as a result of heavy storms.
There has been concern this could happen.
Images taken from the coast today show not only that the arch has given way, but also the stacks either side of it.
In 2013, a geological study found that while erosion was inevitable, there was no imminent danger of the structure collapsing.

Yes, the global climate is changing, but Earth is a dynamic planet: has been for billions of years, and will continue to be so long after humans are gone.

While climate change is a factor, this is erosion. It was formed by geology and is altered by it. Take away the high seas, in time the Azure Window would still collapse. The famous Arches of Utah are still today being formed anew as others are being slowly eroded.

(12,232 posts)It's a manmade structure now, but for a time it was natural rock. A massive landslide dammed the river for a time, then eroded to become a bridge across the river. It collapsed, possible due to the enormous earthquake in the 1700s.
Rock, water and earth movement creating, then changing.

(2,959 posts)northern CA we've got a beautiful arch at Goat Rock Beach in Sonoma County. I've been knocked down and dragged out to sea by sleeper waves twice at that beach. I rarely turn my back to the ocean on beaches. Imagine what kind of erosion normal waves are doing out there.
here's a video of some kayakers going through that arch.
