On the territory of one of the farms in northern New Zealand overnight a huge karst dip was established with a six-story building and a length of up to 200 meters. This is written by ScienceAlert.
A funnel crater appeared near the city of Rotorua after a rainfall (170 mm of precipitation in 38 hours).
Farm worker Gabriel Lafalla found a failure on April 30, when he was driving around on a motorcycle in an attempt to drive the cattle to pasture, and almost fell into it.
Such voids in the rock are formed over decades and even centuries of washing out.
The rift in the ground was called "Tomo" or the Grand Canyon of Rotorua, and local scientists were seriously interested in the event, since the failure was formed on the territory of a sleeping volcano for 60 thousand years.
