Journal Article
Walding, N., Williams, R., Rowley, P., Dowey, N., Parsons, D., & Bird, A. (2025). Behaviours of pyroclastic and analogue materials, in dry and wet environments, for use in experimental modelling of pyroclastic density currents. Volcanica, 8(1), 261-285. https://doi.org/10.30909/vol/oxkm9163

Modelling pyroclastic density currents (PDCs) is a challenging yet essential element of hazard assessment. PDCs are unpredictable and internal processes are often difficult to measure directly. Analogue experiments have been an important tool for inv...

The influence of moisture on ash strength: implications for understanding volcanic stratigraphy (2025)
Journal Article
Walding, N., Williams, R., Dowey, N., Rowley, P., Thomas, M., Osman, S., Johnson, M., & Parsons, D. R. (2025). The influence of moisture on ash strength: implications for understanding volcanic stratigraphy. Bulletin of volcanology, 87(6), Article 39. https://doi.org/10.1007/s00445-025-01821-4

Ash layers within extensive pyroclastic density current (PDC) deposits can be important in understanding the evolution of explosive eruptions. If interpreted as ashfall deposits, they may be used to identify hiatus episodes and determine how many pyr...

Earth Science, Systems and Society, 4, Article 10123. https://doi.org/10.3389/esss.2024.10123

There is a well-documented racial and ethnic diversity crisis in Geography, Earth and Environmental Sciences (GEES) subjects in the Global North that leads to inequities in who does environmental research. The Equator project set out to increase part... Read More about The Equator Project Research School and Mentoring Network: Evaluated Interventions to Improve Equity in Geoscience Research.

Cohesional behaviours in pyroclastic material and the implications for deposit architecture (2023)
Journal Article
Walding, N., Williams, R., Rowley, P., & Dowey, N. (2023). Cohesional behaviours in pyroclastic material and the implications for deposit architecture. Bulletin of volcanology, 85(11), Article 67. https://doi.org/10.1007/s00445-023-01682-9

Pyroclastic density currents (PDCs) are hazardous, multiphase currents of heterogeneous volcanic material and gas. Moisture (as liquid or gas) can enter a PDC through external (e.g., interaction with bodies of water) or internal (e.g., initial erupti...

Anatomy of a volcanic eruption undersea (2023)
Journal Article

In December 2021, an undersea volcano in the southern Pacific Ocean, the Hunga Tonga–Hunga Ha‘apai (hereafter called the Hunga volcano) began erupting. In January 2022 the eruption reached a powerful climax, triggering atmospheric waves that traveled... Read More about Anatomy of a volcanic eruption undersea.

Strategies for making geoscience PhD recruitment more equitable (2023)
Journal Article
Fernando, B., Giles, S., Jackson, C., Lawrence, A., Raji, M., Williams, R., Barclay, J., Brotherson, L., Childs, E., Houghton, J., Khatwa, A., Newton, A., Mills, K., Rockey, F., Rogers, S., Souch, C., & Dowey, N.

Admission to doctoral study is a crucial step in the academic pipeline, but discriminatory procedures can disproportionately impact students from ethnic minority backgrounds. We show how these policies contribute to inequity in the geosciences and pr... Read More about Strategies for making geoscience PhD recruitment more equitable.

Simultaneous fall and flow during pyroclastic eruptions: A novel proximal hybrid facies (2022)
Journal Article
Dowey, N., & Williams, R. (2022). Simultaneous fall and flow during pyroclastic eruptions: A novel proximal hybrid facies. Geology, 50(10), 1187-1191. https://doi.org/10.1130/G50169.1

The deposits of Plinian and subplinian eruptions provide critical insights into past volcanic events and inform numerical models that aim to mitigate against future hazards. However, pyroclastic deposits are often considered from either a fallout or... Read More about Simultaneous fall and flow during pyroclastic eruptions: A novel proximal hybrid facies.

Geology Uprooted! Decolonising the Curriculum for Geologists (2022)
Journal Article

Geology is colonial. It has a colonial past and a colonial present. Most of the knowledge that we accept as the modern discipline of geology was founded during the height of the post-1700 European empire's colonial expansion. Knowledge is not neutral...
