Volcano Triplets Spotted Erupting
Three active volcanoes simultaneously erupting and unleashing giant plumes of smoke were spotted by a NASA satellite as it passed over a remote archipelago in the South Atlantic Ocean.
The three stratovolcanoes — a type of composite volcano built of layers of lava, ash and stone — are located on the South Sandwich Islands, which are about 1,700 miles (2,800 kilometres) southeast of Buenos Aires, Argentina. Volcanoes in the region are some of the least studied in the world, because of the remote location and inhospitable environment of the islands.
On Sept. 29, NASA's Aqua satellite captured the plumes from these volcano triplets in a false-colour image. Clouds and ice in the region make it difficult for satellites to see volcanic activity in natural-colour imagery.
