Pukarua, Tuamotu Archipelago

Located in the far eastern regions of the archipelago, Pukarua (Pukaruha) is situated 49 km northwest from Reao and 188 km northeast from Vahitahi. The atoll has an unusually narrow form, measuring 18 km in length with a maximum width of 7 km.

A single motu extends around the entire eastern side of the atoll (at top in the above image), broadening out at both the northwestern and southeastern extremeities of the atoll. The western rim is less prominent and contains many small islets in the northwest and shallow or exposed reef in the south. The enclosed lagoon is shallow, containing some reticulate reef formations and patch reefs.
