ABSTRACT On 14 November 2016, the Mw 7.8 Kaikōura earthquake and tsunami occurred in Aotearoa New Zealand, impacting the city of Te Whanganui-a-Tara (Wellington). As many people reside in apartments in Wellington, we undertook a survey followed by interviews to understand evacuation information communicated to apartment dwellers, and how residents used that information for decision-making. Immediately following earthquake shaking, some apartment dwellers stayed in their building as per official advice, while others evacuated because they felt safer outside. A small proportion evacuated because of the tsunami threat, and many of these participants did so because of the ‘Long or Strong, Get Gone’ evacuation advice. Others were unclear whether their apartment building was in a tsunami evacuation zone. Some returned immediately after the initial evacuation, while others with damaged apartments evacuated for weeks to months. Participants used regular information upates particularly via social media channels, to inform decisions about returning after longer-term evacuation. However, communicating with the Body Corporate or landlord was difficult, and apartment dwellers reported having trouble getting information about the damage status of their building, making decisions about returning challenging. Given the unique context of apartment dwellers, communication strategies should be honed to assist responses to a future event.

ABSTRACT The north-striking sinistral reverse Papatea Fault ruptured with a very large (up to 12 m) oblique slip as part of the 2016 M W 7.8 Kaikōura earthquake in the northeastern South Island. Paleoseismic studies were undertaken at three sites along the Papatea Fault, named Murray’s roadcut, Jacqui’s Gully (both on the main strand), and Wharekiri trench (western strand). These sites provide evidence for up to three Late Holocene paleoearthquakes prior to 2016 (=E0) on this previously unmapped active fault, with preferred OxCal-modelled timings of 98–149 (E1), 546–645 cal yr BP (E2), and >738 cal yr BP (E3). Event correlations between the sites are generally consistent across these past events, implying that the two strands of the Papatea Fault link at depth and rupture together co-seismically as in 2016. Comparisons of its paleoseismic record with the Kekerengu Fault and uplift data from Waipapa Bay and Kaikōura, suggest that the Papatea Fault may have three distinct rupture modes: (i) Kaikōura-type multi-fault ruptures with multi-metre, anelastic block displacements and associated major landscape change; (ii) multi-fault earthquake ruptures with other regional fault combinations; and (iii) single-fault Papatea ruptures with metre-scale displacement. OxCal models offer the possibility that the E1 fault rupture occurred in 1855 CE.

ABSTRACT We present a suite of 15 palaeogeographic maps illustrating the geological evolution of the entirety of Zealandia, from mid-Cretaceous to present, highlighting major tectonic phases, from initial Gondwana rifting through to development of the Neogene plate boundary. They illustrate palaeobathymetric and palaeofacies interpretations along with supporting geological datasets and a synthesis of regional tectonics. The maps are underpinned by a geologically-constrained and structurally-based rigid retro-deformation block model. This model, tied to the global plate circuit, is relatively simple for the main regions of Northern and Southern Zealandia, but breaks central Zealandia into numerous fault-bounded blocks, reflecting complex Neogene deformation associated with the modern plate boundary. Production of maps using GPlates and GIS allows for simple alteration or refinement of the block model and reconstruction of any geological dataset at any time. Reconstructions are within a palaeomagnetic reference frame, allowing assessment of palaeo-latitude, critical for palaeo-climatic and palaeo-biogeographic studies.
