At midnight on Thursday (June 10th), the ground near Robe, a tourist destination in southern Australia, suddenly collapsed.The locals woke up and found something huge Sink holeAbout 40 feet (12 meters) in diameter opened along the picturesque Limestone Coast — and citizens are now being urged to move away for fear that the hole will collapse further, Australian news agency Reported by ABC.net..
James Holyman, Chief Executive Officer of the Loeb District Council, told ABC: “It’s down quite a bit, and the Antarctic Ocean is being stirred by pretty big waves. [waves].. “
Australia’s 200,000-year-old Limestone Coast faces significant erosion from constant saltwater waves slamming its edges, but other forces may be working, according to a coastal study at Flinders University in Adelaide. Expert Patrick Hesp told ABC. Recent heavy rains and swells in the sea are likely to have contributed to the appearance of the sinkhole, Hesp said.
The hole is also near a natural water geyser known as a blowhole. Newsweek reported.. When waves erode a cave on a cliff, fumaroles form, slosh deep into the cliff, and eventually become perpendicular to the surface. Occasionally, water is sprayed from the top of these holes, usually at high tide.
Blowholes haven’t been blown away for years, according to Holyman, but the constant wave action in the area is gradually shaving cliffs, making them more susceptible to such collapses. .. A hole survey revealed that the site was still unstable and could collapse further, Holyman said.
