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.
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.
I just created a new version of RISK. The list of changes is short and includes some new features related to the new database – seismic catalog – used in Rudna Copper mine in Poland:
- Additional columns for seismic activity, cumulated seismic activity and seismic activity in zones plots.
- Corrections to plotting routines
- Updated graph editor
