Volcano Tornado!


Stephen & Donna O’Meara explain the chaos in above photograph: “As the hot eruption cloud swirls, a vortex is created that spins off rare volcanic cyclones. As red rivers of lava pour into the Pacific Ocean from Hawaii’s Kilauea Volcano, huge explosions blast fragments of hot lava and cinder upwards 1,000 feet or more. These pieces of fragmented lava are called tephra –the booming tephra explosions create arcs of color during long exposures. During the daylight hours the hot lava looks black. As sun goes down it begins to glow red and a vast steam clouds form as it meets with ocean water.”
