Short summary
In this study, we use cosmogenic-sourced 3He to determine the eruption ages of 23 lava flows at Mt Ruapehu, Aotearoa New Zealand, and we show how this method can help overcome challenges associated with traditional dating methods in young lavas. Comparison with other methods demonstrates the accuracy of our data and the method's reliability. The new eruption ages allowed us to identify periods of quasi-simultaneous activity from different volcanic vents during the last 20 000 years.
