The iconic Hōlei Sea Arch in Hawaiʻi Volcanoes National Park collapsed into the Pacific Ocean, potentially during the park’s closure due to Tropical Storm Nolo on September 27, 2026. The arch, a 90-foot lava rock formation that had stood for 550 years, was shaped by the relentless waves of the Pacific Ocean eroding an ancient lava flow. This natural landmark was named after a small endemic plant and was well-loved by visitors.
Hōlei Sea Arch’s collapse was likely exacerbated by environmental factors, including the 2018 Kilauea eruption, which had already weakened the cliffs, and the intense weather associated with Hurricane Nolo, which brought heavy rainfall to the region. This event serves as a reminder of the transient beauty of natural formations, as others will eventually take their place along the coastline. The National Park Service encourages sharing memories and photos of the arch in its wake.
