In China, about 400 people have died and 10,000 others injured after a 7.1-magnitude earthquake hit northwest China's Qinghai Province early today. The powerful tremor struck remote Yushu county, 800 kilometre south-west of the provincial capital Xining at 0749 a.m. local, at a shallow depth of 10km. The strong quake and a string of aftershocks, with the biggest one being 6.3 magnitude, have toppled houses, temples, gas stations and electric poles, triggered landslides, damaged roads, cut power supplies and disrupted telecommunications. A reservoir was also cracked, where workers were trying to prevent the outflow of water. Police said hundreds of survivors had already been pulled out from the rubble. Many students are buried under the debris of a vocational school, which collapsed due to the quake. The death toll has been rising throughout the day as many people are still buried under the debris of collapsed houses in the Gyegu Town near the epicenter in the Tibetan Autonomous Prefecture of Yushu in southern Qinghai. Gyegu, also known as Jiegu, is the seat of the Yushu prefecture government. The town has a population of about 100,000. Officials said, President Hu Jintao and Premier Wen Jiabao have ordered local authorities to go all out to save the disaster-stricken people. Vice Premier Hui Liangyu has rushed to the quake-hit region. The quake also killed five people and injured one another in the Shiqu County, which neighbors Yushu, in the Tibetan Autonomous Prefecture of Garze in Sichuan Province, local authorities said.
