GDACS is a cooperation framework under the United Nations umbrella, established in 2004. GDACS aims at filling the information and coordination gap in the first phase after major disasters.
It provides real-time access to web‐based disaster information systems and related coordination tools. GDACS is managed by a Steering Committee, currently chaired by the EC Monitoring and Information Center (MIC) in DG Humanitarian Aid & Civil Protection.
The Emergency Relief Coordination Centre (ERCC) in the United Nations Office for Coordination of Humanitarian Affairs (OCHA) in Geneva acts as GDACS Secretariat.
GDACS provides alerts and impact estimations after major disasters through a multi-hazard disaster impact assessment service managed by the EC-JRC. It provides maps and detailed information on earthquakes, floods, cyclones and volcanic eruptions.
Users include governments and disaster response organisations.
