Welcome!

Here are many free source-codes, (Windows) executables, utility programs,
and data files for tectonophysicists, regional geologists, and/or
seismologists to review and (possibly) use in their own research.
Most programs could be recompiled to work under other operating systems.

    (N.B. The name /oldFTP/ just means that this folder replaces
     the former FTP server that used to have the URL of 
                ftp://element.ess.ucla.edu
     It does NOT mean that all the contents are "old".
     Actually, this folder is frequently updated with new programs.)

----====== HERE IS A BRIEF, HIGH-LEVEL GUIDE TO THE CONTENTS =======----

I. MOTION & DEFORMATION OF TECTONIC PLATES OF LITHOSPHERE

     A. KINEMATIC MODELS (accurate velocities, but little/no physics)

          1. Neotectonic models (present and/or Quaternary)

               (i) Rigid-plate models 

                    Euler's-law utility: /oldFTP/OMEGAxR/
 
                    Model PB2002: /oldFTP/PB2002/

              (ii) Deforming-orogen models: 
 
                    Analyze geologic slip-rates: /oldFTP/Slippery/

                    Fit velocity field to data: /oldFTP/NeoKinema/

          2. Paleotectonic models (pre-Quaternary)
