More than 1,000 people were evacuated from the Sicilian town of Niscemi after a four-kilometre section of cliff crumbled following heavy rain brought by Storm Harry.
Land was continuing to give way due to rain that has soaked the area in recent days, said the mayor of the southern hill town of Niscemi.
Footage taken on Monday by the Local Team video agency showed a narrow vertical section of cliff falling away, causing a building that had already been ripped apart to further collapse.
Schools were closed on Monday, and geological surveys have been underway since Sunday evening.
The region's president, Renato Schifani, estimated the cost of the damage, including that from the Niscemi landslide, at more than 1.5 billion euros.
