#lavaboat — Public Fediverse posts

Spotted yesterday at #MaunaLoa – a lava boat rides the waves! On Dec 7, a lava boat was spotted floating down channel. Lava boats can form when portions of the cone or lava channel break away & are rafted downstream. Hot lava cools to its surface to create that smooth exterior."

Look at the banks of the lava river, you can see some movement!

Nice shot of Mauna Kea in the background.

Question:
"It's buoyant because of vesiculation?"

Answer:
"Probably! It's also difficult for cooled lava to sink into molten lava, since they're so close in density. Someone would have to shove it down, and we imagine no one would want to stand that close..."
