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.

SRL paper on hybridMT package

Finally, the paper on hybridMT MATLAB/shell environment package for seismic moment tensor inversion and refinement is out! The paper, published in Seismological Research Letters – Electronic Seismologist is freely available for download:

hybridMT/fociMT package

Two pages dedicated to fociMT/hybridMT moment tensor inversion and refinement library are published on my website: https://www.induced.pl/hybridmt

Page dedicated to RPGEN routine

I added a page dedicated to rpgen.m routine. RPGEN.m calculates P-wave, S-wave, SH-wave and SV-wave radiation pattern using shear-tensile source model. Original, it is a part of my paper “Assessment of P and S wave energy radiated from very small shear-tensile seismic events in a deep South African mine” published in Journal of Geophysical Research.

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.
