Ofu and '''Olosega''' are parts of a volcanic doublet in the Manu‘a Group of the Samoa Archipelago—part of American Samoa . Although geographically separate volcanic remnants, only a narrow straight (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 road bridge over the straight connects villages on Ofu with those on Olosega. OFU Ofu is the western part of the volcanic outcrop of Ofu-Olosega Island. The main village of Nu‘usilaelae is located on the western shore, protected behind an offshore islet (eroded Tuff Cone ) known as Nu‘utele. Ofu has a small airport and a boat harbor that serve the population on Ofu and Olosega. The southern shore and associated coral reef are part of the National Park Of American Samoa . The U.S. National Park Service is presently (2005) negotiating with village councils on Olosega to expand the park around that island. OLOSEGA Olosega Island is a remnant of the Sili shield volcano, the caldera of which may lie submerged off the north shore. The undersea eruption of 1866 was actually 3 km east of Olosega, on a submarine ridge that extends eastsoutheast to nearby Ta‘ū . There are two villages on Olosega: Olosega and Sili. Sili now consists of but one standing residence after much of the village was destroyed by hurricanes (and subsequently abandoned). Nearly all of the population of Olosega now resides in Olosega village along the southwestern-facing shore. REFERENCES
