Massive New Zealand sinkhole impresses scientists

A farm worker in Rotorua, New Zealand, recently stepped outside to round up cows for milking, and stumbled upon what could be the country's biggest sinkhole to date. With a length that could neatly fit two football fields inside of it, this sinkhole is definitely turning heads. Volcanologist Bradley Scott, of New Zealand research institute GNS Science, called this one "pretty spectacular".

A farm hand that was driving a motorcycle at dawn was the one to discover this sinkhole by nearly falling into it.

Tremain says he's planning to install a fence so livestock don't fall into the sinkhole.

Farm director Colin Tremain informed Newshub television he did not realize just how big the gap was until he saw it in the daytime. "They can spot danger".

Sinkholes form when rocks dissolve due to groundwater that circulates underneath, forming caverns underground that can eventually cause the surface to collapse, according to the U.S. Geological Survey.

Geologists say it has exposed volcanic deposits that reveal thousands of years of information over the area's volcanic past. Scott told TVNZ that the deposit was covered by ten to 12 meters of sediment, left over from ancient lakes and three meters of volcanic ash.

"I could have died".

Now that New Zealand can claim to have the biggest sinkhole ever in their history, landslide scientists and volcanologists are flocking to the site to examine it up close.
