Hi Jim
   What I find interesting is that USGS shows two 6+ events about 30 minutes apart. I have a hard time seeing the second event start (P & S wave arrivals). It's like my sensors focus on the first event. I don't have a problem with local events though.

          PSN friends--perhaps you have noticed the Rat Island swarm of seismic events---over 50 in the first 12 hours UT of June 14, '06.  Magnitudes range from 2.5 to 6.3.
     For those in range of 2 or more of these events--such conditions make for good magnitude comparisons & local system calibration.
     Latitude and longitude & depths of origins vary a bit.  One can stand amazed at the resolution the professionals have in a swarm as this.
      A good day to all----Jim Lehman
