A bedform phase diagram for dense granular currents (2020)
Journal Article

Pyroclastic density currents (PDCs) are a life-threatening volcanic hazard. Our understanding and hazard assessments of these flows rely on interpretations of their deposits. The occurrence of stratified layers, cross-stratification, and bedforms in... Read More about A bedform phase diagram for dense granular currents.

Generating long period and tremor-like seismicity without fluids in volcanic materials (2020)
Presentation / Conference Contribution

Volcano seismicity is routinely used in the remote monitoring and forecasting of activity at volcanoes around the world. The nature of this seismicity varies, but long period (LP) seismicity is generally interpreted as an indicator of fluid migration...

Velocity profiles in sedimenting pyroclastic density currents (2020)
Presentation / Conference Contribution

Pyroclastic density currents pose a threat to life at active volcanoes around the world, and mitigation of their impacts requires a better understanding of their complex flow behaviours. Understanding the internal dynamics of these flows, and how the... Read More about Velocity profiles in sedimenting pyroclastic density currents.

Laboratory simulations of fluid-induced seismicity, hydraulic fracture, and fluid flow (2019)
Journal Article

Fluid-induced seismicity has been observed and recorded for decades. Seismic energy necessarily requires a source, which is frequently related to rock fracture either in compression or tension. In both cases, such fracture may be promoted by crustal... Read More about Laboratory simulations of fluid-induced seismicity, hydraulic fracture, and fluid flow.

Reconstructing the Anak Krakatau flank collapse that caused the December 2018 Indonesian tsunami (2019)
Journal Article

Volcanogenic tsunamis are one of the deadliest volcanic phenomena. Understanding their triggering processes, and mitigating their effect, remains a major challenge. On 22 December 2018, flank failure of the Anak Krakatau volcano in Indonesia generate...

Inferring pyroclastic density current flow conditions using syn-depositional sedimentary structures (2019)
Journal Article

The processes occurring in the basal region of concentrated pyroclastic density currents (PDCs) influence the mobility, runout distance, and damage potential of a current, but directly observing these processes is extremely difficult. Instead, we mus... Read More about Inferring pyroclastic density current flow conditions using syn-depositional sedimentary structures.

Investigation of variable aeration of monodisperse mixtures: implications for pyroclastic density currents (2018)
Journal Article

© 2018, The Author(s). The high mobility of dense pyroclastic density currents (PDCs) is commonly attributed to high gas pore pressures. However, the influence of spatial and temporal variations in pore pressure within PDCs has yet to be investigate...

Fracture and damage localization in volcanic edifice rocks from El Hierro, Stromboli and Tenerife (2018)
Journal Article

© 2018 The Author(s). We present elastic wave velocity and strength data from a suite of three volcanic rocks taken from the volcanic edifices of El Hierro and Tenerife (Canary Islands, Spain), and Stromboli (Aeolian Islands, Italy). These rocks span... Read More about Fracture and damage localization in volcanic edifice rocks from El Hierro, Stromboli and Tenerife.

Morphological and Mechanical Biomimetic Bone Structures (2017)
Journal Article

© 2016 American Chemical Society. Cortical bone is an example of a mineralized tissue containing a compositional distribution of hard and soft phases in 3-dimensional space for mechanical function. X-ray computed tomography (XCT) is able to describe... Read More about Morphological and Mechanical Biomimetic Bone Structures.

Key future directions for research on turbidity currents and their deposits (2015)
Journal Article

© E 2015, SEPM (Society for Sedimentary Geology). Turbidity currents, and other types of submarine sediment density flow, redistribute more sediment across the surface of the Earth than any other sediment flow process, yet their sediment concentratio...
