We developed the Aceh Disaster Digital Archive to make information about past disasters more accessible to communities. It employs an open-source data platform, allows free access, and is interactive and easy to use, which is essential for engaging the younger generation. Similar disasters can occur anywhere in the world, and by collecting multimedia data related pre-and post-tsunami Aceh in an alternative medium, we have put it into a visual form and linked it with Social Network Services (SNSs) to facilitate the transfer of information and knowledge about earthquake and tsunami experiences in Aceh to promote sustainable disaster mitigation. Information is the most important issue in Disaster Risk Reduction (DRR). Information transfer and dissemination is needed, sustainability from generation to generation. Indian Ocean tsunami in 2004 was occure in Aceh. The tsunami was estimated to cause more than 200,000 dead. One of the big reasons is GAP information from the past disaster. Today, information could be delivered and spread up to the world as soon as possible by internet. In this millennium era, used historical digital archive and display in open data source by github platform is one of solution to fill in the GAP information for Disaster Risk Reduction and global information. The Aceh Disaster Digital Archive will remind people around the world that local knowledge from past disasters offers invaluable lessons for disaster risk reduction and global information.
