title: Evaluating earthquake hazard and risk using liquefied volcanic-ash layers in lakes

authors: Lowe, David J.

subjects: tephra seismites

abstract: Liquefied volcanic-ash or tephra layers, for which we have coined a new term, ‘tephra seismites’, are preserved in lake sediments in numerous 20,000-year-old lakes in the Hamilton Basin in northern North Island. Up to five tephra layers in cores taken from the lakes show signs of liquefaction - the phenomenon seen during the Christchurch earthquakes - that include disrupted tephra layers, voids, and dykes (injectites). These features show that one or more of four newly-discovered ‘hidden’ faults in Hamilton (see map) were responsible for previously unrecognised prehistoric earthquakes within the past 20,000 years (Kleyberg et al., 2015). Around 30 lakes are scattered amidst the faults, and hence cores are being taken from almost all of these to build up a picture of which fault(s) may have been active in that time. We anticipate that lakes closest to faults that have been active will show more tephra seismites than those farther from the faults.

title: Linguistics of social media: An introduction to the special issue

authors: Calude, Andreea S.

abstract: It is hard to remember a world without social media (SM). The Internet Relay Chat (IRC) and bulletin boards of the 1980s and the popular early platforms of the 1990s, MySpace, AOL Messenger, and Facebook, gave rise to nothing short of an SM empire in just 50 years. Although we have been considering how language is used on the Internet for some time now, studying the language used on SM is comparatively a newer field of inquiry.

title: Waikirikiri Marae: Shared experiences of the wharemate

authors: Rua, Hare

subjects: Māori

abstract: In Te Urewera, wharemate (shelters in which the deceased receive their final farewells) have traditionally been temporary structures. In the 1980s, a new practice was introduced in the Ruātoki valley with the erection of permanent wharemate facilities. One was erected at Waikirikiri marae (tribal meeting grounds and associated buildings) in 1989. Knowledge and discussion regarding wharemate at Waikirikiri marae have changed over the years, and a whole generation has not been fortunate enough to experience tikanga (correct procedures, customary practices) that prevailed prior to the introduction of the permanent wharemate building that is there today. These changes are recorded in this paper through the shared stories of three kaumātua (elders) from Waikirikiri.

This paper is a summary of Hare Rua’s thesis study, the data for which was collected in 2009. This work forms part of the Tangi Research Programme, a collaboration between the School of Māori and Pacific Development and the Māori and Psychology Research Unit at The University of Waikato, Hamilton, New Zealand.
