Looking like a landslide on any over-grazed hill, this submarine slide off East Cape is tens of thousands of times bigger. The slide occurred on a slope about the same height as Mt Cook. Blocks, some larger than Mt Ruapehu (18 kilometres wide), travelled nearly 50 kilometres out across a completely flat abyssal floor. Fortunately, it probably happened more than 155,000 years ago. It is thought that the slope may have been destabilised by a volcanic seamount on the Pacific Plate carried along towards and under the Australian Plate.
