Hi Larry,
I have a question re: Winquake, and the P&S Marker location.  I recorded the
12/26/04 M9.0 event (along with everybody else) and the later 01/01/05 M6.5
event off Sumatra.  On both of these, I cannot get the P & S marker
locations on the record to align with the first arrival of the P and S waves
at my location.  For each event, Winquake does calculate the distance to my
location from the epicenter at 15000+ Km.

I am running the WQ version 2.9, if that info helps.  I have very carefully
checked my timing and event location data plugged into Winquake.  Do you
have any idea why the P & S calculation seems to be off?

If need be, I can email the two event records to you for your examination.
