Hi all,

  I could not resist sending the volume file "030925.200040.oszrem"  to the 
New PSN Earthquake Data Files page. The data source for this file is not my 
own, but derived from the posted file "030925.195008.osz". The modified file 
illustrates what can be done with digital signal processing to extend the useful 
period of a short period sensor. My file shows both the event as recorded from 
Osima, Italy, and after filtering. I have written a utility program to do such 
filtering on WinQuake Type 4 event files, which I can send to anyone who 
might want to try it out.

Regards,

Bob McClure
