Video-download: Calculated distribution of heat flow at the core-mantle boundary (WMV)

The animation shows the calculated current distribution of heat flow at the core-mantle boundary. The heat flow beneath subduction zones of the last 300 million years exceeds the heat flux below areas where no subduction occurred many times over.
