🟣🟢 Fun Fact Friday 🟢🟣
🌋🌊 The underwater geology of Hawaii is truly astonishing!
The Hawaiian Islands are just the visible peaks of a massive chain of volcanoes rising from the floor of the Pacific Ocean. What we see above sea level represents only a small portion of these enormous volcanic mountains.
🏔️ Mauna Kea, on Hawaii’s largest island, stands 4,207 meters (13,803 ft) above sea level. However, when measured from its base on the ocean floor, it rises more than 10,000 meters (33,000 ft), making it taller from base to summit than Mount Everest.
🌋 Hawaii was formed by a volcanic hotspot beneath the Pacific Plate. As the plate slowly moves northwest, new volcanoes emerge while older islands gradually erode and sink. This process has created the Hawaiian–Emperor Seamount Chain, which stretches thousands of kilometers across the Pacific Ocean.
🌊 The image reveals a fascinating reality: the islands are merely the tops of gigantic underwater volcanoes. Beneath the surface lies a dramatic landscape of steep volcanic slopes, submerged ridges, and ancient seamounts hidden deep beneath the ocean.
🔥 Hawaii is still growing today. An active submarine volcano southeast of the Big Island, known as Kamaʻehuakanaloa (formerly Loʻihi), is slowly building upward and could someday become a new Hawaiian island.
💡 Fun fact: If mountains were measured from their true base rather than from sea level, Mauna Kea would be considered the tallest mountain on Earth. 🌎🏔️
