Volcanotectonics and Geohazards: I extended the methods above, for the first time, to investigate fluid-driven seismicity in the shallow crust with particular focus on passive (triggered) seismicity in active volcanoes. These earthquakes in volcanic settings (known as Volcano-Tectonic, Hybrid and Low Frequency harmonic events) are diagnostic of conditions under the volcano and frequently detected before unrest. A new understanding of their generation in terms of fluid pressure, speed, and volume is now allowing new models to be developed for this important geological hazard, and better understand the key role that fluids have on the stability of volcanic flanks.Fluid-induced fracture mechanics: Fluids moving within a sealed impermeable rock mass will ultimately lead to fracture and failure due to over-pressurisation. This is both a natural phenomenon (e.g. veining, diking), and exploited during intentional hydraulic fracture. My research has successfully developed novel new apparatus to safely simulate this process at elevated pressure and temperature. These important new experiments have deconstructed the links between the high-pressure rock mechanics, fracture tip stresses, and the generated fracture energy (seismicity). This provides valuable information impacting the design of deep geological resources (e.g. Geothermal energy) as well as preventing unwanted fracturing, reducing risk and hazard in heat-generating processes (e.g. deep geological storage of nuclear waste).
|Dynamic Laboratory simulations of fluid-rock coupling with application to volcano seismicity and unrest.
Pore fluids play a key role in how crustal rocks deform, particularly in a volcanic environment where fluids span a wide range of types, and exist across a wide spectrum of temperature, pressure, and phase, influenced by the presence of the magmatic system at depth. Not only do pressurized pore fluids affect the mechanical properties and the elastic velocities of the host rock mass (volcanic edifice), they are also responsible for the generation of a range of seismic signals, for example Low Frequency (LF) tremor and Volcano-Tectonic (VT) seismicity generated due to shear fracture. This project tests the hypothesis that the presence of pore fluid delays the fracturing and the onset of microseismic activity, possibly explaining the sudden increase of precursory seismic activity before volcanic eruptions, and how fluids homogenize the rock material, decreasing the elastic wave anisotropy as they flow inside the newly formed cracks. I simulated these porcesses using advanced servo-controlled triaxial testing apparatus and state-of-the-art acoustic emission (AE) instrumentation: AE signals are the laboratory analogue of field-scale earthquakes, allowing the physics of the macro-scale events to be controlled under known P/T conditions. The depressurization of fluids reveals how different fluid phases contributes to form different spectral peaks, characterizing the fluid-induced signals. Recently, we have explored and simulated Tornillo events during gas depressurization, representing a new key link between earthquake features (such as amplitude modulation) and a physical properties (such as pressure transients).
|Coupled fluid-fracture mechanics in the applied geosciences: mechanical, temperature, and viscosity effects.
This project tackles two inter-related themes: 1). The safe operation of unconventional reservoirs requires not only extensive knowledge of the tensile fracture mechanics of the rock mass, but also how permeable new fracture networks are to different fluid types. In addition, elevated pore fluid pressures have a significant effect on rock mass stability via the effective stress pronciple. To better understand these dual challenges, this project uses controlled laboratory methods to link measured permeability of freshly generated fracture networks to the fracture density and geometry across a range of fluid types (water/slick-water, and oil), and with reference to the microseismic response during initial fracture, which itself may be used as a proxy for damage and fracture zone properties. 2). Elevated pore fluid temperatures and viscosities may have a detrimental effect on the rock mass stability via the lowered wetting effect and pore fluid activity. To better understand these issues, this project extends the conditions in (1) above to elevated reservoir conditions (geothermal and/or hydrocarbon) up to approximately 200C. Fracture data (density and aperture) is correlated across a range of fluid viscosities and temperatures: impossible in the typical field scenario. In both cases samples of 40mm diameter and 100mm length are encapsulated in a rubber jacket fitted with an 3D array for micro-acoustic sensors and instrumented for axial and radial strain. A central axial borehole is then pressurised within an outer shell of rock to simulate a range of depths to 4km by using high pressure hydraulics. Fracture area and size is derived from the spatio-temporal data, validated by post-test X-ray Computed Tomography.
|Fracture and permeability evolution of geothermal reservoirs using elastic moduli and elastic wave velocity (with EDC Ltd. and Northeastern Univ, CN).
