They suspect it may have happened while the park was temporarily closed during Tropical Storm Nolo.

RightThe New York Post reports that Nolo brought heavy rain and powerful winds to the Big Island, causing flash flooding and road closures, and that the park was closed for three days.

New York PostR “formed about 550 years ago as waves carved through an ancient lava flow” Read at New York Post ↗ Hindustan TimesN “more than 500 years after it was naturally formed” Read at Hindustan Times ↗ CentreThe Hindustan Times attributes the collapse to natural erosion: waves wore away softer rock faster than harder layers, a process called differential erosion that left the arch increasingly fragile. It says the NPS had long warned the arch would eventually crumble into the sea and that new formations would emerge as the cliff moves inland.

RightThe New York Post describes years of damage before the collapse. Earthquakes during the 2018 Kīlauea eruption and summit collapse damaged the surrounding cliffs. New cracks led the park to close the original viewing area in January 2020, and a safer viewing area farther from the edge opened that March. Later in 2020, surf from Tropical Storm Darby knocked rock loose from the arch's lower portion.

It says social media photos show people entering the closed area near where the arch stood, risking falls and drowning and endangering first responders. Hindustan TimesN “Photos on social media show people entering the closed area near where the sea arch once stood, putting themselves and first responders at great risk of falling and drowning” Read at Hindustan Times ↗ New York PostR “Visitors were warned to stay away from the site near Hōlei Sea Arch, where the cliffs drop straight into the Pacific and can collapse without warning.” Read at New York Post ↗ RightThe New York Post also quotes visitors who mourned the loss, including one who photographed the arch on 23 September at about 10 am and called themselves among the last to see it standing. New York PostR ““We were just there on Sept 23rd around 10 am and are probably some of the last few to see it still standing,” one visitor wrote on Facebook.” Read at New York Post ↗
