Recently there has been quite a lot of reports of sink holes appearing particularly in China. My link

Is this occurence a coincidence or due to some specific cause?

What do others think?

Looks like most of them are down to heavy rain.. Not just in China either..

When I was a youngster in South Africa we had serious problems with sinkholes in a town called Carltonville. Whole blocks and houses would be swallowed by these. The cause was water being pumped out of the ground because of mining operations and the resulting voids or caverns collapsing.
