Hawaii’s centuries-old sea arch collapses into Pacific after series of rough storms
It was naturally formed around 550 years ago due to differential erosion by ocean waves.The exact timing of the collapse is unknown. Every day the ocean crashes against the pillar of the arch, eroding it a little more. Then, in January 2020, new cracks and instability prompted the park to close the original viewing area and open a safer one further from the cliff edge three months later.
