    • Implications of 3D Seismic Raytracing on Focal Mechanism Determination 

      Newrkla, Katharina; Shiddiqi, Hasbi Ash; Jerkins, Annie; Keers, Henk; Ottemöller, Lars (Journal article; Peer reviewed, 2019)
      The purpose of this study is to investigate apparent first‐motion polarities mismatch at teleseismic distances in the determination of focal mechanism. We implement and compare four seismic raytracing algorithms to compute ...
