The VDC is a public, web-based search engine for accessing worldwide earthquake strong ground motion data. While the primary focus of the VDC is on data of engineering interest, it is also an interactive resource for scientific research and government and emergency response professionals.
VDC is restricted to
strong-motion data, principally from earthquakes of magnitude 5.0 or larger in earthquake prone areas and 4.5 or larger in other areas. - The VDC was incorporated as a part of the Center for Engineering Strong Motion Data (CESMD) in 2012.
