There have been reports of some localised fumarole activity during the past 100 years, and a new lava flow broke out only 20 years ago.
For lava, the dome is unlikely to be vertically isothermal because the diffusivity is small.
Geologically, the only reasonable conclusion is that the lavas were erupted subaerially, or perhaps emplaced as sills close to the surface in some cases.
The writer merges memory with botanical and geological discoveries and investigation, family lore with descriptions of lava flows, poetry and the narrative essay.
These conglomerates are composed of clasts of basalt, volcaniclastic sandstone, alkaline lava and sub-rounded chert.
Given the relative efficiency of convection compared to conduction, this stage would probably be short compared with the time it takes the lava to freeze.
It is important to note that our model assumes that the lava was erupted in an isothermal state at its melting temperature.
And where would we place fire and smoke, not to mention liquids of all kinds from ink to volcanic lava?
