Rocard is a submarine volcano in French Polynesia, located between the island of Mehetia and the Teahitia seamount. The volcano's summit is 2515m below sealevel. [1] It has erupted in March 1966, September 1971, and July 1972. [1]

The volcano was first located in 1976 using seismograph records, and its existence confirmed by a bathymetric survey. [2]

In 2011 and 2013, seismic records suggested shallow magma outpouring from the volcano. [3]
