The Vanuatu Archipelago is a collection of volcanic islands about 1,800 kilometers (1,100 miles) northeast of Australia. Two of the islands, Gaua and Ambrym, frequently vent sulfurous gases. In this natural-color satellite image, a volcanic plume from Ambrym spreads across the South Pacific.
This natural-color image was collected on January 7, 2014, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite.
