Global Volcanism Program | Image GVP-10687

Clouds drape the tops of the two islands of Ofu (left) and Olosega (right) in eastern Samoa in this Space Shuttle image (N is to the top left). The islands, 6 km in combined length, are separated by a narrow strait. They are formed by two eroded, coalescing basaltic shield volcanoes truncated by mostly-submarine calderas. A submarine eruption took place in 1866 about 3 km SE of Olosega, along the ridge connecting Olosega with Ta'u Island. NASA Space Shuttle image ISS002-E-6878, 2001 (http://eol.jsc.nasa.gov/).
