A Seismic Mapping Milestone: Princeton-led Team Produces 3-D Map of Earth’s Interior

We have come across some encouraging news in the field of seismic mapping:

Using advanced modeling and simulation, seismic data generated by earthquakes, and one of the world’s fastest supercomputers, a team led by Jeroen Tromp of Princeton University is creating a detailed 3-D picture of Earth’s interior. Currently, the team is focused on imaging the entire globe from the surface to the core–mantle boundary, a depth of 1,800 miles.

According to Ebru Bozdag, a co-principal investigator of the project and an assistant professor of geophysics at the University of Nice Sophia Antipolis, “That’s a milestone for the seismology community. For the first time, we showed people the value and feasibility of running these kinds of tools for global seismic imaging.” (Cited in Oak Ridge National Laboratory News)

Such progress is of great interest not only form seismologists’ point of view but also in the context of risk communication. Providing people with visual information of the actual processes underneath them could be of value in the preparation phase of geophysical disasters.
