Hawaii Volcanoes' Holei Sea Arch Falls Into Ocean
The National Park Service confirmed that the 90-foot Holei Sea Arch in Hawaii Volcanoes National Park collapsed into the Pacific, likely during Tropical Storm Nolo, and issued safety warnings for visitors. SFGATE reported that the natural lava formation had collapsed after years of erosion, and NBC News said the arch fell between late September and early October, likely accelerated by recent storm activity.
