Moua Pihaa is a submarine volcano in French Polynesia. It is located southwest of Mehetia in the Society Islands, and is the largest of a group of seamounts stretching between Mehetia and Tahiti. The volcano's summit is 160m below sea level.[1]
The volcano was first located in 1976 using seismograph records, and its existence confirmed by a bathymetric survey.[2]
Moua Pihaa was seismically active from 22 to 29 April 1969, and from 21 to 23 June 1970, which suggests that submarine eruptions have occurred.[1]
