In December 2012, Jeroen Tromp of Princeton University, visited the US Department of Energy’s Oak Ridge Leadership Computing Facility. Tromp came to the OLCF with an ambitious proposal for imaging the planet in a new way that brought together massive earthquake datasets, advanced numerical algorithms, and modern high-performance computing to produce high-resolution, 3D images of the entire globe—from the surface to the core-mantle boundary.
<p>In 2019, Tromp’s team completed its second-generation 3D model of the Earth’s interior, called GLAD-M25. The new model draws from the seismic data generated by nearly 1,500 earthquakes—a sixfold increase from the team’s first-generation model—to capture smaller-scale features within the Earth’s subduction zones, plumes, and massive hot spots.
