How tsunami risk informs natural hazard management


Tsunami is one of the biggest risks facing
New Zealand and Australia, yet it’s one of the least known. The consequences of a tsunami
hitting New Zealand or Australia will cost billions of dollars as well as tens of thousands
of lives, yet with this risk hanging over us, our public policy around how to manage this
most effectively in local government is very very scarce, so I want to understand why.
So what I’m doing is visiting local government along the southern east coast of the North
Island in New Zealand and using risk modelling as a communication tool which can then inform
them of what the natural hazard risk is, to see whether it will actually better enable
them to develop improved policy for tsunami hazard management. So what I’m finding is that yes, risk modelling
is a useful tool for councils to better understand their natural hazard risk and their tsunami
risk.
