Rocard is a recently discovered submarine volcano about halfway between Tahiti and Mehetia islands. It displayed seismicity in 1966, 1971, and 1972 that may have resulted from submarine eruptions (Talandier and Custer, 1976). Rocks dredged from the volcano in 1986 "exploded" when they reached the surface, suggesting recent lava extrusion that had not yet had time to equilabrate with pressure and temperature conditions on the submerged flanks of the edifice. The summit of Rocard lies 2100 m below sea level east of Teahitia seamount and north of Moua Pihaa seamount. Rocard is much smaller than its neighboring seamounts.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
