A reappraisal of explosive–effusive silicic eruption dynamics: syn-eruptive assembly of lava from the products of cryptic fragmentation (2022)
Journal Article
Wadsworth, F. B., Llewellin, E. W., Castro, J. M., Tuffen, H., Schipper, C. I., Gardner, J. E., …Whattam, J. (2022). A reappraisal of explosive–effusive silicic eruption dynamics: syn-eruptive assembly of lava from the products of cryptic fragmentation. Journal of Volcanology and Geothermal Research, 432, https://doi.org/10.1016/j.jvolgeores.2022.107672

Silicic volcanic eruptions range in style from gently effusive to highly explosive, and may switch style unpredictably during a single eruption. Direct observations of subaerial rhyolitic eruptions (Chaiten 2008, Cordón Caulle 2011–2012, Chile) chall...

The initial phase of the 2021 Cumbre Vieja ridge eruption (Canary Islands): Products and dynamics controlling edifice growth and collapse (2022)
Journal Article
Romero, J. E., Burton, M., Cáceres, F., Taddeucci, J., Civico, R., Ricci, T., …Perez, N. M. (2022). The initial phase of the 2021 Cumbre Vieja ridge eruption (Canary Islands): Products and dynamics controlling edifice growth and collapse. Journal of Volcanology and Geothermal Research, 431, Article 107642. https://doi.org/10.1016/j.jvolgeores.2022.107642

Tajogaite cone in the Cumbre Vieja ridge (La Palma, Canary Islands) erupted between 19 September and 13 December 2021. The tephra and lava sourced from the newly formed fissure rapidly built a pyroclastic cone. During the early days of eruption and a...

Development, structure, and behavior of a perched lava channel at Kīlauea Volcano, Hawaiʻi, during 2007 (2022)
Journal Article
Orr, T. R., Llewellin, E. W., & Patrick, M. R. (2022). Development, structure, and behavior of a perched lava channel at Kīlauea Volcano, Hawaiʻi, during 2007. Journal of Volcanology and Geothermal Research, 430, Article 107637. https://doi.org/10.1016/j.jvolgeores.2022.107637

Channelized lava flows are commonly produced during the early stages of basaltic eruptions. These channels usually maintain their morphology until the eruption ends or discharge is diverted. In some instances, narrower channels can roof over, develop... Read More about Development, structure, and behavior of a perched lava channel at Kīlauea Volcano, Hawaiʻi, during 2007.

Bubble rise in molten glasses and silicate melts during heating and cooling cycles (2022)
Journal Article
Jackson, L. E., Wadsworth, F. B., Mitchell, J., Rennie, C., Llewellin, E. W., Hess, K., & Dingwell, D. B. (2022). Bubble rise in molten glasses and silicate melts during heating and cooling cycles. Journal of the American Ceramic Society, 105(12), 7238-7253. https://doi.org/10.1111/jace.18680

The Hadamard–Rybczynski equation describes the steady-state buoyant rise velocity of an unconfined spherical bubble in a viscous liquid. This solution has been experimentally validated for the case where the liquid viscosity is held constant. Here, w...

Dendritic crystallization in hydrous basaltic magmas controls magma mobility within the Earth’s crust (2022)
Journal Article
Arzilli, F., Polacci, M., La Spina, G., Le Gall, N., Llewellin, E. W., Brooker, R. A., …Burton, M. R. (2022). Dendritic crystallization in hydrous basaltic magmas controls magma mobility within the Earth’s crust. Nature Communications, 13(1), https://doi.org/10.1038/s41467-022-30890-8

The majority of basaltic magmas stall in the Earth’s crust as a result of the rheological evolution caused by crystallization during transport. However, the relationships between crystallinity, rheology and eruptibility remain uncertain because it is...

Crowd-sourcing observations of volcanic eruptions during the 2021 Fagradalsfjall and Cumbre Vieja events (2022)
Journal Article
Wadsworth, F. B., Llewellin, E. W., Farquharson, J. I., Gillies, J. K., Loisel, A., Frey, L., …Santabárbara, A. P. (2022). Crowd-sourcing observations of volcanic eruptions during the 2021 Fagradalsfjall and Cumbre Vieja events. Nature Communications, 13(1), https://doi.org/10.1038/s41467-022-30333-4

The Fagradalsfjall1 and Cumbre Vieja eruptions were spectacular and, in the case of Cumbre Vieja, highly destructive. Over their course, the eruptions waxed and waned, fed lava flows, caused numerous felt earthquakes and explosions, localized from cr...
