The story, neutrally told

MixedThe Hōlei Sea Arch, a roughly 90-foot (27-metre) formation in Hawaiʻi Volcanoes National Park on the Big Island, has collapsed into the Pacific Ocean. MixedThe arch was still standing on 23 September but was gone by the night of 27 September, according to the National Park Service (NPS). MixedOfficials do not know exactly when it fell. 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. MixedBoth outlets say the arch was about 500 years old; the New York Post adds that it formed about 550 years ago, when waves carved through an ancient lava flow at the end of Chain of Craters Road. 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. MixedThe NPS is urging visitors to stay away from the area and other unstable coastal cliffs. It says social media photos show people entering the closed area near where the arch stood, risking falls and drowning and endangering first responders. 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.

Every sentence links to the reporting it rests on. The pill in front of each says where its sources sit: Left, Centre or Right when one side supplies at least half of them, Mixed when they are evenly split.
