  • Volcano-footage: best video shots of volcanoes and volcanic eruptions

    12,166 views 3 years ago
    This volcano footage shows spectacular video shots of erupting volcanoes like Bromo, Etna, Nyiragongo, Sinabung and Stromboli.
    In 1990, I climbed for the first time an active volcano. That was Stromboli on the Aeolian Islands. Since then I have been studying the volcanoes of the world and documenting their eruptions. I have several hundreds volcano videos in my stock footage.

    Volcanoes are openings in the earth's crust from which lava and gases escape. The lava accumulates during a volcanic eruption around the opening, and builds a volcano. The volcanic edifice can take very different forms. What kind of volcano emerges depends on the type of lava and some other factors, like the place of occurrence and eruption behaviour. The magma type determines how a volcano erupts.
    A distinction is made between magma and lava. Magma is the molten rock in the earth crust before it erupts on a volcano. Magma contains a lot of gases. The gases escape during the volcanic eruption. The degassed magma is then called lava.The lava solidifies after it was erupted from the volcano. It forms volcanic rocks that make up the volcanoes.

    Most volcanoes form along the continental margins and along the plate boundaries around the Pacific Ocean. This region is therefore referred to as the "Ring of Fire". Many volcanoes extend along divergent plate boundaries such as the mid-ocean ridges. Volcanoes also occur along continental fault zones such as the East African Rift Valley. There are also "hot spot" volcanoes such as Hawaii and Yellowstone which are formed by mantle plumes that rise from the core-mantle boundary.
