Hawaii's 550-year-old Hōlei Sea Arch collapses into Pacific

Hawaii's iconic 90-foot Hōlei Sea Arch, a natural lava formation roughly 550 years old, has collapsed into the Pacific Ocean. The structure was confirmed standing on September 23 but was gone by September 27, 2026, during a park closure for Tropical Storm Nolo. Officials attribute the loss to long-term differential erosion and damage from the 2018 Kīlauea eruption.

Hawaii's 550-Year-Old Hōlei Sea Arch Collapses After Tropical Storm

The Hōlei Sea Arch, a 90-foot landmark in Hawaii's Volcanoes National Park, collapsed into the Pacific Ocean between September 23 and 28, 2026. Formed 550 years ago by lava flows, the structure fell due to differential erosion, a process park officials had long predicted would eventually destroy the arch. The collapse occurred during a closure for Tropical Storm Nolo, with the structure confirmed standing on September 23 but missing when the park reopened on September 28.
