(BBC News) UK aid workers are responding quickly to the recent earthquake in the Qinghai province of China.  The city of Jiegu seems to have been most damaged from the 6.9 magnitude earthquake, which occurred Wednesday morning.   ShelterBox, a disaster relief charity based in Cornwall, sent response teams to China to evaluate the damage.  Other organizations, such as Oxfam and the British Red Cross, are also sending teams and supplies to the victims.  One spokesman reported that China is likewise reacting quickly: “An emergency response co-ordinated by the Chinese government is already underway.  The Chinese authorities have long experience of dealing with natural disasters and have not made an early call for international assistance.”  Already, over 400 people have been reported dead, but hundreds are being rescued from the wreckage.
