Taupo Volcano (New Zealand)
Lake Taupo’s calm waters hide Earth’s largest eruption from the past 70,000 years. This supervolcano ejected 280 cubic miles of material 26,500 years ago, reshaping the landscape. The resulting caldera formed the lake that tourists now enjoy. However, minor eruptions as recent as 181 AD suggest ongoing activity. Scientists carefully track geothermal signals and subtle ground movements.
