Hi Roger:

It does to the extent that one can get a general idea which direction the waves are coming from. I'm trying to figure out how to make it an exact science, say at point "A" on a given fault, what direction are the waves coming from? Knowing this, and the orientation of the fault at a given point, one could calculate an 'angle of attack' from 0 to 90 degrees. It's probably just math, and I think I have the formula somewhere .... it would be neat to assign an orientation for fault segments into a database and when a large EQ occurs, compare the incoming waves against each fault segment, to figure out which are most at risk....
