Focal Mechanism Determination from S Wave Observations of Different Qualit
, 1970 A least squares method is derived for the focal mechanism determination from S wave observations (polarization angles) of different quality. Some considerations are made on how to determine a weight appropriate to each observation.As one of numerical ...

FocoNet: Transformer‐Based Focal‐Mechanism Determination
Journal of Geophysical Research: Machine Learning and ComputationTraditional focal‐mechanism determination primarily relies on fitting the first‐motion polarities with grid‐search algorithms. We developed a machine‐learning model, FocoNet, to include more seismic information into focal mechanism determination.
