How terrible for this couple? I feel so sad for them. The neighbours must be starting to worry if their home will be next.
We live in an old mining town and one part is regarded as to dangerous to build any houses there, but nobody really knows how many old mine shafts are really there. 150 years ago they did not keep plans and locations very accurate as has to be done today. Every time we get an earth tremor, the locals are joking that one day one of us will be swallowed up, house and all. Our town is sitting on an earthquake fault line.
It's not funy anymore when one sees what can happen.
Last earthquake was 6.2 Big enough to shake the house and sounding like a Semitrailer drove through our house. This silent sinkhole is so frightening. It can happen to anyone while they are sleeping.
I hope they find the real cause and a permanent solution soon.
