200m+ Sink Hole eats up a Campsite in Queensland
Sink holes are mysterious things that just seem to happen without any warning anytime and any place. We know that some areas are more prone to this and building roads for example over mine shafts that could collapse doesn’t help too! In recent times though there has been more reports of these appearing and a sink hole is never more exciting and exotic than when it appears on a beach in Australia. they cause instant devastation and if in built up areas could take many lives. Late last Saturday this sink hole suddenly appeared below a small campsite on the Coast in Australia devouring a number of tents and even a car and caravan too! as far as we know no injuries occurred but up to 300 people or more were quickly moved off the area affected.

Around 200 metres of the beachfront and 50 metres of a popular campground at Inskip Point near Rainbow Beach have now collapsed into the 3-metre deep hole. A similar sinkhole emerged in 2011 at the same campsite, and geoscientists are now investigating how stable the region is, and whether more land is likely to disappear.
So what exactly is a sinkhole? Basically, they occur when cave systems and cavities below ground collapse, and the sand or soil on the surface starts funnelling into them. This can be dangerous enough, but when water is involved, that falling land can start to behave like quicksand, sucking in everything in reach. This is what happened here, and back in 2013 in Florida, when a man was killed when his bedroom collapsed into a sinkhole.
Sometimes these underground cavities just naturally collapse to produce sinkholes, but they’re often triggered by heavy rain or flooding, which destabilises rocks beneath Earth’s surface. Scientists have shown that something as simple as emptying a swimming pool is enough to trigger a sinkhole.
Earthquakes can also trigger the collapse, but despite a few recent small quakes in Queensland, scientists have ruled this out as a possible trigger for the Inskip Point sinkhole.
“This area has a history where sinkholes occur regularly, it is something to do with the way sediments are formed and the way water moves through the Earth over millions of years or thousands of years,” geotechnical engineer Allison Golsby from consulting company ConsultMine told the ABC. “An earthquake can trigger a sinkhole from a cavity but it has to basically happen on the day or in a very close time frame to the earthquake. In this case I don’t see the link.”
According to a camper who evacuated the site, the sinkhole sounded like a thunderclap as it opened up, and it quickly started pulling in land.
