 m. There are about half of the GLOF-prone lakes to be close to the front edge of the mother glaciers. (4) The front elevation of IAs changes regularly with the eastern Himalayan syntaxis region as the boundary. It generally increased from west to east on the west side, while a V-shaped trend first decreased and then increased, and decreased from south to north on the east side. (5) The IAs and GLOFs are mainly distributed in the southern and northwestern TP with clustering characters due to the topographical and climatic settings.
