Tohunga Volcano has a lava stream which goes all the way to the Tohunga Village, where the Tohunga use the lava for their benefit like heating. And they also cool some down, to make rock to carve. The smoke rising from the volcano can be seen all the way from Tohunga Village. Piraka's Base was built inside the volcano, because it was easy to attack Tohunga Village from there. Hakann loved the volcano and used to have his own lava pool in there.
