The data you request used to be listed a lot more often that it is now.  =
I checked the current list of recent earthquakes and only found it the =
data listed on two events, the M 8.8 Chile, and the M 7.0 Ryukyu =
Islands.  When listed you will find it under the Scientific & Technical =
tab, and it is called Seismicity Cross Section.  I also checked most of =
the M 6.0 + listings on the 8-30 day list and did not find any with =
Seismicity Cross Section.  I can remember this being listed much more =
often a few years ago than is currently done.

The published focal mechanism is another source for the fault geometry =
at the point of rupture, but it does not give the overall long view that =
you obtain with Seismicity Cross Section.=20
