'''Ofu''' and '''Olosega''' are parts of a volcanic doublet in the [[Manua|Manu‘aManuʻa GroupIslands]], ofwhich theis [[Samoana Islands]]—part of [[American Samoa]]. in the [[Samoan Islands]]. TheThese twin islands, formed from [[shield volcanoesvolcano]]es, have a combined length of 6  km and ana combined area of {{convert|12|km2|0|abbr=off|sp=us}};. theirTogether, they have a population isof about 500 people.

Ofu is the western part of the volcanic outcrop of Ofu-Olosega Island and the westernmost of the Manu'a Islands.<ref name="auto">Hills, J.W. (2010).

Page 63. {{ISBN|9781147952896}}.</ref> The main village of [[Ofu Island|Ofu]] is located on the western shore, protected behind an offshore islet (eroded [[tuff cone]]) known as [[Nu'uteleNuʻutele (American Samoa)]]. Ofu has a [[Ofu Airport|small airport]] {{Airport codes|OFU|NSAS}} and a boat harbor that serve the population on Ofu and Olosega. The twice-weekly flight from [[Pago Pago]] takes about half an hour.

Most of the southern shore and associated coral reef are part of the [[National Park of American Samoa]]. In 2005 the U.S. [[National Park Service]] was negotiating with village councils on Olosega to expand the park around that island.

The island forms the [[Ofu County]] subdivision of the [[Manua|ManuaManuʻa District]]. It has a land area of 7.215&nbsp; km²² (2.786 sq mi), and had an official population of 176 persons as of the [[2010 United States Census, 2010census|2010 census]].

The volcanic eruption of 1866 was actually {{convert|3|km|mi|abbr=on}} east of Olosega, on a [[submarinemid-ocean ridge]] that extends east southeast to nearby [[Tau, Samoa|Ta‘ūTaʻū]].

The island forms the [[Olosega County]] subdivision of the [[Manua|ManuaManuʻa District]]. It has a land area of 5.163&nbsp;km²² (1.993 sq mi), and had an official population of 172 persons as of the 2010 census.

There are four villages on Olosega: [[Olosega (Village)|Olosega]], [[Lalomoana]], [[Sili (Olosega)|Sili]], and [[Faiava]].
