Carissimi Soci SGI,
Carissimi Soci Società Associate,
su indicazione del Prof. Fabio Trippetta (Sapienza, Università di Roma), vi segnaliamo il seminario intitolato "Advances in Global Seismic Tomography With applications in Geodynamics and Mineral Physics", tenuto dal Prof. Jeroen Tromp (Princeton University). Il seminario si terrà venerdì 20 gennaio alle ore 11 in Aula Lucchesi, presso il Dipartimento di Scienze della Terra dell'Università di Roma La Sapienza.
Per ulteriori informazioni si rimanda alla locandina e all'abstract dell'evento.
Cordiali saluti,

Advances in Global Seismic Tomography
With applications in Geodynamics and Mineral Physics
The concept of imaging Earth's interior based on the full physics of seismic wave propagation was introduced approximately 35 years ago. Thanks to modern numerical methods and high-performance computers, seismic Full Waveform Inversion (FWI) has finally come to fruition in the past decade. Today, FWI is used across nine orders of frequency and wavelength, from megahertz frequencies and millimeter wavelengths in ultrasound medical imaging and nondestructive testing to millihertz frequencies and thousand-kilometer wavelengths in global seismology. The goal of FWI is to use every wiggle in a seismogram to understand the underlying physics. In this talk I give an overview of the status of global seismic waveform tomography, with applications to problems in geodynamics and mineral physics.
