What If People Were Complacent About Tsunamis?
What If People Were Complacent About Tsunamis?
Australian Expert Asks

A visiting Australian expert will
give a public lecture at the University of Canterbury (UC)
next week about the threat of tsunamis.
Professor
James Goff of the University of New South Wales in Sydney is
a visiting Erskine lecturer at UC and will talk about
tsunamis at his lecture next Wednesday (May 8). The Erskine
fellowship programme was established in 1963 following a
generous bequest left by former distinguished UC student
John Erskine.
Professor Goff says local and
regional authorities are still only just waking up to the
fact that their coastlines are exposed but they don't really
know how bad things could be when a tsunami hits New
Zealand’s shores.
``Eighty-five percent of all
historically documented tsunamis have occurred in the
Pacific region and while scientists are still pretty much
scratching the surface when it comes to understanding how
bad these events have been over the past few thousand years,
New Zealand is well ahead of the game and has one of the
most comprehensive geological records of tsunamis in the
world.
``Once you start looking back over the past
few thousand years, the greatest number of tsunamis found at
any one site in New Zealand is on the West Coast, not the
east coast as most people suspect,’’ Professor Goff
says.
In the lecture, he will ask if it is true
that the Japanese were unprepared for the 2011 tsunami and
what does New Zealand ignore at its
peril?
``Tsunamis can be catastrophic and events
such as the recent Tohoku-oki disaster in Japan show us just
how bad they can be.
``However, all is not lost
because many researchers are now producing detailed tsunami
hazard assessments that are there to help manage such
events. The important thing though is to know how good those
assessments really are – we do not want to be lulled into
a false sense of security, but equally we do not want to hit
the panic button.
``My focus is primarily to wake
up a few more people to the tsunami hazard in New Zealand.
Since the relatively minor 2010 Chile earthquake that sent
New Zealand a long distance tsunami, some local and regional
authorities have been waking up to how bad things could be.
``We need to seriously understand the nature of
the tsunami hazard for New Zealand's coast. We don't know
when they are going to happen, but we do know that they will
- so let's know as much as we can about the nature of this
beast,’’ Professor Goff says.
