A giant sinkhole has opened up on a dairy farm in New Zealand, exposing rock deposits from a 60,000-year-old volcano.
The hole, which has actually captured the attention of volcanologists, is as deep as four double-decker buses (20 metres or 66 feet) and is 200 metres (660ft) long.
It appeared after heavy rain near the town of Rotorua on the North Island, an area renowned for its geothermal activity.
Geologists think that countless years of rain deteriorated underground limestone, triggering the ground to collapse.
“This is pretty incredible, it’s a lot larger than the ones I ‘d usually see,” volcanologist Brad Scott stated.
Mr Scott informed TVNZ the dairy farm was positioned above the crater of a dormant volcano.
The dirt in the bottom of the sinkhole was “the original 60,000-year-old volcanic deposit that came out of this crater”, he said.
The farmer, Colin Tremain, said it had actually appeared overnight and was identified by an employee on an early morning run to manage the cows.
Comparable sinkholes prevail on his farm, Mr Tremain included, however this is the biggest – and there was absolutely nothing he might do to stop his land vanishing.
He told Radio NZ he could “put fence around it and ignore it” but it would be a “waste of time filling it in”.
