Data from the Global Volcanism Program of the Smithsonian Institution
Details for: NW Rota-1
An eruption plume rises from a submarine vent on NW-Rota 1 volcano on 27 April 2006. This volcano was first detected during a 2003 NOAA bathymetric survey of the Mariana Island arc. The seamount rises to within about 500 m of the sea surface SW of Esmeralda Bank. During subsequent visits in 2005, 2006, and 2008, the volcano was seen to be in eruption.

A submarine volcano detected during a 2003 NOAA bathymetric survey of the Mariana Island arc was found to be hydrothermally active and named NW Rota-1. The basaltic to basaltic andesite seamount rises to within 517 m of the ocean surface SW of Esmeralda Bank, 64 km NW of Rota Island and ~100 km N of Guam. When Northwest Rota-1 was revisited in 2004, a minor submarine eruption from a vent named Brimstone Pit on the upper south flank about 40 m below the summit intermittently ejected a plume several hundred meters high containing ash, rock particles, and molten sulfur droplets that adhered to the surface of the remotely operated submersible vehicle. The active vent was funnel-shaped, about 20 m wide and 12 m deep. Prominent structural lineaments about a kilometer apart cut across the summit of the edifice and down the NE and SW flanks.
