[Metin Kahraman]

Dear all;

I am Metin Kahraman and I am a new user of SW4. I am trying to model  
17 August 1999 Izmit Earthquake using sw4. I compiled SW4 successfully  
and trying first runs.

I have Vs30 file for the Izmit region, I am trying to put this input  
SW4 to give more detailed surface info to SW4. but I could not see  
anyway to add this information into SW4 input file.

Is anyboy know how to this in SW4?

Best wishes

Metin
