These bulbous lava formations offer a rare glimpse into ancient underwater eruptions — a true geological marvel and a must-visit for geotourism enthusiasts. #NomiraPillowLava #Odisha #IncredibleIndia #Geotourism #GSI | Geological Survey of India | Facebook

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

In Odisha are the Pillow Lava formations which are formed about 2500 million years ago, is one of the geo-heritage sites found in Nomira in Keonjhar. It’s an exposure of well-preserved pillow lava structures. They are formed when hot molten lava erupts under water and solidifies in the form of roughly spherical or rounded pillow-shape.

Most people think volcanoes only exist on land, but over 75% of all volcanic activity happens underwater—hidden in the deep ocean. These seafloor giants are called submarine volcanoes, and some are taller than Mount Everest. Because of extreme pressure at depth, many eruptions happen silently, without the explosive blasts we see on land. Instead, molten lava oozes out, instantly chilling into pillow-shaped rocks. Some underwater eruptions can release superheated water over 400°C (750°F), creatin
