Shocking video has emerged showing the moment an Italian marina is destroyed by a giant wave from a cruise ship.

The Carnival Vista was approaching the Marina del Nettuno port in Sicily sideways, moving closer and closer to the marina as those on board watched on in horror.

When the ship finally managed to pull away, the force of the propellers created a massive surge, wiping out everything in its path. 

A video posted to shows how the incident unfolded from the perspective of terrified passengers on the ship.

The port authority has launched an investigation into the August 28 incident, which left millions of dollars' worth of damage.
