last updated: 04/09/08 08:20.10 (PDT)
On Wednesday April 9 2008 at 5:46 AM (PDT) the USArray seismic network recorded an earthquake (preliminary Mw 7.6) located near the Loyalty Islands in the western Pacific Ocean.
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, SNCC) for the USArray is 9622 km (86.44 degrees).
If you felt the quake, the USGS would like to know. Please add your comments to the USGS page "Did you feel it?".
