Hi all,
We are probably quite a few people using SU for GPR processing.
What do you think of a common (probably poster) presentation of SU and
GPR at the next world GPR meeting in... Boulder, Colorado, at the CSM,
the birth place of SU ?
It would not be a big scientific achievement but may be a way to enlarge
our community. By the way many people in the GPR community have other
background that geophysics and don't know the basics of seismic
processing and imaging.
The author would be « Seismic Unix user group » or something like that...
Quick answer (or moral support) is needed. A short abstract must be
issued in the next days.
The conference WWW site : https://gpr2020.csmspace.com/
Have a nice day !
D.

Hello Dominique:
Hmm, that’s odd. Of the few Demos I looked at last night, the models were anisotropic and I could see the surface waves on the images. I haven’t had time to dig into the scripts that generated these Demos so I can’t give you more details.
Best regards,
Jim Gaiser

Hi,
no.
it's acoustic and you need S waves to generate surface waves...

Hello Paul:
Do the scripts and codes in “./src/demos/Synthetic/Finite_Difference” model surface waves? I haven’t checked.

Subject: [Seisunix] Surface wave modeling in seismic unix
Hello colleagues.
In Seismic Unix, there are packages for elastic modeling (trielas, suea2df). I would like to know if there is a way to model surface waves (or ground roll) in seismic UNIX. Or do you know some other package free-open source?
thanks very much.
Sincerely,
Paul Goyes

Paul:
I am new to this SU mailing list so I am not sure you are getting my responses.
Look at the demos in “cwp/src/demos/Synthetic/Finite_Difference/Suea2df”, specifically Demo3. It creates a Rayleigh wave because the source sz is only 20. I know nothing about the accuracy or limitations of this code but It is a place to start.
Hope this helps,
Jim Gaiser
