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]

<span class="mw-page-title-main">Tautira Bay</span>

Tautira Bay is located on the island of Tahiti in French Polynesia. It is part of the commune Taiarapu-Est. It is formed by Tautira Point and reef on the eastern side, and by the barrier reef on the western side. It is reached through a gap in the reef about half a mile wide, with deep water, with Tautira point giving it protection from winds from north-east. It is 0.5 miles (0.80 km) wide and about the same depth. The bay opens to the northwest, affording protection with winds from northeastward through east and south to west-northwestward, but can be dangerous with those between north and west-northwestward. James Cook anchored several times in this bay, from which circumstance the name is derived. The depth in the middle of the entrance is from 35 to 60 fathoms, diminishing gradually to the shore. The bay is clear, except a small patch of 2 fathoms 600 feet (180 m) southward of the point of reef on the western side. The eastern and southeastern shore is lined with a sandy beach. The best anchorage is at about 1,200 feet (370 m) from the shore in 8.5 fathoms, sand, with the extreme of Tautira Point bearing 45°.

It is about 7-8 million years old, although a large earthquake recorded at its position in 1955 may indicate a recent eruption.
