Jon -

The two Oregon events occurred on the North side of the Blanco Fracture Zon=
e
(Blanco Transform), part of the Mendocino Triple Junction.  It is a highly
seismically active area already noted for frequent earthquakes.  A search o=
f
USGS records for the last 30 days revealed 17 events that preceded these tw=
o
events. =20

In April 2008, there was a swarm offshore of Oregon, and north of the Blanc=
o
Fracture Zone.  This swarm had over 700 events.  Following is a link to a
USGS report on the previous swarm:
