Jeroen Tromp

About

Jeroen Tromp is the Blair Professor of Geology, Professor of Geosciences, and Applied and Computational Mathematics at Princeton University. He joined the Department of Geosciences in July 2008, coming from the California Institute of Technology, where he served as the Director of the Seismological Laboratory and was the McMillan Professor of Geophysics. Tromp's academic background includes a Ph.D. (1992) and an M.S. (1990) in Geophysics from Princeton University, and a B.Sc. (1988) in Geophysics from the University of Utrecht in the Netherlands, his native country. His previous academic appointments include a faculty position at Harvard University from 1992 to 2000. His primary research areas are in Theoretical & Computational Seismology, with topics including surface waves, free oscillations, body waves, seismic tomography, numerical simulations of 3-D wave propagation, and seismic hazard assessment. Tromp has contributed to the field through his work on seismic wave modeling and analysis, and in collaboration with the late Princeton Geosciences faculty member Tony Dahlen, he published the book 'Theoretical Global Seismology.' He also serves as the Director of the Princeton Institute for Computational Science and Engineering (PICSciE). His research aims to advance understanding of Earth's interior through computational seismology techniques.

• Constraints on the shallow elastic and anelastic structure of Mars from InSight seismic data

  Nature Geoscience · 2020 · 305 citations

  Mars’s seismic activity and noise have been monitored since January 2019 by the seismometer of the InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander. At night, Mars is extremely quiet; seismic noise is about 500 times lower than Earth’s microseismic noise at periods between 4 s and 30 s. The recorded seismic noise increases during the day due to ground deformations induced by convective atmospheric vortices and ground-transferred wind-generated lander…

• Global adjoint tomography—model GLAD-M25

  Geophysical Journal International · 2020 · 224 citations

  SUMMARY Building on global adjoint tomography model GLAD-M15, we present transversely isotropic global model GLAD-M25, which is the result of 10 quasi-Newton tomographic iterations with an earthquake database consisting of 1480 events in the magnitude range 5.5 ≤ Mw ≤ 7.2, an almost sixfold increase over the first-generation model. We calculated fully 3-D synthetic seismograms with a shortest period of 17 s based on a GPU-accelerated spectral-element wave propagation solver which accommodates ef…

• GLAD-M35: a joint P and S global tomographic model with uncertainty quantification

  Geophysical Journal International · 2024-08-05 · 41 citations

  articleOpen access

  SUMMARY We present our third and final generation joint P and S global adjoint tomography (GLAD) model, GLAD-M35, and quantify its uncertainty based on a low-rank approximation of the inverse Hessian. Starting from our second-generation model, GLAD-M25, we added 680 new earthquakes to the database for a total of 2160 events. New P-wave categories are included to compensate for the imbalance between P- and S-wave measurements, and we enhanced the window selection algorithm to include more major-a…

• The origin of secondary microseism Love waves

  Proceedings of the National Academy of Sciences · 2020 · 40 citations

  Senior authorCorresponding

  The interaction of ocean surface waves produces pressure fluctuations at the seafloor capable of generating seismic waves in the solid Earth. The accepted mechanism satisfactorily explains secondary microseisms of the Rayleigh type, but it does not justify the presence of transversely polarized Love waves, nevertheless widely observed. An explanation for two-thirds of the worldwide ambient wave field has been wanting for over a century. Using numerical simulations of global-scale seismic wave pr…
