What does lava look like after it has cooled underwater? Well, it looks like this. These pillow lavas were imaged in 2017 (#TBT!) at Vailulu'u Seamount, within National Marine Sanctuary of American Samoa. Scientists think the lava flows are likely less than five years old, meaning they are pretty young (geologically speaking). The lava erupted and was instantly cooled by the chilly seawater — creating a snapshot in time. Learn more here: https://oceanexplorer.noaa.gov/okeanos/explorations/ex1702

Pillow Lava is formed when hot molten lava erupts under water and solidifies in the form of roughly spherical or rounded pillow-shape. Pillow Lava, Maradihalli, Karnataka, is one of the best of its kind in the world.
