Fault Plane Solutions

Fault Plane Solutions#

This module allows for the display of fault plane solutions as beachball plots. The beachball plots can be exported to shapefiles. Note that two shapefiles are exported - one for the actual beachballs and one for a boundary of the beachballs.

The core code is translated from bb.m written by Andy Michael and Oliver Boyd at http://www.ceri.memphis.edu/people/olboyd/Software/Software.html

Options are:

  1. FPS Algorithm – Can be FOCMEC (focal mechanism) or FPFIT (double-couple FPS, Reasenberg and Oppenheimer, 1985).

  2. Width scale factor – Option to scale the “beachballs”

  3. Geographic units or Projected units. – Select based on input data.

  4. Save Shapefile – Export the beachballs to shapefiles.
