The influence of water-saturation on the strength of volcanic rocks and the stability of lava domes
Marie Estelle Solange Violay, Michael Heap
The rocks forming a volcanic edifice or dome are typically saturated or partially-saturated with water. However, most experiments aimed at better understanding the mechanical behaviour of volcanic rocks have been performed on dry samples, and therefore mos ...
2023Permeability, alteration, and microstructure: A (hopefully) coupled rock physics and geochemical approach to how rock-fluid interactions change permeability
Permeability is a key physical property across all spatial scales in the Earth’s crust and exerts significant control on the behaviour of Earth systems, with implications for natural hazards (e.g., earthquakes, slope instabilities, volcanic eruptions) and ...
2023Taking the pulse of volcanic eruptions using plagioclase glomerocrysts
Anders Meibom, Stéphane Laurent Escrig, Anders McCarthy, Pierre Vonlanthen
Crystallization timescales in subvolcanic systems and the consequences of interaction between ascending magmas and gases remain largely unconstrained, as do links between these processes and monitoring signals at restless volcanoes. We apply diffusion chro ...
ELSEVIER2020Plagioclase Glomerocrysts: taking the pulse of volcanic eruptions
Anders Meibom, Stéphane Laurent Escrig, Anders McCarthy
Volcanic eruptions result from complex interplay of magmatic processes including the ascent and storage of magma in the crust, volatile exsolution and crystallization. The dynamics of crystallization in shallow subvolcanic systems and the consequences of i ...
2019Variation of Ice Nucleating Particles in the European Arctic Over the Last Centuries
Julia Schmale, Arne Christian Vogel
The historical development of ice nucleating particle concentrations (NINP) is still unknown. Here, we present for the first time NINP from the past 500 years at two Arctic sites derived from ice core samples. The samples originate from the EUROCORE ice co ...
2019Short magmatic residence times of quartz phenocrysts in Patagonian rhyolites associated with Gondwana breakup
Anders Meibom, Stéphane Laurent Escrig, Lukas Baumgartner, Susanne Seitz
A key parameter in the study of magma evolution is the time scale on which magmatic processes occur. Using nanoscale secondary ion mass spectrometry (NanoSIMS), SIMS, and cathodoluminescence (CL) analyses, we have measured titanium (Ti) diffusion profiles ...
Geological Society of America2016Ductile flow in sub-volcanic carbonate basement as the main control for edifice stability: New experimental insights
Limestone in volcanic basements has been identified as a hazard in terms of edifice stability due to the propensity of calcite to decompose into lime and CO2 at high temperatures (>600 °C), causing a decrease in mechanical strength. To date, such hypoth ...
Elsevier2015Dike emplacement at Bardarbunga, Iceland, induces unusual stress changes, caldera deformation, and earthquakes
A 45-km-long regional dike was emplaced over a period of 2 weeks in August 2014 at the boundary between the East and North Volcanic Zones in Iceland. This is the first regional dike emplacement in Iceland monitored with modern geophysical networks, the imp ...
Springer Verlag2014A new model for TBM performance prediction in blocky rock conditions
The term "blocky rock conditions" is generally associated with face instabilities in blocky/jointed rock masses. These events are generally promoted by unfavorable rock mass structural conditions, in terms of joint frequency and orientation, and acting str ...
Pergamon-Elsevier Science Ltd2014On the relationship between total ozone and atmospheric dynamics and chemistry at mid-latitudes - Part 2: The effects of the El Nino/Southern Oscillation, volcanic eruptions and contributions of atmospheric dynamics and chemistry to long-term total ozone changes
Anthony Christopher Davison, Linda Frossard
We present the first spatial analysis of "fingerprints" of the El Nino/Southern Oscillation (ENSO) and atmospheric aerosol load after major volcanic eruptions (El Chichon and Mt. Pinatubo) in extreme low and high (termed ELOs and EHOs, respectively) and me ...
