Besides, a total of 117 have sustained injuries, state- run Xinhua news agency reported.
The 7.9 Richter Scale temblor that struck Nepal on Saturday also affected parts of Tibet. The two border ports to Nepal were seriously affected. The earthquake also affected the south-western part of Tibet, especially Xigaze City.
The city has 18 counties and prefectures, and a population of more than 700,000.
The earthquake tragedy in Nepal, worst in over 80 years in the Himalayan nation, has so far left over 4,000 dead, including five Indians, and about 7,000 others injured.
The number of casualties is likely to increase as access and communication returns to normal, a spokesperson of the headquarters said.
"We worry most about Zham Town. Rescue work there is particularly difficult because the road to the town is blocked," Mayor of Xigaze City Zhang Hongbo said.
The town is in short supply of food and bottled water. Food stocks will last likely only for three days.
A 37-km highway linking Nyalam County with Zham has been blocked by multiple landslides.
Rescuers are still working to clear an important tunnel that winds through high mountains.
