How fast does the lava move (down the tubes, over the land)?
Typically, lava moves very slowly in the coastal area of the park and
visitors can stand close to the front of the lava flow. Photo by Tom

Answer:
Lava in tubes moves about 3 feet/sec (1 m/sec) coming down the pali and
slower on the flat. On the surface, the lava typically moves a few
feet/minute (about a meter/minute) or even slower.
