Hawaii's 90-foot Holei Sea Arch collapses into the Pacific, the National Park Service confirms

1 October 2026

The United States National Park Service confirmed that the Holei Sea Arch in Hawaii Volcanoes National Park has collapsed into the Pacific Ocean.
The 90-foot arch was still standing on Wednesday 23 September and had collapsed by Sunday night 27 September.
The exact time of the collapse is unknown and it could have occurred while the park was temporarily closed during Tropical Storm Nolo.
Seismic activity from the 2018 Kilauea eruption had damaged the nearby cliffs.
New cracks prompted the closure of the original viewing area in January 2020, and surf from Tropical Storm Darby later broke off a chunk of rock from the lower part of the arch.
The park service warned that cliff edges in the area are unstable and can collapse without warning.
