See a Gigantic Sinkhole on New Zealand’s North Island

Thursday, May 17, 2018

A giant sinkhole measuring about 200 metres long and up to 30 metres wide opened up in the ground on New Zealand's North Island. The hole, which runs along a fault line, appeared after heavy rains in the area.

Layers of geological history can be seen on the walls of the hole, including a 60,000-year-old volcanic deposit. Sinkholes are depressions that gradually form in the ground when water erodes an underlying layer of rock or soil.
