Study of Subsurface Structures Northwest of Ascraeus Mons, Mars, Based on Variational Bayesian Monte Carlo

open access: yesIEEE Access
Tharsis Montes is the largest volcanic province on Mars, and Ascraeus Mons in its northeastern part is the largest volcano of the province. The material composition of the lava flows and lava plains to the northwest of Ascraeus Mons is important for the ...

Impact of Environmental Factors on the Spectral Characteristics of Lava Surfaces: Field Spectrometry of Basaltic Lava Flows on Tenerife, Canary Islands, Spain

open access: yesRemote Sensing, 2015
We report on spectral reflectance measurements of basaltic lava flows on Tenerife Island, Spain. Lava flow surfaces of different ages, surface roughness and elevations were systematically measured using a field spectroradiometer operating in the range of

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.

DOWNFLOW code and LIDAR technology for lava flow analysis and hazard assessment at Mount Etna

open access: yesAnnals of Geophysics, 2011
The use of a lava-flow simulation (DOWNFLOW) probabilistic code and airborne light detection and ranging (LIDAR) technology are combined to analyze the emplacement of compound lava flow fields at Mount Etna (Sicily, Italy).

Erosion versus construction: The origin of Venusian channels [PDF]

open access: yes
Lava channels are a common feature in the volcanic regions of the Moon, and have now been observed on Venus. There has been much debate about the origin of lunar channels as to whether they are the result of erosional (either thermal or mechanical) or ...

Spatiotemporal Modeling of Lava Dome Evolution of Mt. Mayon during its 2023 Eruption using Remote Sensing Data [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Numerous lava dome construction and destruction processes were observed during the 2023 Mayon Volcano activity from 08 June until 08 December. Studying the lava dome development cycle of active volcanoes similar to Mayon Volcano is crucial because ...

The 1984 Mauna Loa eruption and planetary geolgoy [PDF]

open access: yes
In planetary geology, lava flows on the Moon and Mars are commonly treated as relatively simple systems. Some of the complexities of actual lava flows are illustrated using the main flow system of the 1984 Mauna Loa eruption. The outline, brief narrative,

Toward a model for leveed lava flows [PDF]

open access: yes
Many lava flows have two distinct volumetric components during emplacement. First, there is a component actively flowing in accordance with Newtonian or other constitutive relations.

Studies of fluid instabilities in flows of lava and debris [PDF]

open access: yes
At least two instabilities have been identified and utilized in lava flow studies: surface folding and gravity instability. Both lead to the development of regularly spaced structures on the surfaces of lava flows. The geometry of surface folds have been

Relative ages of lava flows at Alba Patera, Mars [PDF]

open access: yes
Many large lava flows on the flanks of Alba Patera are astonishing in their volume and length. As a suite, these flows suggest tremendously voluminous and sustained eruptions, and provide dimensional boundary conditions typically a factor of 100 larger ...
