Current Projects

The 18 March 2007 break-out lahar from Crater Lake, Ruapehu, New Zealand During a prolonged eruption sequence in 1995-96, the summit Crater Lake of Mt. Ruapehu, New Zealand was emptied and a barrier of tephra and blocks deposited over the former outlet area. Eleven years later, on 18 March 2007, the refilling warm, acidic lake breached this fragile natural dam, resulting in the rapid release of over a million cubic metres of water in less than 2 hours at a peak rate equivalent to an Olympic-sized swimming pool every 5 seconds. The torrent of water poured down the steep upper gorge of the Whangaehu River, entraining 3 times is original volume from glacial ice, landslide debris, and older alluvial terraces, before debouching onto a broad low-gradient ring-plain where it flowed in multiple braided channels. After crossing the ring-plain, the flood collected back into a single meandering channel incised into uplifted marine sediments, reaching the coast 200 km away 13 hours later. The foreseen nature of this event meant that maximum scientific information could be obtained by instrumenting the channel as if it were a giant laboratory flume to capture time-series data on key hydraulic parameters from the constantly evolving flow, including seismic proxies for sediment load and flow behaviour, using pre- and post-event airborne LiDAR surveys to map the flowpath and measure geometric changes with sub-metre accuracy, and observer teams to capture video footage and dip-samples, all backed up by traditional forensic sedimentology or the detailed logging and characterisation of deposits. Taken together, these constitute probably the most detailed dataset compiled on a single volcanogenic flood event anywhere in the world, and are already informing new numerical models of lahar behaviour under development by international collaborators including Dr Jonathan Carrivick at Leeds University. Eruption-triggered lahars at Mt. Ruapehu, New Zealand Explosive eruptions beneath the summit Crater Lake of Mt. Ruapehu, New Zealand eject jets of water and rock debris on ballistic trajectories. These impact the seasonally snow-covered upper slopes of the mountain and drain off, forming complex multiphase granular mass-flows dominated by entrained snow and ice. Over the past 150 years, these hazardous lahars have entered areas now occupied by major commercial skifields on 6 occasions. Current research is focussed on understanding new observations and insights obtained from the 25 September 2007 eruption of Ruapehu, coupled with unique video footage of flows generated early in the 1995-96 eruption sequence.
