Pillow lavas on the western rift of Vailulu'u volcano with exotic marine life, photographed during a NOAA Ocean Explorer expedition in 2005. Two principal rift zones extend E and W from the summit of the submarine volcano, parallel to the trend of the Samoan hotspot. Not discovered until 1975, this seamount rises 4,200 m from the sea floor to a depth of about 600 m and displays evidence of hydrothermal venting.
