@nautiluslive: Our 2022 “#yellowbrickroad” video is making the rounds in the news cycle again, so we wanted to share the real story behind this fascinating #geological feature spotted while diving in #PapahānaumokuakeaMarineNationalMonument in 2022. This fractured flow of #hyaloclastite rock happens during high-energy #eruptions, where many rock fragments settle on the #seabed. The unique 90-degree fractures that resemble bricks are likely caused by heating and cooling stress from multiple eruptions at this baked margin. #Atlantis #RoadtoAtlantis #Nautiluslive #oceanexploration #oceanscience #marinegeology #geology
