Holei Sea Arch Collapses into Pacific Ocean at Hawaii Volcanoes National Park
Just the facts
The 90-foot-tall Holei Sea Arch located within Hawaii Volcanoes National Park collapsed into the Pacific Ocean after intense storms battered the Hawaiian coastline. National park authorities reported that heavy surf and ongoing coastal erosion compromised the basalt formation's structural stability before it gave way. The natural arch was formed through centuries of wave action cutting into hardened lava flows along the southern coast of Hawaii's Big Island. Park officials continue to monitor surrounding coastal cliffs for instability resulting from wave exposure and regional seismic activity.
