Ja, we watched the quakes pile up real time on the
web.  Someone has figured out a way to estimate the
epicenter and magnitude within a couple minutes of
the actual shake.  I compared the accuracy of the
initial estimates with the final calcs.  The initial
estimates were very close in every case.  Kewall!  {8-]  spike

Parkfield was loaded with USGS instruments, and a quake was expected
back.  One of my neighbors built some of the instruments.  Hopefully
they'll get 
some wonderful insights from the mass of collected data.
