Descriptions
Steam-driven eruptions are explosions that frequently occur in volcanic and geothermal areas. They are powered by the sudden release and expansion of steam and liquid water trapped under high pressure within the pore spaces of host rocks. We have experimentally studied how the strength of rock hosting steam and liquid controls the nature of explosions based on examples from Lake Okaro (New Zealand). Specifically, we used experiments to estimate the relative amounts of energy that goes into breaking rock up, versus that required for ejecting particles upwards and outwards. Here we report the main methodological approach and results of petrophysical properties analyses, decompression experiments and estimation of explosivity of water, respectively.
Porosity and permeability Here the detailed methods are described for measuring porosity – derived from the pore volume measured with a helium pycnometer – and permeability by using a nitrogen gas permeameter. Decompression experiments Here detailed device and methods are described for decompression experiments including specifics on the shock tube apparatus, as well as on the determination of fragmentation and ejection velocities, and the size distributions of experimentally-fragmented material. Explosivity of gas and water Here are described theoretical basis of reversible and irreversible thermodynamic approaches that were used to estimate of the involved explosive energy for the different experimental conditions.
