Welcome!

Here are many free: F-E source-codes; executables (for Windows, with
choice of 32-bit or 64-bit, and sequential or parallel); utility programs;
mapping programs; seismicity forecasts and associated scoring programs;
and data files for tectonophysicists, regional geologists, and/or
seismologists to review and (perhaps) use in their own research.
Most programs could be recompiled to work under other operating systems,
because in most cases they use only an ASCII-text user inferface.

    (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 & revised programs.)

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