Can the walls (skeleton) of a super adobe dome resist a lava flow without melting and collapsing?
It is an interesting question about the durability of earthbag construction in the path of a lava flow. I think it would depend on what the bags were filled with. As with any masonry material (like stone, concrete, bricks) earthbags that were filled with well-compacted and consolidated soil (like adobe or cement stabilized soil) should fair pretty well in these circumstances. Many people actually burn off the polypropylene bag material before plastering them, so obviously the bags are no longer essential to the integrity of the structure. But if the bags were filled with a looser material like gravel or sandy soil, and the bags were burned by the lava, then the structure might fail.
