Jeroen Tromp, Professor of Geosciences and Applied and Computational Mathematics, invited to make a presentation at the October 27th President's Lecture Series (details below):
Earthquakes, Impacts and Seismic Imaging
Seismologists use information contained in seismic waves to "map" Earth's interior. Such waves are generated by a variety of sources, including earthquakes, impact events, and man-made devices. This presentation considers two 2011 earthquakes, namely the March 11 Tohoku and the August 23 Virginia earthquakes. The talk also investigates the seismic consequences of a hypothetical collision of a large meteorite, asteroid or comet with Earth, in particular in the vicinity of the antipode. Specifically, proposed linkages between the Chicxulub impact 65 million years ago and Deccan Traps antipodal volcanism are investigated. Finally, the talk explores how seismologists use differences between observed and simulated records of seismic wave propagation ---so-called "seismograms"--- to image the subsurface, culminating in a seismological tour of the European upper mantle.

About the lecture series:
The President's Lecture Series was established by President Shirley M. Tilghman in the fall of 2001 to give Princetons faculty an opportunity to learn about the work of their colleagues in other disciplines and to share their research with the University community.
