  abstract = {{W}e compared the structure of two flat and two conical mud volcanoes ({MV}) in {A}zerbaijan in order to understand what governs the morphological contrast. {W}e paid particular attention to the structural evolution of the surface, as observed in the field over 5 years and as monitored by satellite images revealing surface activity over that period; in addition, we acquired microgravity measurements to probe deeper structure. {T}he combination of these data reveals in all studied volcanoes significant mass deficit concentric with the surface edifice. {M}odeling indicates that the mass deficit is consistent with a chamber underlying the summit caldera of conical {MV}s and the plateau of flat {MV}s, with a thickness of several hundred meters for a density contrast of 500 kg/m3 between the chamber mud and the surrounding solid mud. {S}urface structures and their evolution during and in between eruptions provide insight into the depth of the mud chamber, which lies within a few meters of the surface for flat mud volcanoes and one to several hundred meters deep for conical ones. {S}urface structures and satellite-derived deformation analysis shows that flat mud volcanoes grow by radial expansion and compression of the flanks distributed all around the edifice. {I}n contrast, conical mud volcanoes grow by flow stacking in the summit caldera, deformation being constrained by the caldera rim; excess mud supply is accommodated by occasional rim breaching and mud overflow into flank gullies.},
