Mt Ruapehu Crater Lake lahar hazard
This report documents the results of some additional computational hydraulic modelling of the historic 1953 lahar event down the Whangaehu River (which caused the Tangiwai disaster) and a hypothetical lahar event generated by a future collapse of the Mt Ruapehu Crater Lake outlet barrier. Based on the results of the additional work, the following conclusions were obtained regarding the lahar ev...

The toxic element arsenic is widespread in New Zealand’s aquatic and terrestrial environments. Arsenic is ubiquitous in all of the geothermal areas and waterways that fall within or pass-through the Taupo Volcanic Zone, an area in the central North Island that stretches from Mt Ruapehu to White Island (Figure 1). On its way to the surface, super-heated geothermal water dissolves appreciable amo...
متن کاملChanges in substrate and diet of blue duck on Tongariro River after the 1995 Mt Ruapehu eruption (Part 1 of 2)
Sampling of three sites on the upper Tongariro River was carried out in summer (January) 1996 to evaluate impacts of the Mt Ruapehu eruption and subsequent flushings of accumulated sediment from behind Rangipo Barrage on substrate, periphyton, invertebrates and blue duck (Hymenolaimus malacorhynchos) diet. Levels of sand and gravels increased markedly in summer 1996 in blue duck feeding habitat...
متن کاملGlobal anthropogenic methane emissions 2005–2030: technical mitigation potentials and costs
This paper presents estimates of current and future global anthropogenic methane emissions, their technical mitigation potential and associated costs for the period 2005 to 2030. The analysis uses the GAINS model framework to estimate emissions, mitigation potentials and costs for all major sources of anthropogenic methane for 83 countries/regions, which are aggregated to produce global estimat...
