September 3, 2025 – View of the north side of Ofu Island, American Samoa

USGS Hawaiian Volcano Observatory scientists and NOAA National Weather Service Weather Service Office Pago Pago meteorologists travelled by boat between the Manuʻa Islands, American Samoa, during an outreach and monitoring network maintenance trip in early September 2025. This view is from the boat looking south towards the north side of Ofu Island. The Asaga Bridge connecting Ofu Isand (right) and Olosega Island (left) is visible on the left. Ofu-Olosega volcano last erupted in 1866 C.E. with an eruption about 2 miles (3 kilometers) southwest of Olosega Island. USGS photo by N. Deligne.
