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).
