Tang-shan

The Chinese are at the forefront of this science, though even there, nothing could be done to prevent the awful tragedy of July 1976 when Tang-shan, a city of a million people, was reduced to rubble in a few minutes.[...]After Tang-shan, the Chinese government did not seek outside help but poured its own resources in on an extraordinary scale. Tens of thousands of relief workers arrived to restore services, repair damage and provide medical aid, and Tang-shan was recreated with amazing speed.

On 28 July 1976, China suffered its worst earthquake for four centuries, almost directly underneath the densely-populated city of Tang-shan.[…] The violence of the quake hurled people 2m (6ft) into the air, and within a matter of seconds 95 per cent of Tang-shan had collapsed into rubble. The earth split open into wide fissures and thousands of sink-holes, trees were uprooted and railroad tracks buckled. Amazingly, coal-miners working in the solid rock deep below Tang-shan survived the violent shaking that razed the city above them.