Seismic based geophysical methods are seeing increased usage in evaluating geothermal resources in order to maximize resource potential. However, interpreting geophysical data (such as modulus and fracture density/alignment) generated from geothermal reservoirs remains difficult. This collaboration focuses on producing new laboratory data of seismic attributes of fresh and hydrothermally altered rocks from a Philippine geothermal field (Southern Negros Geothermal Project - SNGP). Two types of rocks were obtained by sub-coring samples of low porosity (~1%) andesite and higher porosity (~10%) volcaniclastic samples from the SNGP. The formation of shear fractures that weakens the material decreases the attributes while increasing pressure conditions that strengthens the material via fracture closure increases the overall properties. Samples are prepared with two offset drill holes to allow a natural fracture to permit fluid flow along the fracture. An embedded array of Acoustic Emission (AE) sensors allows elastic wave and induced microseismic data to be collected. Ultimately, the improved monitoring of geothermal reservoirs with seismic sensors (AE in the laboratory) has the potential to resolve both the 4D source and character of the event (e.g. source mechanism, frequency vs magnitude). Larger scale implementation of this would therefore be of benefit in understanding associated geohazards in high temperature geothermal fields.
|Investigating dynamic fracture processes in 'weak' volcanic rocks: applications to volcano seismology and forecasting (with Bristol, Dias (Dublin) and UCL Hazard Centre).
Volcano seismicity is an important tool in remotely monitoring and forecasting activity at volcanoes around the world. Volcanic earthquakes show diverse spectral characteristics, with shallow Long Period (Low Frequency) seismicity and long duration tremor generally interpreted as indicators of rapid fluid migration in fractures and faults, sometimes detected before eruption. This ongoing collaboration investigates how low-cohesion volcanic sediment from Campi Flegrei caldera (Italy) produces Low Frequency and long duration seismicity whilst undergoing deformation in dry conditions. Correlated X-Ray tomography of samples before and after deformation constrain the source as distributed damage. We have generated new evidence that Low Frequency events can be an indicator of slow-deformation within the edifice without fluids. Instead, strain is accommodated by weak volcaniclastic materials, particularly at low strain rates and confining pressures. This may relate to why low frequency seismicity is not always associated with eruption. Given the frequent observation of shallow ground deformation in volcanic settings, it seems likely the conditions for subjecting volcanic sediments to these types of conditions are widespread. We interpret these data by mapping/modelling the cumulative tensile stresses in order to better understand the cumulative energy in the volcanic system, and how this may be better used to forecast instability using field seismic data.
|Tensile driven fracturing in Volcano-tectonic settings: On the interplay of dyke injection and edifice stability (with Universities of Mainz and Turin).
This ongoing collaboration aims to simulate high pressure and high temperature processes operating during dyke movement in volcanic settings. Knowledge of this process is key to better understanding the eruption of magma, and how the stability of the volcanic edifice (rock mass) is influenced during the movement and emplacement of dyke swarms. Examples of unstable rock masses include volcano flank collapse problems as seen at Etna, Stromboli and El Hierro. We use a variety of methods including laboratory rock deformation and rock physics, remote sensing, and numerical situations to better understand the interaction between the soft magma and underlying sediments (e.g. carbonates and limestones particularly in the case of Mt Etna), and the harder basalts and other volcano products. We posit that the overall rock mass stability is governed not only by the hard layers but also eye the underlying softer sediments, and the fluids (including mamas) injected into these complex layered structures. In addition, cyclical stress regimes common in volcano settings may allow damage accumulation bu build up without warning resulting in catastrophic failure with little warning.
|Integrating multi-scale tomography techniques for determining the physical properties of the Earth from laboratory experiments to field scale (with UCL Hazard Centre, Mainz, Turin and INGV).
Scaling in the Earth sciences represents a fundamental and ongoing challenge. Structures in volcanotectonics typically cover a large range of scales typically across the hundreds of meters to km scales. However, laboratory methods are at best in dm (fraction of metre scale) but have the key advantage that conditions (pressure, temperature, strain) may be imposed and controlled to develop new theories. Linking these scales requires numerical models, geophysical data, and scale invariant methods to bridge these key gaps. In this ongoing collaborative project between Portsmouth, UCL Hazard Centre, INGV and the universities of Mainz and Turin, a series of new experiments, methods, and numerical approaches are being combined to better understand the underpinning science of calling across different geophysical parameters. Ultimately, these new data may be applied to updated fracture forecasting models and eruption prediction tools in volcano geophysics. We particularly focus on the volcanoes of St. Helens and the Campi Flegrei caldera (Italy) to test these ideas.
