For statistic purposes, the Istituto Nazionale di Statistica (ISTAT) uses the term Northwest Italy and Northeast Italy for identifying two of the five statistical regions in its reporting.

Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the FrenchItalian border, and at is the highest mountain in the Alps.
