Located in the western part of Central Tibet (sometimes referred to as "western Tibet"), it is the birthplace of the Tsangpo River (Brahmaputra). The county seat is at Labrang, which is also called the Drongpa Town (Zhongba Xian). Geography Drongpa County is the largest county in the Shigatse Prefecture by geographical area. It has a population of approximately 18,000 and covers 43,594 square kilometers. It is prone to earthquakes and suffered a large one, 6.8 on the Richter scale, on 30 August 2008.
