| Description
Volcanoes become active when fluids are in motion, and erupt when these fluids escape into the atmosphere. Volcanic fluids are a mixture of solid, liquid and gas. These mixtures result in a complex range of flow behaviour, especially during interaction with conduit geometry. These processes are not directly observable and must be inferred from interpretations of field observation and measurement. One of the outcomes of this complexity is the generation of pressure and force transients as high-density phases accelerate and decelerate during unsteady flow. These transients are one means of flexing the conduit wall, a process that manifests itself as ground motion and is detectable as volcano seismic signals. On eruption, volcanic fluids interact with the atmosphere and generate acoustic and thermal signals. In this Special Publication we present a series of papers based on field, numerical and experimental approaches that seek to establish links between geophysical signals and fluid motion in volcanic conduits. |

Reviews
......this Special Publication has been produced to a very high standard, owing to the well-written content, the logical layout and geographical scope of the papers, and the inclusion of detailed appendices and tables. The field and experimental photographs, illustrations, and graphs are generally of excellent quality (in particular those reproduced in colour), and provide a welcome visual reference point for the non-specialist in some of the more mathematical case studies. .........I consider Special Publication 307 to be a well produced, highly relevant, and welcome addition to the volcanological and geophysical literature.
