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

Nestled in the Keonjhar District of Odisha, the #Geoheritage site of Nomira Pillow Lava is a remarkable example of submarine volcanic activity from the Precambrian era. 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

LAVA TYPES Lava is molten rock that emerges from a volcano or fissure onto the Earth’s surface during volcanic eruptions. Depending on its chemical composition, temperature, and viscosity, lava can be classified into different types, which affect its flow behavior and eruption style. MAIN TYPES OF LAVA: 1. Pāhoehoe Lava (Ropy Lava): Appearance: Smooth, shiny, and ropy surface. Viscosity: Low (flows easily). Temperature: Higher than ‘A‘ā lava (~1100°C–1200°C). Behavior: Flows in thin sheets or ch
