GPR2020 meeting
by Dominique ROUSSET 07 Feb '20

07 Feb '20

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. -- |Dominique Rousset LFCR UMR5150 / E2S UPPA / Dpt des géosciences| |Univ.

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.

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.

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.
