Investigations of past earthquakes on the Titri Fault, coastal Otago, New Zealand

David J. A. Barrell, Nicola J. Litchfield, Russ J. Van Dissen, N. Wang, B. I. Taylor SIlva, S. Hornblow & Mark W. Stirling
The Titri Fault is a major southeast-dipping reverse fault in coastal Otago, southwest of Dunedin. The fault is up to 90 km long and has uplifted the coastal hills between Dunedin and Balclutha. Activity on the Titri Fault was previously poorly constrained, and the fault has not previously been included in the New Zealand National Seismic Hazard Model (NSHM). Two suspected fault scarps were identified on alluvial fans along the Titri Fault and were investigated...

New Zealand Fault-Rupture Depth Model v1.0: a provisional estimate of the maximum depth of seismic rupture on New Zealand’s active faults

Susan M. Ellis, Stephen Bannister, Russ J. Van Dissen, Donna Eberhart-Phillips, Caroline Holden, Carolyn Boulton, Martin E. Reyners, Robert H. Funnell, Nick Mortimer & Phaedra Upton
This report presents a new and provisional estimate of the maximum depth of rupture on New Zealand’s active faults (“New Zealand Fault-Rupture Depth Model v1.0”) based on a combination of two independent models. The first model uses regional seismicity distribution from a relocated earthquake catalogue to calculate the 90% seismicity cut-off depth (D90) representing the seismogenic depth limit H. This is multiplied by an overshoot factor representing dynamic propagation of rupture into the conditional stability...

Wellbeing approaches to improved decision making in Aotearoa New Zealand

Robyn Ramsden, Lucy H. Kaiser & A. Lo
This report summarises the findings of a GNS Science and Victoria University of Wellington Summer Internship project investigating the use of wellbeing frameworks (specifically, the Living Standards Framework and He Ara Waiora) by government in Aotearoa New Zealand. Specifically, this project examines the interfaces between wellbeing fundamentals and the way that the New Zealand Treasury’s Living Standards Framework is used by different stakeholders in their decision making, measuring and reporting.

Geological mapping and structural analysis from combined field mapping, GPS surveying, photogrammetry and 3D modelling at Crawford Knob, Franz Josef, New Zealand

Matthew P. Hill, Susan M. Ellis, Timothy A. Little & Kirby R. D. MacLeod
Survey work using real-time kinematic (RTK) GPS in tandem with a remotely piloted aircraft system (RPAS) has resulted in detailed surface and structural models of a glaciated outcrop at Crawford Knob near Franz Josef Glacier in the Southern Alps of New Zealand. Crawford Knob is located ~8 km from Franz Josef township on the north-eastern side of the Franz Josef Glacier and exposes structures that were interpreted to have been deformed at ~20 km depth...

'Geologic Champagne' voyage report R/V Tangaroa TAN2006: 26 June - 17 July 2020, Wellington-Wellington

Ingo A. Pecher, Jess I. T. Hillman, Bryan W. Davy, A. R. Gorman, Suzi Woelz, D. Andrew, L. Boettger, A. Dalbeth, P. Gerring, J. Hoffman, A. Macnaughtan, P. Oluwunmi, W. Quinn, A. Shorrock & M. Tankersley
Tangaroa voyage TAN2006 took place from 26 June – 17 July 2020, with an unscheduled port call in Wellington from 29 June – 1 July due to equipment problems. The voyage objectives focused on geophysical studies of seafloor pockmarks on the Chatham Rise, as well as possible pockmarks and contourite deposits in the Bounty Trough. We acquired ~800 km of 2D seismic data, ~500 km of which were in a dense grid designed for high-resolution...

Chatham Islands cabled observatory science opportunities: workshop 23–24 February 2021 summary report

Laura M. Wallace, John Townend, Craig Stevens, Richard L. Kellett, Joao De Souza, Giacamo Giorli, Jess I. T. Hillman, Caroline Holden, Bruce Howe, Daniel Leduc, Nate Lindsay, Joshu J. Mountjoy, William L. Power & Emily Warren-Smith
Our ability to address many key questions regarding physical oceanography, plate boundary processes and marine biodiversity, and to undertake geohazards monitoring in the New Zealand region, is greatly hampered by the lack of access to real-time, continuous offshore monitoring of a range of key observables beneath our oceans, which comprises >95% of our Exclusive Economic Zone (EEZ). Developing the ability to monitor geological, biological and oceanographic processes within our EEZ is required to better understand...

Seismogenesis at Hikurangi Integrated Research Experiment (SHIRE) onshore seismic acquisition field report

Katie Jacobs, Stuart A Henrys, D Okaya, H Van Avendonk, Jenny Black, Dan H. N. Barker, Sapthala C Karalliyadda, E Kurashimo, Wanda R. Stratford, M Savage, R Sullivan, Zane R. Bruce & L Hughes
This report documents the acquisition and archiving of a major controlled source and passive seismic imaging project, the Seismogenesis Hikurangi Integrated Research Experiment (SHIRE). The SHIRE project aims to identify and quantify factors controlling the long-term evolution of the Hikurangi margin and the mode of slip along the subduction megathrust. The components of the data volume were acquired in two phases; between October 2017 – April 2018 (SHIRE I) and February–March 2019 (SHIRE II). The...
