How Volcanoes Build New Land | Born from Fire | Mackinov

A glowing river of rock can become the ground beneath your feet. How do volcanoes build new land? This original Mackinov documentary follows magma, lava fountains, flowing channels, cooling crust, and ocean entries to explain how volcanic landscapes grow and keep changing. Historical examples from Kilauea, Hawaii, are shown from separate dates and eruptions; this is not a live report or a continuous record of one event.
