The 5.6 Lake Taupō earthquake on November 30th, lead to a small tsunami on the lake and a fair amount of foreshore damage.
The tsunami swept two boats onto rocks, and a 30 metre section of Four Mile Bay dropped into the water.
The investigation is ongoing, and to explain it further GNS Senior Volcanologist Geoff Kilgour joins Jesse.
