English: This natural-colour image shows the most dramatic group of mud volcanoes in the area, known as the Changradup Complex, Pakistan. The tallest mud volcano, Changradup I, is about 100 meters high, and it has a 15-meter diameter mud lake in its crater that periodically overflows. Some of these overflows have darkened the north-western flanks. A second crater emerges from the southern flanks of Changradup, but it is not currently active. The 45-meter Chandragup II lies north-east of the taller cone, and its crater is filled by a mud lake with a figure-8 shape, probably the result of twin volcanoes whose craters collapsed into each other over time. To the north-west of Changradup I, the eroded rim of an extinct mud volcano is visible; its eastern rim is more noticeable than its western rim.
