The source of material and energy of eruption of mud volcanoes are of endogenic processes. Landscapes of mud volcanoes, such as mud cone, mud shield, mud marr, mud basin, and mud hole, are the products of interactions between endogenic processes and exogenic processes. Landscapes of mud volcanoes vary spatially and temporally with their sensitivity and recovery ability. Take for examples mud volcanoes along the Chihshan Fault, southwestern Taiwan., The landscape of a mud volcano varies with its occurrence relative to the trace of Chihshan Fault, because the fault activity supports the recovery ability of the landscape. And the size, degree of activity and the surroundings of mud volcanoes determine the erosivity of the landscape of mud volcanoes. The recovery process is constructive to the mud volcano system, while the erosive process is destructive to the system. This stu
