The Swanker welcomes the planned tsunami early warning system as a way to prevent loss of life, although he sees some hazards emerging from the reconstruction effort:

Initial infrastructure costs are estimated at around US$120 million,
with almost half of the funds coming from Germany.  A small investment
for long-term peace of mind to help ensure that a humanitarian disaster
of the magnitude of December 26 will never again break on Indonesian
shores.
Unfortunately, there seems to be less foresight in the sourcing of materials to rebuild homes for Acehnese survivors:

The timber for the new houses is being logged illegally in the mist-shrouded mountains rising in the distance.

I wrote about this a few weeks ago.
Less than two years ago, some 200 people died when a landslide and
flashflooding struck the famous orang utan resort of Bukit Lawang,
situated in the highlands of Gunung Leuser National Park on the border
between Aceh and North Sumatra provinces.  Rampant deforestation of the
hillsides was blamed as the prime culprit.
