News & Events - 2014
CWP professor Ilya Tsvankin (left) and his graduate students Oscar Jarillo Michel and Nishant Kamath (center, right) participated in the 16th International Workshop on Seismic Anisotropy held from November 16-21 in Natal, Brazil. The workshop, organized by the Brazilian Geophysical Society, was the first ever IWSA in Latin America. Ilya was a member of the 16IWSA Technical Program Committee, chaired one of the sessions, and delivered a keynote lecture titled "Orthorhombic symmetry: The new standard model in exploration seismic?".
The CWP group also presented three papers dealing with applications of elastic full-waveform inversion to multicomponent data from anisotropic media. The spectacular oceanfront setting did not distract the participants from engaging in numerous lively discussions, which often continued after the technical sessions. The great tradition of biennial meetings of anisotropists, which goes back to the 1980's, will continue with the 17IWSA in Austin, Texas planned for 2016.
