Saturday, May 5, 2018, 4:28 PM - A giant sinkhole that opened up on a farm in New Zealand's Bay of Plenty on April 30 has revealed a 60,000-year-old volcanic deposit, local media reported.
Running along a fault line, the sinkhole opened after heavy rainfall in the area.
According to local broadcaster TVNZ, the length is around 200 metres (656 feet), with a width of 20 to 30 metres (65-98 feet). It's equivalent to the length of two football fields and the depth of a 6-storey building.
While sinkholes are common in the area, the size of this sinkhole has excited the science community with volcanologist Bradley Scott calling it "pretty spectacular."

A worker stumbled on the chasm earlier this week when he was rounding up cows for milking.
"It's not a new process, it's been happening for a long time," said volcanologist Bradley Scott. "And we can expect it to happen again in the future."
