This hydrothermally active submarine volcano at the southern part of the Mariana arc was first detected during a 2003 NOAA bathymetric survey and named NW Rota 1. The seamount rises to within about 500 m of the ocean surface, about 100 km N of Guam. A minor eruption was witnessed in 2004 at the Brimstone Pit vent.
