Some really big sink holes from around the world

Since I wrote about Sink holes in Arizona, I received a link from a friend showing some really big, mostly urban, sink holes. My original post was about the geology of sink holes, but they can also be caused by broken water mains in the urban environment.

The linked article was published by Business Insider and titled: “The Most Terrifying Sinkhole Pictures You’ve Ever Seen.” Below is one example photo. See the complete article here. (H/t Syver More).
