Report on West Mata (Tonga) — December

Finally, they note that East Mata (figure 3), a similar volcano ~km closer to the Tofua arc, is also hydrothermally active, albeit less intense than West Mata. FigureThe two The West Mata volcano is located in the South Pacific and scientists hope to return to the volcano this year to capture more activity on film. Follow the Vents program online for · Among the sites discovered was West Mata volcano, the largest and most active edifice in a cluster of nine similarly-shaped boninite volcanoes located in the rear-arc portion of the tectonically complex NE Lau basin. West Mata lies ∼km west of the active Tofua volcanic arc,km east of the back-arc NE Lau Spreading Center (NELSC), and West and East Mata volcanoes support diffuse flow hydrothermal systems. Active focused-flow hydrothermal systems occur onN. Mata volcanoes (Fa, Tolu, Ono, Fitu), with an inactive system at Mata Taha. Each has distinct vent field sizes and locations on the volcanoes (summit, base, other), and chimney sizes, shapes and spacingWest Mata, which the scientists estimate has been erupting for at least three years, and eight other elongated volcanoes that overlap each other in the northeast Lau Basin sit within one of the most magmatically active areas on Earth, Resing says Compared to the other Mata group volcanoes, West Mata is the most hydrothermally active one and its' activity is not disputed. Geography. West Mata can be found in the northeastern portion of Tonga, in between Fiji and Samoa. It is located approximately km (mi) southwest of the Samoan Islands and around km (mi) northeast of the

Why is Iceland prone to earthquakes? Volcanic activity explained

At the same time West Mata was discovered, multiple neighboring volcanoes—most of them hydrothermally active—were discovered as well, including Volcano O, Tafu Scientists first detected signs of eruptions at West Mata, a small active seamount ~ km SW of Samoa, in when a particle-rich plume was identified ~ m above the · The volcano was first discovered in by scientists aboard the R/V Thompson research vessel, using sonar mapping and a remotely operated vehicle (ROV) to explore the seafloor. At the same time West Mata was discovered, multiple neighboring volcanoes—most of them hydrothermally active—were discovered as well, including Volcano O, Tafu · Deep Ocean Volcanoes Learn about underwater volcanoes like Hunga Tonga-Hunga Ha’apai, and the discovery of the erupting deep-ocean volcano West Mata. Students can view an animation of the oceanWithin a little more than an hour of reaching the bottom at West Mata on the first dive an active eruption was discovered at 1, m (3, ft) near the summit of the volcano. The eruption was characterized by glowing molten lava, explosions, the creation of large amounts of volcanic sands, and the active formation of pillow lavas Among the sites discovered was West Mata volcano, the largest and most active edifice in a cluster of nine similarly-shaped boninite volcanoes located in the rear-arc portion of the tectonically complex NE Lau basin. West Mata lies ∼km west of the active Tofua volcanic arc,km east of the back-arc NE Lau Spreading Center (NELSC), and

Antarctica's only active volcano shows how CO2 allows volcanoes

Nearly feet below the surface of the Pacific Ocean – in an area between Samoa, Fiji and Tongathe West Mata volcano was discovered. The explosions of molten rock ,  · The West Mata Volcano, encircled by a white ellipse on this bathymetric map, is not the largest volcano in the northeast Lau Basin, but appears to be the most Within a little more than an hour of reaching the bottom at West Mata on the first dive an active eruption was discovered at 1, m (3, ft) near the summit of the volcano. The eruption was characterized by glowing molten lava, explosions, the creation of large amounts of volcanic sands, and the active formation of pillow lavas.  West Mata volcano (figure 2) was very likely erupting lava flows and/or pyroclastic material at this time. The intense plume rising ~ m from the summit that was characterized by high values of turbidity, hydrogen, delta helium(dHe), oxidation-reduction potential (Eh), and pH. The acoustic backscatter over portions of the volcano was
