Quick Summary

The Holei Sea Arch, an iconic 90-foot lava rock arch in Hawaii Volcanoes National Park on the Big Island, has collapsed into the Pacific Ocean. The collapse occurred around late September during Tropical Storm Nolo, which brought heavy rain and strong winds to the area. The park service posted before-and-after photos of the site on social media, noting its temporary nature due to erosion by sea waves over centuries. The storm's impact coincided with the arch’s natural deterioration, leading to its sudden disappearance, prompting both sadness from visitors and reminders about the impermanence of such geological formations.

Story summary

The Hōlei Sea Arch, a 550-year-old lava rock formation standing at approximately 90 feet tall in Hawaii Volcanoes National Park on the Big Island, collapsed into the Pacific Ocean sometime between September 23 and September 27, likely during Tropical Storm Nolo. The arch was still visible as of September 23 but had disappeared by September 27 when the park reopened. This collapse marks a significant loss to the region's natural wonders and tourist attractions, with thousands of people expressing grief on social media platforms like Facebook and Google Maps marking it as "permanently closed." Despite its beauty, experts warned that the arch's instability was anticipated due to ongoing erosion from waves and earthquakes caused by the 2018 Kīlauea volcano eruption. The National Park Service has issued warnings about unstable cliffs near the former site of the sea arch, urging visitors to stay back for safety reasons.

Narrative

For more than half a millennium, one of Hawaii’s most cherished geological marvels, an arch 90 feet (about 27m) high composed of lava rock, withstood a battering from the Pacific and evoked a sense of awe. But that formation, the Holei Sea Arch at Hawai’i Volcanoes National Park, is now gone from the coastline on the Big Island, having crumbled into the ocean around the same time as a tropical storm brought strong winds and heavy rain to Hawaii in late September, the National Park Service said on Oct 1.
