Hi Simon,
IARU Region 3 may have information you can use that is specific to the local area.
Their web page for disaster communications is here:
http://www.iaru-r3.org/dcom/r3dcom.htmYou might browse around the site and see if you can find direct contacts - the site
hasn't always been kept up to date. There should be a lot of information about
the earthquake in Japan and the tsunami in Indonesia that you can use, and they
also would know the local organizations and conditions.
The IARU R3 newsletters are here:
http://www.iaru-r3.org/news/r3n.htm#newsletterand they appear to contain a number of examples of disaster communications.
My recommendation would be to find who is the R3 Disaster Coordinator (or whatever
title they have) and contact them directly for further information.
(And the other IARU Regions have similar sites if you don't find what you need.)
