US: A volcanologist with Geological Society of America, Dr. Ian Saginor, is using 3D printing to prepare people for volcanic eruptions. Through his Volcano Terrain Project, Saginor creating miniature scale models of regions that are at risk. This initiative is more effective than 2D maps and 3D digital images, because it includes detailed topography of the region. The model also shows the route and flow of ash and lava. Saginor says that two-dimensional hazard maps can show people where the danger is, but a 3D printed model can show them why.
