  abstract = {{T}he behaviour of a magma plumbing system during a cycle of volcanic edifice growth is investigated with a simple physical model. {L}oading by an edifice at {E}arth's surface changes stresses in the upper crust and pressures in a magma reservoir. {I}n turn, these changes affect magma ascent from a deep source to the reservoir and from reservoir to {E}arth's surface. {T}he model plumbing system is such that a hydraulic connection is maintained at all times between the reservoir and a deep magma source at constant pressure. {C}onsequently the input rate of magma into the reservoir is predicted by the model rather than imposed as an input parameter. {T}he open hydraulic connection model is consistent with short-term measurements of deformation and seismicity at several active volcanoes. {T}hreshold values for the reservoir pressure at the beginning and end of eruption evolve as the edifice grows and lead to long-term changes of eruption rate. {D}epending on the dimensions and depth of the reservoir, the eruption rate follows different trends as a function of time. {F}or small reservoirs, the eruption rate initially increases as the edifice builds up and peaks at some value before going down. {T}he edifice size at the peak eruption rate provides a constraint on the reservoir shape and depth. {E}difice decay or destruction leads to resumption of eruptive activity and a new eruption cycle. {A} simple elastic model for country rock deformation is valid over a whole eruptive cycle extending to the cessation of eruptive activity. {F}or large reservoirs, an elastic model is only valid over part of an eruptive cycle. {L}ong-term stress changes eventually lead to reservoir instability in the form of either roof collapse and caldera formation or reservoir enlargement in the horizontal direction.},
