The affected area is a remote and mountainous region of the north-western Qinghai province; the capital city of Xining is 12 hours away by road and many of the homes are built of wood and mud. Most of the locals are of Tibetan origin and rely on farming and livestock.
According to the Yushu Meteorological Bureau the majority of homes have collapsed and there are widespread power outages. The Red Cross has reported severe communication problems.
