Ahyi seamount (upper right) is a large submarine volcano that rises to within about 150 m of the sea surface about 18 km SE of the island of Farallon de Pajaros (left-center). At various times since 1979, water discoloration, felt seismicity followed by upwelling of sulfur-bearing water, and a seismically detected submarine eruption have been reported at or near the seamount. Two submarine volcanoes on the flanks of Farallon de Pajaros, Northwest Uracas and Makhahnas, are seen in this NOAA bathymetric image.
