The Tibetan Plateau is an active seismic region due to the collision between Indian and Eurasian plates. We have set up a new seismic network in the heart of the Tibetan Plateau, in the Lhasa region, to detect seismic activities. The measured data show that Lhasa is a seismically active region where at least 716 earthquakes were detected and a total of 218 events of magnitude greater than 2.0 occurred in the period between January 2004 and July 2006. Out of them, 11 earthquakes had a magnitude greater than 5.0. A high seismic activity was observed along the Dangshung fault zone.

<p>     The Jinsha river fault zone in the eastern margin of the Tibetan Plateau is an old suture structure after the shutting of the proto-Tethys and a large scale ultra-lithosphere fault zone consisted of  5 to 6 fault branches with a width of 50km, have a long  geological evolution history. Since late Quatery, this fault zone is mainly dominated by dextral strike slip with partial thrusting component, absorbing  partial energy of the extrusion movement of  Tibetan Plateau. Along the fault zone, lower terraces of Jinsha river at Muronglou, Buzhong, Langzhong, Guxue, etc. were displaced, indicating the fault zone is active in late Quaternary, with an average rate of 3.5～4.3mm/ /yr. horizontally and 0.9-1.1mm/yr. vertically respectively in Holocene. Influenced by the intense fault activity of Jinsha river fault zone, this region is characterized by fractured rocks, strongly weathered surfaces.</p><p>      The Jinsha river, the upstream of the Yangtze river, parallel to Jinshajiang fault zone, flows from north to south, forming deep river valley and huge terrain elevation difference. Numerous huge landslides have developed along the river, for example, there are 23 giant avalanches in the 38 km long reach from Narong to Rongxue, with general volumes of 10~70 million m<sup>3</sup> and even up to several hundreds million m<sup>3</sup>. Moreover, the landslides produce many loose clastic fragments which detonate many debris flows and river blocking. The latest disaster event is the Baige barrier lake in 2018 caused by landslide, with a water storage capacity of 524 million m<sup>3</sup>, causing tens of billions of yuan of economic losses. These landslides are distributed along the fault and its two sides, suggesting that these huge avalanches are closely related to the intense activity of the fault zone and special topography.</p><p>Keywords: Huge landslide, Jinsha River, Jinsha River Fault Zone, late Quatery activity</p>

Abstract The Tibetan Plateau and surrounding mountain regions covers 5 million square kilometres—nearly half the China's landmass—with an average elevation of over 4000 metres. It's often regarded as the Third Pole because it has the largest stock of ice outside the Arctic and the Antarctic. Tibetan Plateau research is one of China's Strategic Pioneering Programmes that was launched in 2012 with a budget of 300 million yuan (US $47 million) over 5 years and is led by Chinese Academy of Sciences (CAS)’ Institute of Tibetan Plateau Research (ITP) in Beijing. In January 2014, CAS set up the Centre for Excellence in Tibetan Plateau Earth Sciences, headquartered in ITP, aiming at providing long-term support for this area of research and raising academic standards. NSR recently talked to glaciologist Tandong Yao and geologist Weiming Fan—ITP's director and deputy director, respectively—about why Tibetan Plateau research is important, what it is like to work there, how the region is faring in face of climate change and why international collaboration is important.
