On Sunday July 18 2010 at 6:35 AM (PDT) the USArray seismic network recorded two earthquakes (preliminary Mw 6.9 and Mw 7.3) located in the New Britain region, Papua New Guinea.

Initial source parameters for these tremors are indicated below. The epicentral distance (i.e. distance separating the epicenter and the closest station in the recording network, L02D) for the USArray is 10123 km (90.96 degrees).

If you felt the quake, the USGS would like to know. Please add your comments to the USGS page "Did you feel it?".
