Lava

“Lava Rises From the Deep”

“The Big Island of Hawaii rises 33,474 feet above the floor of the Pacific Ocean and lies over an unusually warm part of the Earth’s interior. This hot spot has produced the volcanoes that make up the Hawaiian archipelago. The three most recently active volcanoes—Kilauea, Mauna Loa and Loihi—rise out of the spot. Other, less-active and dormant volcanoes in the archipelago used to lie here as well, but the natural movement of the Pacific tectonic plate has carried them away to the northwest. This unusually detailed image was taken primarily in the infrared spectrum, allowing us to see the volcanoes’ hidden underwater bases.”
