Every winter skiers flock to Mt Ruapehu, an active volcano with several priors in recent memory: substantial eruptions in 1995 and 1996, a crater lake lahar in 2007 followed by an eruption later that year, and an eruption from neighbouring Mt Tongariro in 2012.
So how risky is it to ski on Ruapehu, and what have we learned from previous eruptions, both recent and historic?
