A well-known sea arch on Hawaii’s Big Island, the Holei Sea Arch, collapses along a wave-swept stretch of coast, according to the National Park Service (NPS) and multiple reports.

The incident occurs in an area where NPS has ongoing concerns about coastal erosion and unstable cliffs. Following the collapse, officials warn visitors that additional rockfall and other hazards may occur because the cliffs are continuing to erode.

Across outlets, the central points remain consistent: the sea arch collapses, and the NPS uses the event to reinforce public safety guidance for the surrounding shoreline. The reporting focuses on the same location and the same type of risk—hazards tied to unstable, eroding coastal conditions—rather than on differing interpretations or causes beyond the general instability of the cliffs.
