Job Posting: Field Operations Manager
|
Under the general supervision of the Supervising Engineering Geologist of the Earthquake Engineering Program, the Field Operations Manager uses seismic instrumentation and communication engineering principles to oversee and coordinate the Field Operations Unit in the installation of strong motion instruments at sites throughout the State. This position is responsible for overseeing the operation and maintenance of the instruments in the strong motion network and management of the field operations work in projects associated with contracts through Interagency/Departmental and other Agreements.

PhD position: Understanding earthquake sequences on the western Marlborough Fault System
|
Central Aotearoa-NZ occupies a zone of complex faulting, known as the “Transition Zone”, which marks the transition between our largest plate boundary faults: the Hikurangi Subduction Zone and the Alpine Fault. There is a high likelihood of a >M8 earthquake on these faults in the next 50 years, which could alter the state of stress in the Transition Zone, potentially triggering decades of large (>M7) earthquakes. We currently lack sufficient understanding of Transition Zone earthquake behaviour to accurately forecast the hazard posed by large (>M7) earthquake sequences. To address this, we seek to determine the pattern and frequency of past large earthquake sequences with unprecedented spatial and temporal resolution, using novel paleo-earthquake records from near-fault and on-fault paleoseismic sites. The past earthquake records will be used in time-dependent hazard models and to test earthquake simulations. We seek an enthusiastic and highly motivated student for a fully funded PhD project using on- and near-fault paleoseismology on the western Marlborough Fault System as part of our recently funded programme ‘Ngā Ngaru Wakapuke – Building Resilience to Future Earthquake Sequences”.

Our project aims to develop paleoseismic records that have sufficient spatial and temporal precision to resolve how faults interact to produce large earthquake sequences using new paleoseismic approaches focused on lakes and near fault wetlands which produce absolute earthquake ages an order of magnitude more precise than conventional approaches. This PhD project will focus on paleoseismic records from fault-bounded wetlands and possibly on-fault paleoseismology (e.g. trenches) and/or fault-bounded lakes. We are seeking a candidate with a background in Quaternary paleoenvironmental reconstruction and/or paleoseismology. The successful candidate will be based at Te Herenga Waka – Victoria University of Wellington under the supervision of Associate Professor Jamie Howarth, and Dr Kate Clark (GNS Science). The successful candidate will be integrated into the large, multi-institute research programme “Ngā Ngaru Wakapuke – Building Resilience to Future Earthquake Sequences” and will find collaborative and networking opportunities with a range of other PhD students, postdocs, and researchers at Te Herenga Waka – Victoria University of Wellington, GNS Science, NIWA, University of Canterbury, Massey University and University of Otago. Candidates should apply to Jamie.Howarth@vuw.ac.nz. Please include a complete CV (including academic transcripts) and a letter containing the following information - motivation for applying, research interests and experience, and the name and contact details of two or more academic referees. Applications are open until the 17th of January or until the position is filled. The successful applicant will be expected to take up the position in the first half of 2025.
