why in kerala coast the tsunami is least affected in the area of alappuzha where as the strength of it was very high in the north and south of this region. many of unprotected (by sea wall) area was not affected much. where there was only a mere rise and fall of sea level. is there any scientific explanation available?

Let us hope someone who is looking into the Kerala coastal region
will reply to this post.

Meanwhile, here is an image of the Tsunami affected regions of
Kerala, provided by CESS at http://www.cessind.org/Tsunami.htm

This was the reply to Oceanographers Net from Prof. A. N. Balchand,
Dept of Physical Oceanography, CUSAT, Kerala:

The diffracted wave off Sri Lanka had crests coinciding Kollam and Natika
whereas around Alapuzha the trough worked its way around.

In fact, in Kerala, the impact (2m height or so, some say 4m) is hardly
comparable to any normal type of Tsunami !!

We invited CESS [Center for Earth Science Studies], Thiruvananthapuram to
provide some info regarding the impact on Kerala coast and an explanation to
the above image, waiting for their response :)
