Why Parts of China Are Sinking

It wasn’t until this past June that most people in Tianjin realized that the northern Chinese port city was sinking.

On May 31, fissures appeared on a road in Tianjin’s Jinnan district. Several residential buildings in the surrounding neighborhood had also started to lean, with water seeping through cracks in the walls. Over the next few days, nearly 4,000 residents had to be relocated, local media reported.
