At least 118 people were killed and over 500 others injured when a powerful 6.2-magnitude earthquake struck a remote mountainous region in northwest China just before midnight, the local earthquake relief headquarters said on Tuesday.
According to the China Earthquake Networks Centre, the shallow quake jolted Gansu and Qinghai provinces at 11:59 p.m. on Monday, with a focal depth of 10 kilometres. The epicentre of the earthquake Liugou township is about 8 kilometres from the county seat of Jishishan Bao'an, Dongxiang, Sala autonomous county in Linxia Hui autonomous prefecture in Gansu.
Experts say shallow quakes cause heavy damage to infrastructure.
Qinghai province is adjacent to the Tibet Himalayan region which is prone to frequent earthquakes due to shifting of continental plates.
A second quake struck the neighbouring Xinjiang Uygur Autonomous Region hours later on Tuesday.
