Finite Difference Travel-Time Computation
10:00 AM-12:00 PM
Room: Ballroom B
Finite difference travel-time computation is now a well-established
tool in applied geophysics. Until recently, these algorithms were
limited to isotropic wave modes and first arrivals, for excellent
theoretical reasons. Recent advances have begun to chip away at these
limitations, as the speakers in this session will show.
