## Hōlei Sea Arch Collapse
Hawaii's 550-year-old Hōlei Sea Arch collapsed into the Pacific Ocean after centuries of wave erosion.
## Arch's Location and Age
The 90-foot arch stood along Hawaiʻi Volcanoes National Park's coastline, carved from lava flow around 550 years ago.
## Collapse Timeline
The National Park Service confirmed the arch was standing on September 23 but disappeared by September 27, 2026.
## Erosion Process
Waves gradually eroded the arch through differential erosion, with the US Geological Survey warning it would disappear daily over a decade.
## Recent Instability
Earthquakes during Kīlauea's 2018 eruption damaged nearby cliffs, forcing park closures in January 2020.
## Current Warning
Park officials warn visitors not to approach the site after photos showed people entering the closed area where Hōlei once stood.
## Key takeaway

Hawaii's 550-year-old Hōlei Sea Arch collapsed into the Pacific Ocean due to wave erosion.
