Claim by claim

The source study was found, but the study's evidence could not be profiled, so these claims couldn't be checked.

Claim 1 of 4Not checkedGeologists led by Stefano Tavani of the University of Florence think Earth's crust is 'unzipping' under Italy, in a process known as delamination.View evidenceHide evidence

As statedunder Italy

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 2 of 4Not checkedThe researchers argue that beneath the Apennines, delamination is happening along a single moving front, or hinge, that is slowly migrating toward the Adriatic foreland.View evidenceHide evidence

As stateda single front ... slowly migrating

Claim 3 of 4Not checkedThe article says the Apennines show contradictory deformation, with around 4 millimeters per year of extension across the mountain belt and about 2 millimeters per year of contraction toward the outer edge.View evidenceHide evidence
