A cluster of enormous sinkholes in northwest China

Forty-nine vast sinkholes have been discovered in the mountains in Hanzhong city of northwest China’s Shaanxi Province. The discoveries were made during a survey conducted over the past four months. Sinkholes are a type of natural cave with a diameter and depth of over 100 meters.
