|From USGS web site|
The news coverage has been good this morning. The earthquake summary can be found here on the USGS web site: http://earthquake.usgs.gov/earthquakes/eventpage/usb000t1hf#summary. Looks like the focus was at a depth of just over 6 miles (an earthquake focus is the exact place within the earth where the crust broke to create the quake). The epicenter (defined as the place on the surface directly above the focus) was located seven miles north of Sedona and just east of the Butterfly Garden Resort in the canyon. A preliminary view of the epicenter suggests this quake likely occurred along the Oak Creek Canyon fault.

Twitter carried a picture of rocks and trees on Highway 89A that were let loose during the shaking.
I will make updates as they become available.
