TY - JOUR PY - 2019// TI - Descriptive epidemiology of New Zealand's highest mortality earthquake: Hawke's Bay in 1931 JO - Scientific reports A1 - Clement, Christine A1 - Abeling, Shannon A1 - Deely, Joanne A1 - Teng, Andrea A1 - Thomson, George A1 - Johnston, David A1 - Wilson, Nick SP - e4914 EP - e4914 VL - 9 IS - 1 N2 - In this study we aimed to produce the first detailed analysis of the epidemiology of the severe injury and mortality impacts of the 1931 Hawke's Bay earthquake in New Zealand (NZ). This involved the compilation and analysis of archival data (hospitalisations and deaths) including the examination of 324 death certificates. We found that there were 662 people for whom some hospitalisation data were available at four weeks post-earthquake: 54% were still in hospital, 4% were still classified as "serious", and 5% had died (nā=ā28). Our classification of death certificate data indicated 256 earthquake-attributable deaths and for another five deaths the earthquake was estimated to have played an indirect role. There were 15 buildings associated with three or more deaths each (accounting for 58% of deaths with a known location). Many of these buildings were multi-storey and involved unreinforced masonry - with some of this falling into the street and killing people there (19% of deaths). In contrast, deaths in homes, which were typically of wood construction and single stories, comprised only 3% of deaths. In conclusion, this earthquake had a relatively high injury impact that appears partly related to the lack of regulations for building construction that would mitigate earthquake-related risk. Such regulations continue to be of relevance for New Zealand and for other countries in earthquake zones.
