August 20, 2022 — View of Faleāsao tuff cone on Ta‘ū Island and Ofu-Olosega island in the distance
An afternoon view of the tuff cone near Faleāsao village located in northwest Ta‘ū island, with the islands of Ofu and Olosega visible in the distance. This tuff cone, which is thousands of years old, formed when hot magma interacted with either shallow groundwater or sea water. There are several tuff cones located within the northwest corner of Ta‘ū island. USGS photo by D. Downs.
