Concepción Volcano is one of the tallest and most active of Nicaragua’s volcanoes. The 1,610-meter (5,280-foot), cone-shaped volcano is the northern half of dumbbell-shaped Isla de Ometepe. To the northwest of the crater, a very faint plume (probably steam) creeps like fog down the mountain, blurring the sharp gullies that carve the volcano’s flanks.
Acquired February 11, 2010, this true-color image shows water discoloration immediately west of the underwater summit of Fukutoku-Okanoba. Clouds overhead might result from vapor emissions, but might be unrelated to volcanic activity.
