Dear SPECFEM2D developers and users,
I would like to ask for your help on how to make a proper approximation on
a station using a moment tensor as a source.
I ve gone through the manual and the relative papers describing the problem
but I got a little bit confused.
So if I have for example a Strike 322, Dip 40, Rake -72 foc mec
then I get
Mxx Myy Mzz Mxy Mxz Myz :
0.54774 0.38886 -0.93661 0.50245 -0.28821 0.01560
If I use only Mxx Mzz Mxz its fine for the stations at distances bigger
than the dimensions of the rapture. BUT only for the stations with 90deg
azimuth.
In practice, how can I get the correct Mxx Mzz Mxz at a station with a
different azimuth? Lets say 60 deg.
Can you please provide an example on that? I am interested for P waves for
now
Thank you in advance, your help means a lot
