ELEMENTAL AND TOPOGRAPHIC MAPPING OF LAVA FLOWSTRUCTURES IN MARE SERENITATIS ON THE MOON [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
The detection of lunar lava flows based on local morphology highly depends on the available images. The thickness of lava flows, however, has been studied by many researchers and lunar lava flows are shown to be as thick as 200 m.

Detailed Mapping of Lava and Ash Deposits at Indonesian Volcanoes by Means of VHR PlanetScope Change Detection

open access: yesRemote Sensing, 2022
Mapping of lava flows in unvegetated areas of active volcanoes using optical satellite data is challenging due to spectral similarities of volcanic deposits and the surrounding background.

The Estimation of Lava Flow Temperatures Using Landsat Night-Time Images: Case Studies from Eruptions of Mt. Etna and Stromboli (Sicily, Italy), Kīlauea (Hawaii Island), and Eyjafjallajökull and Holuhraun (Iceland)

open access: yesRemote Sensing, 2020
Using satellite-based remote sensing to investigate volcanic eruptions is a common approach for preliminary research, chiefly because a great amount of freely available data can be effectively accessed.

Detrital zircon and apatite (U‐Th)/He geochronology of intercalated baked sediments: a new approach to dating young basalt flows [PDF]

open access: yes, 2011
Simple numerical models suggest that many basaltic lava flows should sufficiently heat the sediments beneath them to reset (U‐Th)/He systematics in detrital zircon and apatite.

The genesis of a lava cave in the Deccan Volcanic Province (Maharashtra, India)

open access: yesInternational Journal of Speleology, 2016
Lava tubes and channels forming lava distributaries have been recognized from different parts of western Deccan Volcanic Province (DVP). Openings of smaller dimension have been documented from the pāhoehoe flows around Pune, in the western DVP.

Textural Insights Into the Evolving Lava Dome Cycles at Santiaguito Lava Dome, Guatemala

open access: yesFrontiers in Earth Science, 2018
The structures and textures preserved in lava domes reflect underlying magmatic and eruptive processes, and may provide evidence of how eruptions initiate and evolve. This study explores the remarkable cycles in lava extrusion style produced between 1922

Preliminary assessment for the use of VORIS as a tool for rapid lava flow simulation at Goma Volcano Observatory, Democratic Republic of the Congo [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2015
Assessment and management of volcanic risk are important scientific, economic, and political issues, especially in densely populated areas threatened by volcanoes. The Virunga volcanic province in the Democratic Republic of the Congo, with over 1 million

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 ...

Imagining and constraining ferrovolcanic eruptions and landscapes through large-scale experiments

open access: yesNature Communications, 2021
Ferrovolcanism is a hypothetical form of planetary volcanism in which the erupted lava is metallic in composition. Here we show that ferrovolcanic lava is denser and less viscous than silicate lava, resulting in fast-moving, thin, braided flows.

The 1998 eruption of Axial Seamount: New insights on submarine lava flow emplacement from high‐resolution mapping

open access: yesGeochemistry, Geophysics, Geosystems, 2013
Axial Seamount, an active submarine volcano on the Juan de Fuca Ridge at 46°N, 130°W, erupted in January 1998 along 11 km of its upper south rift zone.
