On Saturday March 15 2008 at 7:44 AM (PDT) the USArray seismic network recorded an earthquake (preliminary Mw 5.7) located off the coast of Oregon.
Initial source parameters for this tremor are indicated below. The epicentral distance (i.e. distance separating the epicenter and the closest station in the recording network, H04A) for the USArray is 436 km (3.92 degrees).
If you felt the quake, the USGS would like to know. Please add your comments to the USGS page "Did you feel it?".
