Basaltic lavas collected at the Muliwai a Pele lava channel, built during 1974 as part of Mauna Ulu’s eruption on Kilauea’s east rift zone, have been studied to investigate the effect of cooling and crystallization on the rheological properties of the lava. We have quantified the viscosity-strain-rate dependence of lava during cooling and crystallization, using concentric cylinder viscometry. We measured the viscosity of the crystal-free liquid between 1600 and 1230 °C, where we observed a… 
Rheology of lava flows on Mercury: An analog experimental study
We experimentally determined the rheological evolution of three basaltic analog compositions appropriate to Mercury's surface, during cooling, and crystallization. Investigated compositions are an
Field and experimental constraints on the rheology of arc basaltic lavas: the January 2014 Eruption of Pacaya (Guatemala)
We estimated the rheology of an active basaltic lava flow in the field, and compared it with experimental measurements carried out in the laboratory. In the field we mapped, sampled, and recorded
Experimental constraints on the rheology, eruption, and emplacement dynamics of analog lavas comparable to Mercury's northern volcanic plains
We present new viscosity measurements of a synthetic silicate system considered an analogue for the lava erupted on the surface of Mercury. In particular, we focus on the northern volcanic plains
Equilibrium Viscosity and Disequilibrium Rheology of a high Magnesium Basalt from Piton De La Fournaise volcano, La Reunion, Indian Ocean, France
Lava flows are a common hazard at basaltic to intermediate volcanoes in general and have posed a significant threat to La Reunion Island specifically over the past centuries. In sustained flow units,
An Extended Rheological Map of Pāhoehoe—‘A‘ā Transition
The pāhoehoe—‘a‘ā morphological transition involves a change in the rheological response of the magmatic suspension from pure viscous to complex rheological behavior, resulting in the development of
The viscosity of pāhoehoe lava: In situ syn-eruptive measurements from Kilauea, Hawaii
The viscosity of p ā hoehoe lava : in situ syn-eruptive 1 measurements from Kilauea , Hawaii 2 3
12 Viscosity is one of the most important physical properties controlling lava flow dynamics. 13 Usually, viscosity is measured in the laboratory where key parameters can be controlled but 14 can
Experimental constraints on the origin of pahoehoe “cicirara” lavas at Mt. Etna Volcano (Sicily, Italy)
We present results from phase equilibria experiments conducted on the most primitive pahoehoe “cicirara” trachybasaltic lava flow ever erupted at Mt. Etna Volcano. This lava is characterized by a


Rheology of arc dacite lavas: experimental determination at low strain rates
Andesitic–dacitic volcanoes exhibit a large variety of eruption styles, including explosive eruptions, endogenous and exogenous dome growth, and kilometer-long lava flows. The rheology of these lavas
Textural and rheological evolution of basalt flowing down a lava channel
The Muliwai a Pele lava channel was emplaced during the final stage of Mauna Ulu’s 1969–1974 eruption (Kilauea, Hawaii). The event was fountain-fed and lasted for around 50 h, during which time a
Cooling and crystallization of lava in open channels, and the transition of Pāhoehoe Lava to 'A'ā
Abstract Samples collected from a lava channel active at Kīlauea Volcano during May 1997 are used to constrain rates of lava cooling and crystallization during early stages of flow. Lava erupted at
Shear rate dependence of the pāhoehoe-to-‘a‘ā transition: Analog experiments
Hawaiian lava flows typically erupt as pahoehoe and transform to 'a'aas they travel away from eruptive vents, although the exact conditions that govern this transformation are not well constrained.
Geothermometry of Kilauea Iki lava lake, Hawaii
Data on the variation of temperature with time and in space are essential to a complete understanding of the crystallization history of basaltic magma in Kilauea Iki lava lake. Methods used to
Pahoehoe and aa in Hawaii: volumetric flow rate controls the lava structure
The historical records of Kilauea and Mauna Loa volcanoes reveal that the rough-surfaced variety of basalt lava called aa forms when lava flows at a high volumetric rate (>5–10 m3/s), and the
