Fig. 1.From: Volcano inflation prior to an eruption: Numerical simulations based on a 1-D magma flow model in an open conduit(a) Schematic illustration of the magma ascent process in an open conduit. (b) Spatial distribution of magma pressure in the conduit. Solid lines show the magma pressure at each stage. Dotted lines show the magma pressure just before an eruption. Chained line shows the magma pressure just after an eruption.Back to article page
