Hi Chris,

I'm sorry, but at the time I posted my message, the following quake was still up on the CA, USGS map. (see below) But the USGS listed the closest city as Willow Creek. Of course, now that information has gone to the catalogs, so for ease in responding, I'm giving you the NEIC version. I don't think the second quake was an aftershock, but I suppose some might say that it is...I'll try to be a little more clear in future postings....Petra
