Mariner 9 photographs of small-scale volcanic structures on Mars [PDF]

open access: yes
Surface features on the flanks of Martian shield volcanoes photographed by Mariner 9 are identified as lava flow channels, rift zones, and partly collapsed lava tubes by comparisons with similar structures on the flanks of Mauna Loa shield volcano ...

Surface Textures and Features Indicative of Endogenous Growth at the McCartys Flow Field, NM, as an Analog to Martian Volcanic Plains [PDF]

open access: yes, 2012
Basaltic lavas typically form channels or tubes, which are recognized on the Earth and Mars. Although largely unrecognized in the planetary community, terrestrial inflated sheet flows also display morphologies that share many commonalities with lava ...

New Insights into Lava Tube Formation: An Asymmetrical and Deep Case Observed by Yutu-2 Radar at Lunar Farside

open access: yesThe Astrophysical Journal
This article reports a potential lava tube observed at ∼130 m depth of the lunar farside by Lunar Penetrating Radar data. However, a possible scenario with a kind of dry and low-density materials connected with a basaltic boulder or lava flow cannot be ...

Extensive lava flow fields on Venus: Preliminary investigation of source elevation and regional slope variations [PDF]

open access: yes
Large-volume lava flow fields have been identified on Venus, the most areally extensive of which are known as fluctus and have been subdivided into six morphologic types.

From Hurricane Irma to the Grindavík eruptions: volatility premiums in disaster governance

open access: yesDisasters, Volume 50, Issue 2, April 2026.
Abstract Environmental volatility can inflate property values even as it destroys them. To show how, this article pairs a postcolonial micro‐state in the Caribbean (Sint Maarten after Hurricane Irma) with a Nordic welfare town (Grindavík in Iceland following volcanic eruptions) because they occupy the opposite ends of the governance capacity spectrum ...

Trace Element Emissions Vary With Lava Flow Age and Thermal Evolution During the Fagradalsfjall 2021–2023 Eruptions, Iceland

open access: yesGeochemistry, Geophysics, Geosystems
Basaltic fissure eruptions emit volatile and environmentally reactive gases and particulate matter (PM) into the lower troposphere (e.g., SO2, HCl, and HF in the gas phase; Se, As, Pb as complexes in the PM phase).

SPH Simulation of Molten Metal Flow Modeling Lava Flow Phenomena with Solidification

open access: yesDynamics
Characteristic dynamics in lava flows, such as the formation processes of lava levees, toe-like tips, and overlapped structures, were reproduced successfully through numerical simulation using the smoothed particle hydrodynamics (SPH) method. Since these

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 ...
