little drone diggers fitted with sensors the size of cats attached to cables could go down a bit further under the sinkhole to get better underground topology readings
Council surveyors could have new jobs surveying underground topology with sonar radar and other technology looking for trouble spots
Yeah apparently it was caused by a subterranean creek or river.

don’t get me started…
actually it appears as though it was the result of a cap on a shaft breaking away and sinking into what was obviously a flooded void…
It’s always wise to avoid a void.

Many years ago I suggested that a remote control snake would be the best device to get through holes in caves too small for humans to get through. Independently of my suggestion that was followed up and I now frequently see on TV someone putting long optic fibre sensor-cables through small holes underground to get a good look at what is there.
I still hold to the view that you can get a full 3_D topology in places like caves with a single camera. In it’s simplest form just use two images from the camera to build up a stereoscopic view, in more accurate form every frame of the movie is used together.

can somebody save the clothesline
why wont people think of the clotheslines

recent photos show they have saved the four concrete storks and the witches hat.

What I fail to understand is where all the water came from. I doesn’t look as if it was filled up by a garden hose.
I’ve mentioned before that I know someone personally who has a sinkhole in their back yard. They live in the Florida panhandle.

Underground river?

A professor dude from UQ was on the radio this morning was saying the sinkhole was caused by a capped exploration hole and water had rotted away the wooden posts propping it up… or something.

I would imagine Nudists standing next to that wet hole would have their butts clenched so hard they would need new sphincters

I reckon over time you could create a sinkhole in your backyard, turn your hoses up full and use the water pressure to bury them into the ground as long as the length of the hose and just leave them

I tried this as a kid, trouble is the hose doesn’t follow a straight line down, goes in all directions.

it was a flooded shaft with a cap on top… probably held in place by a series of old railway sleepers… the sleepers rot and fail, the cap sinks into the flooded void and what you get the is washing machine effect you see in the video that was linked to in the news articles…
The neighbors would be thinking about the underground topology around that sinkhole.

what is this underground topology you speak of… it’s most likely that is was a vertical shaft, so the effects will be very localised.
If only there was some way of imaging the subsurface.
The mayor of Ipswich was saying this morning that he got a message from someone in the US thanking him for his compassion and will he run against Trump. (The mayor has paid for a hotel room for the residents until the hole can be fixed)

We need technology to image the subsurface.
councils could look for covered old mine shafts, check along water mains for leaks that could cause sinkholes, look for trouble spots

Yes, if I was a neighbour I would be very very nervous.

The CSIRO people I worked with developed a self-propelled robot with camera that could roll underwater up and down pipelines imaging the subsurface. Actually two different teams of CSIRO people I worked with. One built the self-propelled underwater robot and the other wrote the visual processing software.
That robot was intended to work in a pipeline, though. It trundled along on wheels. Wheels wouldn’t be a great propulsion method in sinkholes.

A sinkhole robot design like a mini submarine
perhaps a robot design with a drill head at one end, sensors in the middle and a propeller at the other end with the retrieving cable attached to the center of the propeller
cable kept clear of propellers using an extended shaft attached to the center of the propeller

I don’t like guessing underground topology that been altered by nature or by mankind
be good to get something down there to have a look around etc
just being cautious
