WELLINGTON: A new sinkhole on a North Island farm as deep as four double-decker buses and nearly the duration of two football fields has grabbed the attention of New Zealand volcanologists.
The chasm appeared after heavy rainfall close to the town of Rotorua and left a jagged scar at the panorama, exposing rock deposits from 60,000 years ago.
Experts believe rain dissolved underground limestone over hundreds of years, in the end causing the ground to collapse and create the canyon.
"This is pretty spectacular, it's a lot bigger than the ones I'd normally see," volcanologist Brad Scott stated of the chasm measuring 20 metres (66 foot) deep and 200 metres (660 ft) lengthy.
Scott stated the dairy farm the place the fissure appeared lay at the crater of a long-dormant volcano.
"What I see in the bottom of the hole is the original 60,000-year-old volcanic deposit that came out of this crater," he advised TVNZ.
Farmer Colin Tremain stated the sinkhole appeared in a single day remaining week and was once noticed through considered one of his employees throughout an early morning spherical to wait the cows.
While such holes have been common at the belongings, this was once through some distance the most important he stated, admitting there was once little he may do to forestall his land disappearing in such dramatic fashion.
"(I'll) put a fence around it and forget about it, waste of time filling it in," he advised Radio NZ.
