What good is that?
Would it not be better if you asked questions on how to post including a quote?,  rather than posting nonsensical posts?

2 metre waves across China sea due to Typhoon Ketsana but earthquake warning of waves only barely reaching a foot--------which one are we going to prepare for???????

I dont think i've read such a topic where everybody seems to be at each other's throats.to all you "would be geologists" why not just chill out and maybe concentrate on the humanitarian aspect of the disaster...............geez!

UNFORTUNATELY there has been a second powerful earthquake in last hour in Sumatra 6.9

Your looking for the next one that is a result of enough mass displacement to create a tsunami. Most quakes don't do that. Some do, and as I understand it not necessarily the biggest ones either. So heed the warnings, you only have to go 2 days back to see how deadly serious these warnings should be taken.

[hanssna]

Been living here in the Khao Lak area now for more than 7 years, and yesterday we saw the whole false panic happen again !  Luckily there was no official warning in the area, but it was on the 7 o'clock news ( that a tsunami would be coming, and Bang Muang, Bangsak, and Khao Lak/Bang Niang area should be evacuated ). Me and some Thai friends didn't panic and stuck to the plan we had to drive to the corner of Thap Lumu, and eat seafood ( better go down with a full stomach... ) and saw loads of police directing full pickups of people coming from Thap Lamu area, still a motorcycle accident happened..  One hour later everyone returned, laughing and happy ( no tsunami ) and back to normal again. The family of my friends in Thap Lamu, stayed home anyway, sceptical about it like most people. Let's hope it doesn't really! happen anymore, since we don't believe in it anymore.. numb after 'the real thing'  and so many false warnings.
Anyway, my hart and best wishes are going out to all the people in Sumatra ( and Samoa, earlyer ) who took the sh..t for us again.

Does anyone have any advice?

I am currently a tourist on holiday in Karon Beach.

Our hotel staff laughed at us when we asked them for advice and said that the Tsunami was in Samoa and not here.

Take some single malts and head for the hills just in case. The experts just don't have the practical experience. Just remember the last Tsunami. Good luck brother.

I agree with your post 100% and go to the hill first before anything happens..
My son and I are collecting money to the Phillipines nonprofit and we donate our own to the Red Cross. We urge everyone does his or her part..( any amount will make a difference ) Thanks for posting...my take and opinion.

How did they get the warning teletype? Did they replace the batteries in the early warning system?

Yes, as of several months ago, the Thai gov't couldn't muster up the funds (or ambition) to replace the batteries in the free early warning buoys that were given to them by the US!

no one thought of gel cell pack and a solar panel? ( but then it mite get ripped off)

That would be no good as the bouys and seabed sensor have to be replaced at a max of two years anyway.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE

sending a silly warning out about a day after it happened is worse then useless.
I live in Phuket and any quake with Tsunamis will have got here in a few hours max. The first thing I did was to look at times etc and it was clear there COULDN'T be a Tsunami!
Samoa quake would have to cross Indonesia and Thailand... Likely also the Philippines!
The one in Sumatra could have been here in 2 hours...

Umm Tracer0 did you notice the time I posted that report?  

Just so you can confirm it was 2009-09-30 18:00:00

The report was also compiled well before you posted it farma.
So for tracero to say it was almost a day late is untrue to say the least.

There's a need some basic geography lessons.
How does an earthquake 50km off Padang Sumatra propagate a wave that could come anywhere near the coast of Thailand?

In 2004 the quake reached South America as several oil rigs where going up and down...

Whatever the quake before was a quake but as far as I know some very large blocks fell down into the deep sea....
They spotted during the next few days they were missing! note in 2004!! I think they even had a submarine checking out what happened..

In case anyone is unfamiliar with ZULU time used by NOAA and other agency notices.

Thai Time is ZULU +7 hours

For example the NOAA notice I posted was issued at 1026Z 30 Sep 09 which is 1726 Thai time 30Sep09

I posted as soon as the notice appeared on the NOAA site at 1800 Thai time 30Sep09

The NOAA estimated arrival time in Phuket was 1400Z which was 2100 Thai time 30Sep09 (approximately 3 hours after I posted the notice)

Thankfully it didn’t happen.

Re: We seem to have potentialy 2 tsunamis going in different directions - What happens when they meet ?

In the open ocean, the waves would pass by and be superposed atop each other for the instant that they cross. Tsunami waves in the open ocean are typically only inches high, so maybe you would get a slight blip with a 1 foot wave. If there is any kind of wind blowing, you probably wouldn't even notice it under your boat. But they travel at very high speed, e.g., 500 mph so lots of energy and have very long wavelengths (crest to crest). They start to build vertically when they start to "feel" bottom, which in practical terms, is about on half the wave length. Then they slow down considerably and go vertical. The motion of the water in the wave then also starts to change from circular propagation to back and forth water movements (the ellipsoidal motion of the water/energy propagation is flattened).

Because tsunamis have a very long wave length (can be hundreds of yards or a mile), the start to feel bottom pretty far out from places like Phuket, because it's fairly shallow there. That's why in 2004 you could see it building on the horizon and it actually took a while to get to shore. But all that 500 mph energy is packed into that big mass of water and that's why you see such a huge surge of water at the beach. One other note, tsunamis passing an island will bend around it and hit all sides, and quite often will be higher on the leeward side. So, for instance, a mini tsunami hit Hawaii just a few days ago from that Tonga trench earthquake, and was actually higher on the northeast side for the islands.

Yet another Earthquake in Samoa

SINGAPORE, Oct 2 (Reuters) - A fresh earthquake on Friday rattled the region around the Samoa islands, where a series of tsunamis destroyed villages and killed at least 146.
The U.S. Geological Service reported a 6.3 magnitude quake at a depth of 10 km (6.2 miles) off Tonga, an island near Western and American Samoa islands. There were no immediate reports of damage.

Four powerful tsunamis generated by a huge undersea quake crashed into Samoa and American Samoa on Tuesday, destroying in minutes a paradise of palm trees, resorts and pristine beaches.

Apparently they did not meet.
But as T.I.T.: I believe that they will mate and as usual the male tsunami will pay for it.
