Seismic monitoring of the Auckland Volcanic Field during New Zealand's COVID-19 lockdown [PDF]

Solid Earth, 2021
The city of Auckland, New Zealand (Tāmaki Makaurau, Aotearoa), sits on top of an active volcanic field. Seismic stations in and around the city monitor activity of the Auckland Volcanic Field (AVF) and provide data to image its subsurface.

Age, distance, and geochemical evolution within a monogenetic volcanic field: Analyzing patterns in the Auckland Volcanic Field eruption sequence [PDF]

Geochemistry, Geophysics, Geosystems, 2013
The Auckland Volcanic Field (AVF) is a young active monogenetic basaltic field, which contains ∼50 volcanoes scattered across the Auckland metropolitan area. Understanding the temporal, spatial, and chemical evolution of the AVF during the last c.a. 250 ka is crucial in order to forecast a future eruption.

Composite development and stratigraphy of the Onepoto maar lake sediment sequence (Auckland Volcanic Field, New Zealand) [PDF]

Scientific Drilling, 2021
The accurate and precise reconstruction of Quaternary climate as well as the events that punctuate it is an important driver of the study of lake sediment archives.

Using paleomagnetism to determine the heating effect of lava flows on underlying substrates

Volcanica, 2022
The extent to which heat from lava flows passes into underlying and adjacent materials has significant implications for volcanic hazard studies. Here we demonstrate how paleomagnetism can be used as a tool to determine the heating effects of lava flows ...

Visitation Rate Analysis of Geoheritage Features from Earth Science Education Perspective Using Automated Landform Classification and Crowdsourcing: A Geoeducation Capacity Map of the Auckland Volcanic Field, New Zealand

Geosciences, 2021
The increase in geoheritage studies has secured recognition globally regarding the importance of abiotic natural features. Prominent in geoheritage screening practices follows a multicriteria assessment framework; however, the complexity of interest in ...

Short-Term Eruption Forecasting for Crisis Decision-Support in the Auckland Volcanic Field, New Zealand

Frontiers in Earth Science, 2022
Auckland, a city of 1.6 million people, is situated atop the active monogenetic Auckland Volcanic Field (AVF). Thus, short-term eruption forecasting is critical to support crisis management in a future event, especially to inform decisions such as ...

Cost-benefit analysis for evacuation decision-support: challenges and possible solutions for applications in areas of distributed volcanism

Journal of Applied Volcanology, 2023
During a volcanic crisis, evacuation is the most effective mitigation measure to preserve life. However, the decision to call an evacuation is typically complex and challenging, in part due to uncertainties related to the behaviour of the volcano.

Development of a multi-method chronology spanning the Last Glacial Interval from Orakei maar lake, Auckland, New Zealand [PDF]

Geochronology, 2020
Northern New Zealand is an important location for understanding Last Glacial Interval (LGI) palaeoclimate dynamics, since it is influenced by both tropical and polar climate systems which have varied in relative strength and timing.

Stratigraphy and sedimentology of the Orakei maar lake sediment sequence (Auckland Volcanic Field, New Zealand) [PDF]

Scientific Drilling, 2019
Global paleo-climate reconstructions are largely based on observations from the Northern Hemisphere despite increasing recognition of the importance of the Southern Hemisphere mid-latitudes for understanding the drivers of the global climate system ...

Brief communication: A magma depletion alternative for vent distribution in volcanic fields [PDF]

Natural Hazards and Earth System Sciences
The location of a volcanic vent controls an eruption's hazards, intensities, and impact. Current kernel density estimation methods of future vent locations in volcanic fields assume that locations with more past-vents are more likely to produce future ...
