A bathymetric map prepared during a NOAA Vents Program expedition in November 2008 shows two submarine volcanoes, Tafu (Tongan for "source of fire") and Maka (Tongan for "rock"). The volcanoes lie along a NE-SW-trending ridge on the southern part of the back-arc NE Lau Spreading Center (NELSC). The November 2008 expedition discovered submarine hydrothermal plumes consistent with recent (maybe days to weeks) submarine lava effusion from Maka volcano.
