title: Tephra seismites - Understanding seismic hazard of hidden faults by analyzing liquefied tephra layers in lakes

authors: Kluger, Max O.

abstract: Assessing seismic hazards in regions with hidden or poorly expressed faults is one of the major challenges in paleoseismology today. Here, we used computed tomography imaging to quantify the dimensions and distribution of liquefaction structures in ≤17.5-thousand-year-old tephra layers in 18 lakes scattered across the poorly expressed Hamilton Basin fault system in northern New Zealand. These "tephra seismites," embedded in unconsolidated, organic-bearing lake sediment, increase in occurrence and dimensions toward known faults and indicate the occurrence of a local hidden fault segment. Through incorporating peak ground acceleration modeling, we found that the spatial distribution of tephra seismites directly relates to the ground shaking induced by near-field fault ruptures. We used the variability in tephra seismites within the stratigraphic record and tephrochronology to better constrain the recurrence intervals and magnitudes of paleoearthquakes from both the Hamilton Basin and adjacent Hauraki Basin fault systems. Our methodology is globally applicable in volcanic and tectonic regions where liquefaction structures are preserved among (hidden) faults.

title: Researching our own practice

authors: Spiller, Dorothy

abstract: In this chapter, we argue that using research to inform our teaching is a vital element in the reflection process and empowers us to keep developing our teaching in ways that can be transformative for ourselves and our learners.

title: Te Puni Rumaki – Strengthening Māori medium initial teacher education

authors: Tamatea, Karaitiana

abstract: The delivery of initial teacher education for Māori medium contexts in Aotearoa seeks to support the revitalization of the indigenous language and practices in collaboration with the current education system. This presentation introduces a research project begun early in 2013 with providers, student teachers, schools and communities involved in respective Māori medium programmes. This research project has a "positive output approach" where fundamental elements to the success of these various programmes are shared. The wide range of Māori medium initial teacher education settings is investigated. Consequences from the research findings will also be discussed.
