Another 'sinkhole'?

Recommended Posts

What lucky sod gets the pleasure of squeezing through the opening. How much of the country was mined through the years? Could it push prices down in certain (at risk) areas? Are these sinkholes confined to past/present mining areas?

Anyone wanna wager that most (all?) of these sudden residential area ground collapses are sites that (i) are predominantly modern housing, and (ii) were classed as 'brownfield' ????

Wonder how the typical home insurance policy covers this sort of thing?

Sinkholes are more likely to occur where the ground has been very wet, the water erodes a cavity under the ground in certain types of rock, when it dries out causes a vacuum sucking anything on the surface into it.

This is why Miami in the USA is rife with them and also why it happens where land has been developed as the subsurface dries out when concreted over.

So living on a flood plain may not be a good idea, depending on the rock composition. Fracking could also be very unhelpful, just as mining areas tend to suffer from subsidence.

The problem with sinkholes is when they strike you get no warning and then you are gone. Just glad I live in an area where the rock is granite.

"Sinkholes" is actually a special keyword to tell the important people to make a move with regards to certain finances. That's my guess. Stories of this type simply did not make the news before.

Are you not worried about the other problems in a granite area?
