Chris,
Several months ago, SCEC decided not to report events to the USGS list until
they had been completely finalized. This means that the list you use is never
up to date any longer.. Events may take several weeks to finalize and often will
not appear on that list at all because the map and list are for the past 7 days,
and finalized events are often not available in that time. Following is a note
Kate Hutton sent me regarding this on Sept. 26:

Date: Wed, 26 Sep 2001 06:57:21 -0700 (PDT)
"Lowell, I should mention that we have made a change in the Simpson map (Recent
Earthquakes in California/Nevada) for southern Cal. We started updating the map

following post-processing. This means that bogus events should disappear and a
few more small ones should show up, but not right away. This started last week.

Better to use the SCSN listing the the Simpson map. The alternative is to use the
on-line catalog which you can ftp from the following site:
ftp scec.gps.caltech.edu (login: anonymous; password: Your e-mail address)
cd pub
cd catalogs
cd SCSN
get YEAR.cat

This catalog is updated regularly. A catalog which is updated even more often
is still at :
ftp crustal.ucsb.edu
login: anonymous
Password: your e-mail address
cd pub
get scal.eq
Northern california catalog is also there at
get ncal.eq
