China said that there was a heavy loss of life in the earthquake which struck Tangshan city yesterday. Survivors said that Tangshan, an industrial city of one million people 160 kilometers east of Peking, was completely destroyed. Observers living in Beijing said it appeared that only a small part of the one million inhabitants escaped death or injury.
Many of the men of Tangshan were working in the mines deep under the earth's surface when the earthquake occurred. Unfortunately, few of these miners have survived. A lot of people were also working in the city's offices. Regrettably, most were killed under falling concrete when the building collapsed. The Chinese authorities have not yet given any information about the actual number of casualties, but it is thought that tens of thousands of people have been killed. Hardly a building has been left standing.
