The two sensors were deployed off the Solomon Islands and will provide real-time data about destructive waves that could threaten Hawaii, the U.S. territories in the Pacific, the West Coast and Pacific Rim nations.
NOAA said tsunami stations are now positioned between Hawaii and every seismic zone that could generate a tsunami affecting the United States.
Buoys in the western Atlantic, Gulf of Mexico and Caribbean have been monitoring the East and Gulf coasts.
The stations consist of a bottom pressure sensor anchored to the sea floor and a companion moored surface buoy. Acoustic and satellite links relay the data to NOAA.
Since the deadly South Asia tsunami in December 2004, NOAA has expanded the buoy network from six in the eastern Pacific to 39 across the Pacific and Atlantic.
