Journal Article
Horwell, C. J., Damby, D. E., Stewart, C., Joseph, E. P., Barclay, J., Davies, B. V., …Tunstall, N. (2024). Physicochemical hazard assessment of ash and dome rock from the 2021 eruption of La Soufrière, St Vincent, for the assessment of respiratory health impacts and water contamination. Geological Society Special Publications, 539(1), https://doi.org/10.1144/sp539-2023-46

La Soufrière, St Vincent, began an extrusive eruption on 27 December 2020. The lava dome was destroyed, along with much of the pre-existing 1979 dome, in explosive eruptions from 9 to 22 April 2021. Lava domes generate crystalline silica – inhalation...

Controls on post-seismic landslide behaviour in brittle rocks (2021)
Journal Article
Brain, M., Moya, S., Kincey, M., Tunstall, N., Petley, D., & Sepúlveda, S. (2021). Controls on post-seismic landslide behaviour in brittle rocks. Journal of Geophysical Research: Earth Surface, 126(9), Article e2021JF006242. https://doi.org/10.1029/2021jf006242

Earthquakes trigger widespread landsliding in tectonically-active landscapes. The effects of strong ground shaking on hillslope stability persist into the post-seismic stage; rates of landsliding remain elevated in the years following an earthquake....

Late Holocene paleoseismology of Shuyak Island, Alaska (2018)
Journal Article
Shennan, I., Brader, M. D., Barlow, N. L., Davies, F. P., Longley, C., & Tunstall, N. (2018). Late Holocene paleoseismology of Shuyak Island, Alaska. Quaternary Science Reviews, 201, 380-395. https://doi.org/10.1016/j.quascirev.2018.10.028

We report stratigraphic evidence of land-level changes along the eastern portion of the Alaska-Aleutian megathrust. Four marshes on Shuyak Island record variable amounts of coseismic deformation during four pre-20th century earthquakes. We combine th...

The control of earthquake sequences on hillslope stability (2017)
Journal Article
Brain, M., Rosser, N., & Tunstall, N. (2017). The control of earthquake sequences on hillslope stability. Geophysical Research Letters, 44(2), 865-872. https://doi.org/10.1002/2016gl071879

Earthquakes trigger landslides in mountainous regions. Recent research suggests that the stability of hillslopes during and after a large earthquake is influenced by legacy effects of previous seismic activity. However, the mechanisms that control hi...

The Effect of Dynamic Loading on the Shear Strength of Pyroclastic Ash Deposits and Implications for Landslide Hazard: The Case of Pudahuel Ignimbrite, Chile (2016)
Journal Article
Sepúlveda, S., Petley, D., Brain, M., & Tunstall, N. (2016). The Effect of Dynamic Loading on the Shear Strength of Pyroclastic Ash Deposits and Implications for Landslide Hazard: The Case of Pudahuel Ignimbrite, Chile. Engineering Geology, 205, 54-61. https://doi.org/10.1016/j.enggeo.2016.02.005

The co-seismic and post-seismic behaviour of pyroclastic ash deposits and its influence on slope stability remains as a challenging subject in engineering geology. Case studies in volcanic areas of the world suggest that soil structural changes cause...

The effects of normal and shear stress wave phasing on coseismic landslide displacement (2015)
Journal Article
Brain, M., Rosser, N., Sutton, J., Snelling, K., Tunstall, N., & Petley, D. (2015). The effects of normal and shear stress wave phasing on coseismic landslide displacement. Journal of Geophysical Research, 120(6), 1009-1022. https://doi.org/10.1002/2014jf003417

Predictive models used to assess the magnitude of coseismic landslide strain accumulation in response to earthquake ground shaking typically consider slope-parallel ground accelerations only and ignore both the influence of coseismic slope-normal gro...
