The supervolcano under Lake Taupō is pushing the lakebed around
Peer-reviewed: This work was reviewed and scrutinised by relevant independent experts.
The bed of Lake Taupō is rising and falling as magma moves around in the active volcano lurking below. Researchers looked at 42 years of measurements recording miniscule changes in the lakebed, finding the northern end of the lake had sunk by 14mm. However that has been interrupted by 16cm of uplift, which the researchers say is possibly due to magma moving closer to the surface during periods of unrest.
