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
