Hawaii's Ancient Sea Arch Crumbles into Ocean

Hawaii's famed Hōlei sea arch, a geological marvel that stood for over 550 years, has collapsed into the ocean. Located in the dramatic landscape of Volcanoes National Park on the Big Island, the arch was a testament to nature's power, formed by relentless ocean wave erosion.

Park officials confirmed the collapse occurred between Wednesday, September 23, 2026, and Sunday, September 27, 2026, following a series of severe storms. The arch's demise had been anticipated due to existing cracks and instability, exacerbated by the 2018 Kīlauea volcanic eruption and significant wave action from past tropical systems.

The Hawaiian islands have experienced an unusual number of severe storms recently, consistent with an active El Niño pattern. This intensified storm activity, potentially amplified by global warming, has impacted the region significantly, causing widespread disruption.

Scientists had long predicted the arch's eventual disappearance, noting the daily erosion from crashing waves. While its exact formation date is estimated around 550 years ago, the forces of nature have now claimed this ancient landmark.
