## The story

A 90‑foot cliff known as Holei Sea Arch in Hawaii Volcanoes National Park fell between September 23 and 27, 2026, during a period when the park was briefly closed for Tropical Storm Nolo.  The collapse, which sent the arch into the Pacific Ocean, was not unexpected but marks another change to the park’s rugged coastline.  Park officials warned that the area is unstable and poses a serious falling hazard, urging visitors to stay away.  Social media posts showed people entering the closed zone near the former arch, putting themselves and first responders at risk of falling and drowning.  The collapse underscores the dynamic nature of the island’s geology and the importance of respecting park safety notices.
