WebFeb 9, 2024 · The analysis shows that the focal mechanisms of the foreshock sequence of the Yangbi earthquake are highly consistent and are all of the strike-slip type; the focal mechanisms of the... WebThe HASH f77 subroutines use fixed dimension arrays for efficiency. These array dimensions must be known at compile time, and hence when this module is installed. The dimensions must also be shared with the python side in order to ensure the numpy arrays are correctly sized to match their fortran counterparts. The relevant parameters are:

Web5 There are two additional control parameters: dang, which specifies the resolution of the focal mechanism grid search, and maxout, which gives the maximum desired number of acceptable focal mechanisms output. The total number of acceptable mechanisms found is given by nf (but a maximum of maxout are returned.)
