The Sahana Software Foundation has deployed an instance of the Sahana Open Source Disaster Management Software server to provide a flexible solution for organizations and communities to respond to the Nepal Earthquake:

Please contact sahana-nepal-response@sahanafoundation.org with questions or to request  support or additional features.  If you want or plan to use our software please provide some details about your organization and your specific needs. The Sahana community has also been working with the Ministry of Home Affairs National Emergency Operation Center (NEOC) to support their deployment of Sahana. We hope that this will become a platform to share data that is being captured and curated by the Digital Humanitarian Network. We are also coordinating with IBM and the United Nations Development Program (UNDP) who are providing support to the NEOC. If you would like to support us you can volunteer by sending a message to  sahana-nepal-response@sahanafoundation.org and / or donate here.
