'Living after a disaster' (1/6). Le Monde retraces the paths of major natural disasters and shows how life has gone on in the aftermath, the ongoing stories and lessons learned.

As humanitarian aid poured in, international mediation helped facilitate peace agreements with the Indonesian government.
