HAWAII: The historic Holei Sea Arch in Hawaii has collapsed into the Pacific Ocean more than 500 years after its natural formation.
The towering rock formation stood about 27 metres high in Hawaii Volcanoes National Park, on one of the largest and youngest islands in the Hawaiian chain.
According to the United States National Park Service (NPS), the arch formed around 550 years ago when molten lava from a volcanic eruption flowed towards the coast.
The lava met coastal cliffs and gradually shaped the rock into a natural arch. The formation attracted visitors for many years.
NPS Says Sea Arch Was Always Temporary
The NPS described the sea arch as a beautiful but temporary natural feature.
It said such formations eventually collapse into the sea, while new arches may emerge as coastal cliffs gradually move inland.
The agency explained that selective erosion determines the lifespan of these cliffs and formations.
Although park staff knew that powerful waves would eventually weaken the arch, they could not predict exactly when it would collapse.
Park Urges Visitors to Stay Safe
Hawaii Volcanoes National Park urged visitors to avoid putting themselves in danger.
The collapse marks the loss of a long-standing coastal landmark, while highlighting the ongoing changes caused by waves and erosion along Hawaii’s volcanic coastline.
