VDAP brings nations together in scientific collaboration to address common problems. In doing so, the program builds international partnerships and enhances relations between the United States and other nations.
Both crisis response and capacity building are fundamental components of VDAP. During a crisis, affected countries may request VDAP assistance either on-the-ground or remotely. Depending on the situation, VDAP will supply satellite data, donate monitoring equipment and provide many more support functions. The program also trains counterparts and helps countries establish and/or enhance their own technical and intellectual capability to prepare in advance and manage future volcano crises. Additionally, VDAP supports infrastructure development, such as installing scientific instruments and monitoring networks.
