Mr Bloom   10 #1 Posted February 3, 2014 I'm intrigued/scared to death of these!  Have you seen the one in High Wycombe that appeared yesterday?  http://www.bbc.co.uk/news/uk-england-beds-bucks-herts-26010192  The first thought that came in to my mind was, I wonder how far the nearest 'fracking' 'test' site is away. I wonder if fracking could encourage sink holes? Someone on here much more knowledgeable than me might have the answer, I thought.  For others interested, there's an horizon programme about sink holes on bbc2 in 15 minutes time.  I'll be watching (through my fingers!).

megalithic   10 #2 Posted February 3, 2014 Well fracking causes seismic activity, so i'd say a definite yes. Share this post Link to post Share on other sites Share this content via...

gimp27   10 #5 Posted February 3, 2014 How could fracking cause that? Chalk mining, on the other hand...    Fracking is blamed for everything. Do you think a reverse symnosis fracking exercise caused our beloved hole in the road to disappear overnight? Or was it all the chalk discarded from Redgates, on its closure?

Mr Bloom   10 #6 Posted February 3, 2014 So, the one in High Wycombe has been put down to lots of rain recently and underground mines in the area. How 'at risk' are we in Sheffield? Certainly we've had roads with severe structural damage after the flood. It certainly rains a lot.  Megalithic, did you watch the horizon programme?

megalithic   10 #9 Posted February 3, 2014 I'm not quite sure what you mean. 2.6 what?  The sink hole, like almost all sink holes looks like a collapse due to mining, or dissolved minerals.  2.6 on the Richter scale. That's no small event, and if the conditions are right i don't see how anyone could rule it out. Share this post Link to post Share on other sites Share this content via...
Mr Bloom   10 #10 Posted February 3, 2014 2.6 on the Richter scale. That's no small event, and if the conditions are right i don't see how anyone could rule it out.  This is my thinking.  If a site is predisposed to sinking and fracking takes place, I fear fracking nearby might severely increase the risk/act as a catalyst.

SpikeMac   10 #11 Posted February 3, 2014 2.6 on the Richter scale. That's no small event, and if the conditions are right i don't see how anyone could rule it out.  It is a fairly small event. Then again, so is the sink hole.  Do they frack in the chalk of High Wycombe?  They have certainly mined there. Share this post Link to post Share on other sites Share this content via...
Nagel   10 #12 Posted February 3, 2014 (edited) I can't believe that otherwise sane and intelligent posters on here can believe that 'fracking' is responsible for the sink hole in High Wycombe.  There isn't any 'fracking' going on at the moment in England.  And 2.6 on the Richter scale is tiny.
