23. Fault plane solution

SEISAN includes five programs for estimating the fault plane solution, FOCMEC, FPFIT, HASH (called hash_seisan),EBEL and PINV. The programs are described below, they can all be called from EEV. Fault plane solutions can be plotted with EPIMAP (new from version 9.0), W_EMAP (Windows only) and FOC (see below).
Apart from MULPLT, polarities and amplitude ratios can be read in a more efficient way with the programs PLOTPOLARITY, AUTORATIO and PLOTRATIO.
The program GMTNOR also makes output which can be used with GMT. In EEV fault plane solutions can be added manually to an event with commands inputfps or ifp.
