Nice video on the geology of Italy. Basically, the spine of Italy was once a giant pressure ridge, caused by compression. Then the stress reversed, and the spine was pulled. This causes the mountain range to be unstable, and it is collapsing on itself.
There is also an aerial view of the damage. It's difficult to get a sense of the percentage of building stock damaged, but I assume it's high.
