We formally introduce 14 new high-level stratigraphic names to augment existing and hierarchically organise all of New Zealand's onland offshore Cambrian–Holocene rocks unconsolidated deposits. The two highest-level units are Austral Superprovince (new) Zealandia Megasequence (new). These encompass the country's Cambrian–Early Cretaceous basement Late Cretaceous–Holocene cover sediments, respectively. Most constituents in current common usage: Eastern Western Provinces consist 12...
Abstract. The water quality of Lake Rotorua has steadily declined over the past 50 years despite mitigation efforts recent decades. Delayed response groundwater discharges to historic land-use intensification ago was reason suggested by early tritium measurements, which indicated large transit times through system. We use isotopic and chemistry signature for detailed understanding origin, fate, flow pathways, lag future loads contaminants. A unique set high-quality data more than four...

Taupō volcano (New Zealand) is distinguished as the source of Earth's youngest supereruption (∼25.5 ka), with Lake occupying resulting caldera. has also produced eruptions a wide variety sizes, styles and associated landscape responses over ∼350 kyr period. Early (>54 ka) poorly demarcated, merging Maroa to north, represented by widely scattered, geochemically distinct, effusive domes explosive eruption products from vents all around modern lake. had two independent magmatic systems 54–25.5...
Abstract The evolution of the continental intraarc Taupo Rift in North Island, New Zealand, is rapid, significantly faster than comparative intracontinental rifts such as African Rifts. Based on our faulting data and published geological, geophysical, borehole data, we show that activity ~2 Ma has rapidly asymmetrically narrowed via inward eastward migration (at rates approximately 30 km Myr −1 15 , respectively) propagated southward along its axis ~70 350 kyr. loci voluminous volcanic...
Abstract. Evacuation of the population from a tsunami hazard zone is vital to reduce life-loss due inundation. Geospatial least-cost distance modelling provides one approach assessing evacuation potential. Previous models have generally used two static exposure scenarios and fixed travel speeds represent movement. Some analyses assumed immediate departure or common time for all exposed population. Here, method proposed incorporate time-variable exposure, distributed speeds, uncertain into an...
