Ofu and Olosega are parts of a volcanic doublet in the Manu‘a Group of the Samoan Islands—part of American Samoa. Although geographically separate volcanic remnants, only a narrow strait (Asaga) naturally bridged by a shallow coral reef separates them. Before 1970, one had to wade between the two islands at low tide; now a single-lane road bridge over the strait connects villages on Ofu with those on Olosega.
