Te Hiranga Rū QuakeCoRE extends its congratulations to Lauren Vinnell, Piata Inch, David Johnston and Nick Horspool on the conferral of the prestigious Earthquake Engineering Research Institute (EERI) 2022 Outstanding Paper Award in San Francisco last night. Lauren and David were at the EERI 2023 Annual Meeting to receive the award on behalf of all co-authors. The Outstanding Paper Award is awarded to authors of Earthquake Spectra papers ‘judged to be outstanding contributions to earthquake hazard mitigation.’
Their paper “Behavioral responses to earthquake shaking: Video footage analysis of the 2016 Kaikōura earthquake in Wellington, Aotearoa New Zealand,” (Earthquake Spectra, Vol. 38, No. 3, pp. 1636-1660), by Lauren Vinnell, Piata Inch, David M. Johnston (M. EERI 2013), and Nick Horspool was novel in multiple ways.

Thanks to video footage kindly provided by the Wellington International Airport the team were able to analyse what people actually did during the 2016 Kaikōura Earthquake. This relatively new method hasn’t been used very often in the context of earthquakes but has some clear strengths that compliment other more traditional data-gathering types. Typical methods are centred around intent and reflection. Asking people what they think they’ll do in an earthquake, or retrospectively asking them to self-report on what they did do. While these two approaches can provide valuable data they have some obvious limitations. Vinnell notes “Intentions are a good predictor of behaviour but aren’t perfect, while people sometimes forget exactly what they did and why or give us what they think is the ‘right’ answer." Additionally, “video footage is more objective, so we aren’t relying on people accurately predicting or reporting their own behaviour”.
The award citation notes “Vinnell et al.’s. use of CCTV shows how detailed analysis of actual behaviour during earthquakes may inform the community to reduce the risk of injuries and fatalities through behaviour modifications.”
The video footage also provides other valuable avenues for analysis. Particularly how people respond to different aspects of the earthquake such as weak and strong shaking or environmental cues over time. This aspect coupled with how people interacted with each other during the Earthquake is the focus of another paper currently underway by the group. “In the footage, we saw people interacting with each other (people they were with as well as strangers) as they tried to work out what was happening and what they should do."
"There’s some really important findings in there to help us understand not just what people do during earthquakes but why.”

The multidisciplinary authorship team is made up of:
The EERI judges specifically noted the multidisciplinary nature of the paper, Vinnell elaborates that this “reflects a really exciting shift towards greater collaboration between the social and physical sciences. It’s an acknowledgement that working together can help us answer some tricky questions in ways which can benefit a large number of fields. We’re getting good at this pretty quickly in Aotearoa, so to have it acknowledged by the leading earthquake engineering organisation in the United States shows that again New Zealand research is getting noticed and having an impact globally.”
“Winning the award means a lot, particularly given most of the team are very or fairly early in our careers, so the recognition of our work is really valuable.”

In the days following the EERI 2023 Annual Meeting Vinnell, Johnston and a colleague from the United States Geological Survey (USGS) are travelling to Redding, California to attend an interagency meeting to build on work with Washington State around their volcano and earthquake hazards.
QuakeCoRE partially funded the research for the initial paper and continues to support the ongoing research underway.
