You can expect the walls to give way from the load, and the heat in the lava is such that it burns everything in its path.« Apart from the heat, since it's molten rock it also has considerable mass, and the lava flow continues pushing from behind.
- jon_richards 3y agoOne weird realization I had is that lava is over three times as dense as water, so if you tired to “swim” in it, you’d basically just sit on top.

- ceejayoz 3y ago“Sit” might not be the right verb here.
- s1artibartfast 3y agoit is less about density and more about viscosity, which depends on the type and temperature. I had an opportunity to interact with lava during a Hawaii eruption, and people could run/walk across red hot and flowing lava, but it would start melting the bottom of your shoes. This lava was definitely on the colder end of the spectrum, with a consistency like bread dough. On the the other end of the specturm, there are very hot low viscosity lavas similar in consistency to soup. If you tried to step on that, it would be like falling into a pool.
- BenjiWiebe 3y agoYou'd only keep sinking in until you had displaced your mass in lava. Which would happen sooner than in water.

- sixothree 3y agoI'm not really sure what you mean by this. But I'm guessing that you really have no clue what would happen.
