LAVA • PIPES • AMAZING
Lava tubes - are natural conduits through which lava rises from the earth to the surface. They usually appear during a volcanic eruption, and can be both active and dormant - when the lava flow stopped, and the pipe has cooled down, then left cavernous tunnels. Lava tubes - a kind of lava cave formed when an active lava flow develops a hard crust of the earth, which condenses and forms a roof over the still ongoing "stream" of lava. , Lava tubes may be up to 14-15 m in width, although they are often much longer and extend from 1 to 15 m underground. The tubes may be very long. For example, the Mauna Loa lava tube enters the ocean about 50 km from the point of eruption. We bring you the 12 most beautiful lava tubes in the world. Just imagine how it flowed along the mighty hot lava!
