 The activity of onshore mud volcanoes may affect the stability of infrastructure and man-made underground structures through the eruption of huge volumes of mud and groundwater. For example, the LUSI mud volcano in Indonesia has erupted vast amounts of groundwater and mud since 2006, causing serious problems with respect to the ground surface and affecting the lives of local residents. The ascension of highly saline and pressurized groundwater from deep underground at mud volcanoes destroys man-made underground structures by hydro-fracturing and forms mud breccia, which adversely affects tunnel construction due to its swelling nature. Ascending groundwater increases the pore water pressure along the landslide plane and consequently triggers landslides as well as the activity of mud volcanoes. In addition, regional groundwater flow caused by ascending pressurized groundwater may result in the long-term stability of the groundwater.<br> Furthermore, the migration of highly saline groundwater causes rapid weakening and erosion of sedimentary rock via the interaction of clay minerals and groundwater. It is assumed that the volume of methane, a potent greenhouse gas, released during eruptions of mud volcanoes is sufficiently large that it affects global warming. Because onshore areas support considerable human activity and the activity of the mud volcanoes can potentially cause many problems, investigation of the geological and hydrological phenomena related to mud volcanoes is warranted.
