The Makran accretionary complex is characterized by a number of features associated with escaping water and methane . Mud volcanoes are found onshore in both Iran and Pakistan , and cold seeps exist offshore . The formation of an island ( Zalzala Jazeera ) after the 2013 Balochistan earthquakes is thought to be the result of a mud volcano . An island ( Malan island ) formed as a mud volcano subsided under water due to gas release and mud extrusion . Heavy rain from monsoon season built pressure to the aquifer , enhancing the release of gas .
