Plane Fitting
The Plane Fitting App provides a tool for fitting a plane through selected seismic events. The app performs principal component analysis (PCA) on the spatial data provided and generates a plane normal to the minor axis with the extent determined by the major and intermediate axis. A stereonet is provided showing the pole of the plane from the PCA. Planes are also fitted through three-event combinations of the selected events. The pole distribution of these planes is shown as contours on the stereonet. A goodness of fit analysis is performed and a simplified ranking assigned to the best-fit plane.
Key Features
- The plane can be exported as a
*.pntfile for later re-use in a 'distance to' filter or for display in other apps and programs.
