Australians are well versed in the homegrown natural hazards that we encounter every year, from bushfires in summer to storms in winter, cyclones up north and flooding along our rivers. But we don’t often stop to consider the threat posed by tsunamis. Should we?................................. theconversation.com/making-waves-the-tsunami-risk-in-australia-60623 |

Should we?................................. theconversation.com/making-waves-the-tsunami-risk-in-australia-60623"Australia is a lucky country when it comes to tsunamis and we’re highly unlikely to see an event like what occurred in Japan in 2011 on our shores. But that doesn’t mean that we’re immune to tsunamis and further research will provide the evidence we need to be prepared." Very interesting and well written article. This might be the case but there is still significant risk - which is a real pain as the many islands that Australia has are excellent bug out locations, like Kangaroo island and a few other choice places that I have considered. The risk is simply to high as the earth is getting more geotechnically unstable. |

I remember either reading, or hearing, that Adelaide would be quite safe from a tsunami as KI would take most of the brunt of it. I'll look into it and see if this was fact or hearsay! |

If you want to scare yourself regarding big waves ... have a read of this published paper (http://www.geosci.usyd.edu.au/users/prey/Teaching/Geos-2111GIS/Tsunami/PirajnoMine04-Fortescue.pdf) The 100+ metre event mentioned (bottom 4th pg and event 5 in appendix) only happened about 9000 years ago. So ... bad Tsunami ju-ju around Jervis Bay! Infact, the data in appendix A consists overwhelmingly of NSW events. Even though my home here in SA is only a few metres above sea level I never give big waves a second thought. On a tangent ... I've worked out that if global warming sea level rise estimates (6m) are true ... my place will become water-front. Happy days ... |
