“…Seven lahar deposits overlying the Taupo Ignimbrite were identified (Fig. 2, sections E, F) (Donoghue 1991;Donoghue & Neall 2001). Purves (1990) and Palmer et al (1993) described the distribution of the Onetapu Formation on the southeast Ruapehu ring plain, where lahar deposits form the most recent constructional surface, the most distinctive feature of which is the Whangaehu Fan (Fig.…”

“…Deposits from the Onetapu Formation represent the last c. 1850 14 C yr of the volcano's lahar history (Donoghue et al 1995;Cronin et al 1997b;Donoghue & Neall 2001 ). They occur on the upper and middle flanks of Ruapehu volcano, on the adjacent ring plain, in the dissected Whangaehu valley (Fig.…”

The Onetapu Formation represents a sequence of at least 17 volcanic diamictons that were emplaced over the last c. 2000 14 C yr by lahars in the Whangaehu River catchment, covering part of the eastern flank of Ruapehu volcano and its adjacent ring plain. Interbedded andesitic tephras from the Tufa Trig Formation help in reconstructing the chronology of volcanogenic events that led to the formation of the Crater Lake basin and its subsequent evolution. Onetapu Formation contains deposits laid down by lahars spanning several orders of magnitude. Channel deposits left by the largest lahars are bouldery to distances reaching c. 50 km downstream from the source region. Much of the coarsest fraction of the medium to smaller lahar deposits (i.e., volume <5 × 10 7 m 3 ) was emplaced close to the source on the Whangaehu Fan, where the river debouches onto the ring plain. Mainly thin, fine grained, pebbly overbank debris-flow deposits are preserved downstream of the fan, with increasing proportions of sandy hyperconcentrated-flow deposits. The largest Onetapu lahars are inferred to have been generated by partial collapse of the wall of Crater Lake as a result of powerful explosive eruptions. In contrast, smaller lahars were the consequence of phreatic/phreatomagmatic activity within Crater Lake, expelling lake waters onto the flanks of the volcano.

“…1), Ruapehu is the largest and most active volcano in the North Island standing at 2797 m high (Lecointre et al 2004;Neall et al 1999). Upon Ruapehu are three summit craters that have all been active over the last 10,000 years (Donoghue and Neall 2001). This includes the current Crater Lake, Te Wai-a-moe, which is situated over the active southern Crater.…”

“…Ruapehu's periodic activity causes a number of hazardous events with evidence of these volcanic hazards recorded in the landscape and represented by the surrounding volcaniclastic ring plain, (Fig. 1) which is made up of fragmented rocks deposited by historical lahars, debris avalanches and some fluvial and glacial deposits (Donoghue and Neall 2001).…”

Ngāti Rangi, an indigenous tribe of Aotearoa New Zealand, live on the southern flanks of their ancestral mountain, Ruapehu, an active volcano. Ruapehu has erupted and caused lahars within living memory, and nearby Tongariro erupted as recently as 2012. Ngāti Rangi and other tribes affiliated to these mountains are intimately connected to and familiar with the moods, signs, and language of the mountains and have valuable knowledge to contribute to decision-making and warning systems during volcanic events. To date this knowledge or mātauranga Māori has been somewhat under-utilised, and Ngāti Rangi have not always been included in decision-making processes during volcanic events. But communication is improving, and Ngāti Rangi have begun a journey of building their own monitoring, information collection, and communication systems. Past and present monitoring, warning systems, communications and tribal civil defence resources are examined to determine how Ngāti Rangi and their tribal knowledge can be better recognised, communications with governmental volcanic hazard management agencies improved to ultimately work together to improve outcomes for the tribe and local community.

Volcanic hazards assessments at andesite stratovolcanoes rely on the assessment of frequency and magnitude of past events. The identification and correlation of proximal and distal andesitic tephra, which record the explosive eruptive history, are integral to such assessments. These tephra are potentially valuable stratigraphic marker beds useful to the temporal correlation and age dating of Quaternary volcanic, volcaniclastic and epiclastic sedimentary deposits with which they are interbedded. At Mt Ruapehu (New Zealand) and Mt Rainier (USA), much of the detail of the recent volcanic record remains unresolved because of the difficulty in identifying proximal tephra. This study investigates the value of geochemical methods in discriminating andesitic tephra. Our dataset comprises petrological and geochemical analyses of tephra that span the late Quaternary eruptive record of each volcano. Our data illustrate that andesitic tephra are remarkably heterogeneous in composition. Tephra compositions fluctuate widely over short time intervals, and there are no simple or systematic temporal trends in geochemistry within either eruptive record. This complexity in tephra geochemistry limits the application of geochemical approaches to tephrostratigraphic studies, beyond a general characterisation useful to provenance assignation. Petrological and geochemical data suggest that the products of andesite systems are inherently variable and therefore intractable to discrimination by simple geochemical methods alone.
