Scientific study of China’s great flood could prove 4,000-year-old legend

Many people died some 4,000 years ago when a major earthquake jolted Jishi Gorge, a deep, rocky Yellow River valley in what is now Qinghai province.
But aside from the immediate death toll, centred in the Guanting Basin several kilometres downstream, with some people buried at the entrances to collapsed cave dwellings as they tried to flee, it was a prelude to an even greater catastrophe – China’s great flood.
