Yep yep yep...If a tsunami / storm surge comes anywhere near my place the rest of you blokes are in a whole lot of trouble.

If it gets that high..most of SE QLD will get top dressed with Stradbroke and Moreton Islands.

It is very difficult to predict the nature of a tsunami simply by the magnitude of an under sea quake. It is what happens to the ocean floor - ie a fracture and degree of subsidance or lift in the crust that displaces the water and creates the wave. The effect of the Sumatran quake on tsunami generation wasn't fully understood until the sea floor was surveyed and seizmic data collated after the fact. This event was huge with a rupture in the sea floor of over 1000kms long.

Here is an animation (from the US geological survey) of the tsunami generation as the ocean floor "unzipped" at over 2km/second. Its a 9mb download so may take a little while.

Have just been bush for a week with no mobile coverage. Last sunday, on the day of the warning, we were game fishing off the rocks in southern NSW and had no idea of the warning.

We always keep a look out for a bigger swell and I remember telling my mate to keep a watchout..Just thinking what could've happened if it did hit............

I read this post with intrigue. I am also loathe to get on my high-horse and preach, however some threads here bring a thousand questions to mine. Firstly, I am a current surf lifesaving club president, with over 30 years active service. Included in those years is many hours in various rescue water craft. As well, I have performed many, many beach patrol rescues and have had to cope with 9 fatalities over those years. All of those will go with me to my grave. I would like to set the scene from my point of view.
Saturday night at approximately 9:00pm I receive 3 phone calls, 2 texts and an email from various local rescue authorities and surf lifesaving with regards to the Tsunami the following morning. They all basically relate to what procedures should happen in the morning. They all make perfectly good sense to me. The following morning I join our beach patrol to ensure we are all following correct procedure, part of which is the closure of the beach. It amazed me to find people completely ignore us and going for a swim. Even people with young children on boogie boards. Tsunami aside, conditions were just plain dangerous due to extreme high tide, large swell and irregular rips and currents. We were not Nazi's or overbearing, yet people still treated us with contempt. Freedom of choice does not come into it. If you walk on a job site that is a hard hat area, you put on a hat hard. Simple as that. People have to realise the beach is the lifesavers job site. We are not there to intimidate or treat people with contempt. People need to realise a million preventative actions is better then 1 rescue. It's as simple as that.
3 weeks earlier I performed a rescue on an overturned boat on one of our local bars. The swell was large, tide was low and pressure waves were everywhere. People were advised not to cross bars. The outcome was a rescue of 3 people, a severely damged 70K boat with only 30 hours on it and one very rueful skipper. I have one question here, WHY???? Freedom of choice you say. Warnings and preventative actions are put in place for our safety, like a hard hat. You may not need them, and at times they may seem overkill. However one day they might just save your life.

I got up at 2.30am on Sunday and saw the alert. I thought that the smart thing to do would be to give the trip a miss. I was more concerned about the car left at the ramp on a king tide high than about surviving a tidal surge in the Bay though.
I fully support the decision of BOM to provide the warning. It was my choice to be cautious and I would probably do the same thing if it happens again.
As for the Lifesavers closing the beaches I have a pretty low opinion of the guys knocking them. They put in a lot of hours to try and protect fools against themselves. Most rescues are of people who did not understand the potential danger in what they were doing and thought they new better. If they are given a warning whether it be shark or tsunami they would be negligent to ignore it.
The effects of tsunami on coastlines are just beginning to be understood and a few hundred kms can make all the differance so Hawai missing out does not mean we are in the clear

cannot believe all the people on the gold coast who took a blanket down and literally sat on the beach to get a good view of the tsunami
