On 23 January 1556 in Shaanxi, China, a devastating earthquake took place. It was the era of the Ming Dynasty. Most of the people were living in artificial caves at that time. The epicentre of the earthquake was the Wei River Valley in Shaanxi Province. More than 8,30,000 people got killed as the artificial caves collapsed. Places as far as 500 kilometres from the epicentre were affected.
