Design process: Discover
Regardless of my previous experience within different design processes in the past, from the start I realised I had much to discover.
I needed to discover and collect as much information and data about tsunami risk as possible. This sparked an investigation of how tsunami risk affects my community in Tūranganui-a-Kiwa. My Discover phase can be broken down into three main parts:
- Understanding the Hikurangi Plate Boundary
- Mātauranga Māori perspectives: Understanding tsunami risk
- Examination of data collected in the 2015 Preparedness survey
Understanding the Hikurangi Plate Boundary
My research began with an invitation to attend a
“Slow slip” events are also known as ‘silent earthquakes’ — fault movements that are not felt as they occur over a long period of time e.g. days, weeks, months see Figure 5 (L. Wallace, personal communication, June 22, 2017).
Theis the name for the active condition of the Pacific Plate, as it is thrust beneath the North Island of New Zealand by the Australian Plate’). Currently these two plates are locked, leading to the building up of elastic energy which will eventually be released in future large subduction earthquakes (Wallace, L. personal communication, June 22, 2017). These subduction earthquakes are similar to the ones that caused the Indian Ocean tsunami in the in 2004 and the 2011 tsunami in Japan. Because of the close proximity of to the Hikurangi trench, the risk of a major earthquake could result in a “Local source” tsunami which could hit the shores of the East Coast within minutes . Research into the nature of our indicates that is highly exposed to tsunami. It is crucial to this research that my community understand this hazard and that it is communicated in ways that are relevant and meaningful.
Mātauranga Māori perspectives
As I discussed in my
, nor at the right level to understand the process of collecting indigenous narratives. As a result I decided to stay open to the idea of but steered towards understanding new narratives that could be developed by a community to understand tsunami risk.
2015 Preparedness survey
It was important in the Discover phase to understand how my community perceives tsunami risk and risk management in. In the Tsunami Awareness and Preparedness report 2015 the survey revealed coastal communities on the East Coast of Aotearoa, including , had low levels of tsunami awareness and high expectations of receiving a formal warning before evacuation. Quantitative and qualitative data from the Tsunami Awareness and Preparedness Report (2015) survey highlighted that even though residents understood they lived in a coastal community prone to tsunami risk, they were not necessarily prepared for a tsunami situation .
I decided to look at the survey results, in particular the data collected from Wainui, a suburb in. In table 18 (see Figure 14) it is clear that a good number of residents expect an earthquake to warn them of a local tsunami, however there is still a large proportion of residents who rely on a mixture of communication methods like radio and TV announcements, word of mouth and warning sirens. I found this part of the survey interesting as it echoes back to risk communication and the different methods and messages used to alert people of an impending danger. The next step of my design process should engage with community residents to uncover their needs and gain insights to address the problem whilst understanding what communication method works best for them.
