Comparison of Microbial Diversity of Two Typical Volcanic Soils in Wudalianchi, China

Microorganisms
Volcanic lava is an excellent model of primary succession, in which basalt-associated microorganisms drive the cycling of different elements such as nitrogen, carbon, and other nutrients. Microbial communities in volcanic soils are of particular interest

Thermal impacts of basaltic lava flows to buried infrastructure: workflow to determine the hazard

Journal of Applied Volcanology, 2020
Lava flows can cause substantial physical damage to elements of the built environment. Often, lava flow impacts are assumed to be binary, i.e. cause complete damage if the lava flow and asset are in contact, or no damage if there is no direct contact ...

Models of Hawaiian volcano growth and plume structure: Implications of results from the Hawaii Scientific Drilling Project [PDF]

, 1996
The shapes of typical Hawaiian volcanoes are simply parameterized, and a relationship is derived for the dependence of lava accumulation rates on volcano volume and volumetric growth rate.

Source(s) of the Smooth Caloris Exterior Plains on Mercury: Mapping, Remote Analyses, and Scenarios for Future Testing with BepiColombo Data

Remote Sensing
Mercury hosts widespread smooth plains that are concentrated in the Caloris impact basin, in an annulus surrounding the Caloris basin, and in the adjacent northern smooth plains.

Tube coalescence in the Jingfudong lava tube and implications for lava flow hazard of Tengchong volcanism

International Journal of Speleology, 2016
Tube-fed structure occurs as a general phenomenon in Tengchong basic lavas, such as lava tubes, lava plugs and tube-related collapse depressions. We deduced the development of Laoguipo lava flows, which is the longest lava tube (Jingfudong lava tube ...

Impact vesiculation – a new trigger for volcanic bubble growth and degassing [PDF]

, 2007
We highlight a potentially important trigger for bubble growth and degassing in volcanic bombs. We have successfully triggered bubble growth in previously unvesiculated samples of silicate melt during experiments to simulate volcanic bomb impact, by ...

Thermal structure of a gas-permeable lava dome and timescale separation in its response to perturbation [PDF]

, 2009
The thermal boundary layer at the surface of a volcanic lava dome is investigated through a continuum model of the thermodynamic advection diffusion processes resulting from magmatic gas flow through the dome matrix.
