Hawaii's Iconic Hōlei Sea Arch Collapses into the Pacific
The 90-foot natural rock formation, a landmark in Hawaii Volcanoes National Park for over 500 years, disappeared into the ocean between September 23 and September 27.
Hawaii's famed Hōlei Sea Arch has collapsed into the Pacific Ocean after standing for more than 500 years. The 90-foot natural rock formation, located on the Big Island within Hawaii Volcanoes National Park, was last reported missing between September 23 and September 27, according to the National Park Service.
Authorities believe the arch likely crumbled and fell into the ocean during the three days the park was temporarily closed due to Tropical Storm Nolo. This occurred just days after tourists had been photographed at the site.
Park authorities have cautioned the public to avoid the area surrounding the former Hōlei Sea Arch due to the unstable ocean cliffs, which are susceptible to sudden collapses. Despite these warnings, social media posts have shown individuals trespassing in restricted zones near the former landmark, a dangerous act that poses risks to themselves and potential first responders.
The Hōlei Sea Arch was formed approximately 550 years ago through wave action that sculpted ancient lava. Years of erosion from turbulent surf, earthquake vibrations, and developing cracks contributed to its eventual downfall. The arch had sustained significant damage during the 2018 Kīlauea eruption and summit collapse, leading Hawaii Volcanoes National Park to close its viewing platform in January 2020 due to safety concerns. The site reopened two months later.
In 2020, strong waves from Tropical Storm Darby broke off a section near the base of the arch. Visitors expressed their surprise and nostalgia on social media, with one user commenting on a Facebook video of the arch, "The Epic Holei Sea Arch is no more… I guess the Park’s gonna have to change their signage and let people know it’s gone."
Another visitor noted, "Was there literally the day after it collapsed. Walked up and was like, wait, what am I supposed to be looking at there’s no arch here." A third individual shared, "It was a beautiful feature and one all of us was expecting to collapse since 2018. It’s crazy that it’s gone and finally gave way to the power of the ocean. Cheers to the arch and the lifetime of memories it gave everyone."
