Environmental Geology, 2004
Marine-geologic investigations on the Arabian Sea by Bundesanstalt fur Geowissenschaften und Rohstoffe (BGR) in 1995 and 1998, and land expeditions in 1998 and 1999 to the coastal regions of the Makran Desert/Pakistan have extended the knowledge of the aerial distribution of mud volcanoes.

Gas Emissions from Mud Volcanoes
2005There are about 1,000 mud volcanoes on land and 5,500 offshore — mostly in deep water. Activity varies between gentle emissions and violent eruptions accompanied by the release of enormous volumes of gas — mainly (85%+) methane and carbon dioxide. Global gas emissions are provisionally estimated to exceed 27 billion cubic metres per year, of which more

Methane Emission from Mud Volcanoes
2005Natural emission of methane from geologic sources has been recently recognized as an important component of the atmospheric methane budget. While some authors have focused their attention only on submarine gas seepage and gas hydrates, recent studies have suggested that also mud volcanoes (MVs) on land and microseepage in hydrocarbon-prone areas are ...

AAPG Bulletin, 1970
Quiescent and paroxysmally eruptive mud volcanoes are present on the Raukumara Peninsula of New Zealand. They extrude early Tertiary bentonitic mud with a few boulders from beneath a cover of late Tertiary sedimentary rocks, of which the aggregate thickness is about 20,000 ft (6,100 m).

Mud Volcanoes as Natural Strainmeters
2005Due to the sub-critical status of the seismogenic crust, relatively small strain fluctuations (>0.1 strain) induced by post-seismic stress redistribution could significantly affect the seismic hazard on a regional scale (tens to thousands of km) in the medium-term (months to tens of years).
