[Slide : Text/Image] [Daniel Jaksa, Geoscience Australia Co-Director,
Joint Australian Tsunami Warning Centre] To Australia's Northwest and East there's
eight thousand kilometres of very active tectonic plate boundaries. In fact one third of all
the world's earthquakes... [Slide : Text]
...occur along these boundaries, making the... [Slide : Animation of map and earthquakes/tsunamis]
...most likely source of tsunamis that could impact Australia. They're capable of generating
a tsunami that could reach the mainland in two to four hours.
[Daniel Jaksa] Northwest Australia has had more tsunami events
than any other region in Australia, and they were caused by earthquakes off the coast of
Indonesia. However there aren't many people in the area so the risk...
[Slide : Text] ...of a disaster is relatively low. The East
coast of Australia is... [Slide : Animation of map and earthquakes/tsunamis]
...susceptible to tsunamis created by earthquakes in the Kermadec or Puysegur trenches which
are to the North and South of New Zealand. If an earthquake is strong enough, Lord Howe
and Norfolk Islands, as well as parts of the highly populated Eastern...
[Daniel Jaksa] ...seaboard of Australia may be inundated
by tsunami waves. Other coastal areas could also experience
the dangerous rips and currents of a marine tsunami. This scenario presents a higher disaster
risk for Australia than a tsunami in the northwest of Australia.
The Joint Australian Tsunami Warning Centre... [Website address shown across screen]
...is the authority for tsunami warnings in Australia. If there's a tsunami, we issue
advice and warnings to the Australian public. [Slide : Text and image]
