Emplacing a Cooling-Limited Rhyolite Lava Flow: Similarities with Basaltic Lava Flows [PDF]

open access: yesFrontiers in Earth Science, 2017
Accurate forecasts of lava flow length rely on estimates of eruption and magma properties and, potentially more challengingly, on an understanding of the relative influence of characteristics such as the apparent viscosity, the yield strength of the flow

Assessing impending hazards from summit eruptions: the new probabilistic map for lava flow inundation at Mt. Etna [PDF]

open access: yesScientific Reports, 2023
The development of probabilistic maps associated with lava flow inundation is essential to assess hazard in open vent volcanoes, especially those that have highly urbanized flanks.

Oceanic upper crustal accretion by melt sill and lava flow interaction at Axial volcano [PDF]

open access: yesNature Communications
Magmatically-accreted upper crust along mid-ocean ridges is traditionally considered to consist of lava flows overlying a sheeted-dyke complex. However, how the upper crust is formed at hotspot-influenced ridge segments remains unknown.

Local adaptation does not lead to genome‐wide differentiation in lava flow lizards [PDF]

open access: yesEcology and Evolution, 2019
Adaptation can occur with or without genome‐wide differentiation. If adaptive loci are linked to traits involved in reproductive isolation, genome‐wide divergence is likely, and speciation is possible.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Complex lava tube networks developed within the 1792–93 lava flow field on Mount Etna (Italy): insights for hazard assessment

open access: yesFrontiers in Earth Science
Lava tubes are powerful heat insulators, allowing lava to practically keep the initial temperature and travel longer distances than when freely flowing on the ground surface.

Lava effusion in mountainous terrain generates flow backup and excess inundation [PDF]

open access: yesCommunications Earth & Environment
Most volcanic eruptions occur in high-relief terrains, however the impact of mountainous topography on lava emplacement is poorly constrained. Here we use analogue materials (syrup, glycerol) to investigate lava effusion where changes in channel width ...

Satellite and Ground Remote Sensing Techniques to Trace the Hidden Growth of a Lava Flow Field: The 2014–2015 Effusive Eruption at Fogo Volcano (Cape Verde) [PDF]

open access: yesRemote Sensing, 2018
Fogo volcano erupted in 2014–2015 producing an extensive lava flow field in the summit caldera that destroyed two villages, Portela and Bangaeira.

Lava flow hazard map of Piton de la Fournaise volcano [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2021
Piton de la Fournaise, situated on La Réunion island (France), is one of the most active hot spot basaltic shield volcanoes worldwide, experiencing at least two eruptions per year since the establishment of the volcanological observatory in 1979 ...

Lava flow hazard at Fogo Volcano, Cabo Verde, before and after the 2014–2015 eruption [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2016
Lava flow simulations help to better understand volcanic hazards and may assist emergency preparedness at active volcanoes. We demonstrate that at Fogo Volcano, Cabo Verde, such simulations can explain the 2014–2015 lava flow crisis and therefore ...
