I think we know who wins this battle. At Ruapehu (New Zealand), it isn't really the lava that is the problem, but the lahars produced by mixing snow, crater lake water and volcanic debris. However, that is not stopping people from wanting to ski on the volcano. Never ceases to amaze me how people assess the riskiness of activities.

Ruapehu, in New Zealand, is starting to show signs it may erupt in the near future. It is a fairly active volcano, last erupting in Septemeber of 2007, but it is also a rather hazardous volcano thanks to the crater lake at the top that could be breached. Combined with the development on the…
Ruapehu is a noisy volcano, showing signs of eruptions on a yearly basis. It is also a potentially very hazardous volcano as it produces abundant lahars and has the capacity to generate a catastrophic lahar if the crater lake at the summit were to be breached by an eruption. This is why Ruapehu is…

After keeping us transfixed for almost two months this spring, Eyjafjallajökull has slowly drifted from the headlines. However, this doesn't mean that interesting things -…
Looks like we should expect an eruption at Ruapehu (New Zealand) any time now. Tremors are ongoing, along with increased volcanic gas emissions (specifically SO2 here) and warmer temperatures in Ruapehu's crater lake. All of these ingredients point to a higher probability of eruption.
However,…
