Update 3.8.1 to foci software package

New version (3.8.1) of foci software package has been released recent week. This version brings some new features that will be developed in next months:

– Introduction of inelastic attenuation correction in calculation of full seismic moment tensor.
– Multiple corrections to preferences window.
– Introduction of foci package into github version control system
– Code cleanup.

The polish version of foci website has been also rearranged and refurbished. This is the first step to translate this page into english.

Radiation pattern of shear-tensile faults on Matlab File Exchange

While writing a paper to Journal of Geophysical Research on S-to-P radiated energy ratio from shear-tensile events I created a number of MATLAB functions related to the methodology presented inside. One of the routines, rpgen.m, I just uploaded to MATLAB file exchange. This function calculates P, S, SH and SV radiation pattern from shear-tensile fault at certain takeoff angle and azimuth of observation. The fault itself is parameterized by strike, dip, rake, tensile angle and Poisson’s ratio.
