Collapse of Hawai’i’s Hōlei Sea Arch Amidst Storms

The scenic Hōlei Sea Arch on Hawaii’s Big Island coast collapsed, as confirmed by the National Park Service. This collapse occurred in the Hawaii Volcanoes National Park between September 23 and September 27, likely during a temporary park closure because of Tropical Storm Nolo.

The park authorities stated, “The exact time of the collapse is unknown and could have occurred when the park was temporarily closed during Tropical Storm Nolo.” This storm brought 155 mph winds, impacting Hawaii’s Big Island with significant rain and strong winds.

In response to the storm, Hawaii Governor Josh Green announced that the Trump administration approved an emergency declaration, allowing federal aid for Hawaii’s recovery. Photographs from the USGS depict the Hōlei Sea Arch as it appeared in 2022 and after its collapse into the Pacific Ocean on September 27, 2026.

In August, the region faced Tropical Storm Lala, which caused substantial damage, including the destruction of approximately 100 homes and widespread power outages. These recent events are shaping the park’s constantly changing rugged coastline.

The National Park Service commented, “This formation is beautiful, but temporary, and has a limited life span.” Reactions to these events noted the natural course of change. Nevertheless, officials cautioned visitors against approaching the site due to the instability and danger it poses to those nearby.

There have been reports of people venturing into the closed area, risking falling or drowning. Officials stressed the seriousness of these hazards.

The Hōlei Sea Arch, a popular site, formed roughly 550 years ago. It derives its name from a native milkweed family plant. The evolving conditions of this coastline highlight both natural beauty and transformation.
