Hi all
Good morning to you all.
i've read in a scientific paper that, the 2nd wave of the tsunami is more destructive in indian ocean, where as 3 rd wave in the pacific ocean. why it is so?
can anyone clarify my doubt...
thanks in advance.
have a gr8 day.

Could you please provide a link or reference to the paper you read so I can read it too?

"Numerical modelling concepts for tsunami warning systems"
- T.S.Murty, A.D.Rao, N.Nirupama & I.Nistor

in this paper you can see that which wave is the highest in tsunami waves.

Hi Nanda! Thanks for the link.

Okay. I skimmed through this article. There seem to be some inconsistencies, and there are a couple of things I have to question, such as there are no highly populated areas on the Pacific Ocean coastline. I thought for certain there were many....hmm..

This article starts off by stating the Pacific Ocean has both local and trans-oceanic tsunami waves. However, through most of the remaining report there is very little reference to local events in the Pacific Ocean.

I did find a page that stated the 3rd to 5th wave usually has the highest amplitude. I am unable to find the section that specifically states tsunami amplitude in the Indian Ocean is strongest during the 2nd wave. Could you give me a specific page number?

I have a strong understanding of how different tsunami waves have different characteristics based upon the distance they travel, different slopes in the land the run upon, and nature's protectors such as coral reefs, forests, and some manmade structures. If the tide is in or out can also have an affect. There are many different things which affect tsunami waves.

This article seems somewhat biased toward independent tsunami warning systems. I see no reason why a country could not initiate it's own warning system if it wanted to do so. It is certain no two tsunamis are going to be identical.

It is certain the force generated by the earthquake, landslide, volcanoe, or meteorite will have a determining affect on the severity of the tsunami waves. Each movement is unique, and generates different strength in force.

My brother lives on a island in the Atlantic Ocean where a tsunami wave crossed completely over it. The people ran to shelter in the caves in the mountains. Many people did not make it. The ones who did remember looking out of the caves to see water completely over them. Truly a horrifying experience and one that will always be remembered.

Let me know which page that "2nd wave" amplitude in the Indian ocean is on, and I will look at it again more closely.

Dear Cynthia,
Thank you very much for your kind reply.
i'm a beginner in the field of "understanding the propagation of tsunami waves".
so i would like to hear more from you, regarding numerical analysis and methods of wave propagation. if u could provide me some links or some docs for the same, i'll be very thankful to you.

Then regarding that page no. which u've asked me... it is in page no.1074, (second paper of the article), it is mentioned in a table "Tsunami characteristics of the four oceans", the parameter is "which wave is the highest".

With Best Regards
Nanda

Yes. The second wave statement was there in the chart. Thanks Nanda!

There is some information in the report which may need further study by the scientists presenting the report as there do seem to be some inconsistencies. You will have to email them and ask them to explain some of the things they present because they are leaving out quite a bit of additional information in this report.

Here is a link which anyone can read and understand with more actual scientific information than most and which provides supporting evidence which may help you out some Nanda. There are some great links down at the bottom of the the site as well.
