Dear Prof. RNI,
I congratulate you on this second of the series (the first one being that of
Delhi). However, engineers may like to have results in a readymade form for
them to use in practice. I do not know how many Sefians would have read both
your papers but atleast I hope they would visit the site
http://earthquake.usgs.gov/research/hazmaps/design/index.php atleast ONCE to
see what the type of excellant research you are doing that may lead to that
goal.
The IS Code is quite backward - sticking to few broad zones when long ago
other codes had switched over to acceleration maps. I hope one day, even in
my own lifetime, we will enable building engineers with that type of
information available in that web link.
We need to take up this in MISSION MODE by dedicated persons in IISc and
IIT's and  researchers in other Institutions to accomplish it in say 18
months from now. May be NICEE could coordinate this project.
Sincerely
ARC
PS: I will be sending a separate mail to your personal ID after rereading
your paper.

Dear Prof.ARC: Thanks for your kind words. Researchers should continuously
try to upgrade the knowlewdge base of the community. This is too well
known. But as the country is rushing towards 'knowledge as power', civil
engineering profession, in some areas, continues to be embarassingly
backward. Estimating seismic hazard and presenting it to design engineers
is one such. Not that the learned in EE are not aware of this. But, then
their loyalty seems to be more to money and consultancy, with what little
know how is available, rather than spend time on hard research, leading to
verifiable and reviewable public documents. Many are also afraid of public
debate which is very essential in a democratic set up like ours. Under the
pretext of India being a developing country, earthquake engineering had
been denied progress by vested intersts. Now that we are discussing these
openly is a sign that those days are over for good! It is definitely
possible to come out with an acceleration map with differing
probabilities, for the whole country. If only I can get the support of
say, four young engineers with good computational abilities (MATLAB etc),
the map can be prepared with whatever is known about the tectonic
situation of the country. Naturally this will have to be in an upgradable
mode so that revisions are possible with minimum further effort. About
making my research understandable to designers I am available at their
service, as always I have been.
