The crater caused by ocean tides measures 25 feet deep and about 980 feet wide — and authorities fear another one will likely appear in the area soon.
A large portion of a beach in Queensland, Australia has been swallowed up by a massive sinkhole.
The crater emerged overnight on Sept. 23, to the shock of locals and visitors alike — and the video of the aftermath is jarring.
The “nearshore landslip,” as it has been described, happened on Rainbow Beach at Inskip Point, with the crater measuring about 200 to 300 meters (650 to 980 feet) wide and 7.5 meters (25 feet) deep.
This is the third sinkhole of this kind at this Australia beach in three years.
Diana Journeaux from Rainbow Beach Helicopters told the Brisbane Times that she didn’t see the sinkhole when she flew on one of her choppers on the morning of Sept. 23, indicating that the incident happened in a matter of seconds.
Authorities advised beachgoers and campers to steer clear of this particular area, as the threat of being suddenly swallowed is very real.
Queensland’s Department of Environment and Science responded to the incident in a statement:
“It’s likely this erosion has been caused by the undermining of part of the shoreline by tidal flow, waves and currents. When this occurs below the waterline, the shoreline loses support and a section slides seaward leaving a hole, the edges of which retrogress back towards the shore.”
This area of beach seems to be prone to erosions of this nature. Back in Sept. 2015, a similar sinkhole appeared just a few hundred meters away from the site of this latest crater. Another one appeared in 2016 as well, and authorities believe that this latest sinkhole won’t be the last one that’s seen in the area.
“We could see another one in 12 months, or we could see one in a few years,” Peter Davies from the University of the Sunshine Coast told the Australian Broadcasting Corporation. “All we can say with any certainty is that it’s an inherently unstable area and will do this periodically.”
Sinkholes typically happen when rainfall seeps into the soil, causing the ground to be less stable and effectively fall into itself. This particular occurrence happened because of tidal flow from the ocean.
Geotechnical engineers are currently monitoring and examining the situation. There are no reported injuries at this time, though a man’s car and caravan have fallen victim to the expanding hole.
