Sinkholes, work of nature or greed?

I turned the papers up, down, left, and right when I read the news. The image seems so incredible. Certainly the work of an overzealous photoshopper, I thought.

Apparently, such sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds or rocks that can naturally be dissolved by ground water circulating through them (source: U.S. Geological Survey). The pictures of such ‘formation‘ on Wiki are pretty in the natural setting but absolutely devastating when it happens in the middle of downtown.

The storm did not do this to Guatemala. It simply tightened the dead knot, fastened by some people.

I don’t know about the bed of Singapore. I really won’t want to see a HDB flat disappearing into the earth. There must be more accountability in the parties who are responsible for construction and drainage. Don’t forget what happened in Qinghai and Sichuan, China. Painful lessons (for the people) are everywhere.
