Is this one of the deepest sinkholes ever?

Looking at this might give you a bit of a sinking feeling.

This giant sinkhole opened up on a farm in an area of New Zealand called the Bay of Plenty.

It's 200 metres long and 30 metres wide!

Sinkholes are caused by water dissolving limestone below the surface of the earth.

Science volcanologist Brad Scott said this one has the potential to get even bigger.
