Italy’s most powerful earthquake since 1980 has left more than 15,000 people homeless, according to the country’s civil protection agency.
No-one was killed in the quake but 20 were injured and damage to the area round the town of Norcia is extensive.
The 6.6-magnitude quake struck near the central region where nearly 300 people were killed by a quake in August.
Prime Minister Matteo Renzi is due to chair a meeting of his cabinet to discuss emergency reconstruction.
The quake struck on Sunday morning, destroying buildings or leaving them structurally unsafe in several towns and villages in the mountainous central region.
Hotels on the Adriatic coast are sheltering some 4,000.
More than 100 aftershocks were registered overnight into Monday, including one of magnitude 4.2.
Tremors from the latest earthquake were felt in the capital Rome, more than 100km (60 miles) away from the epicentre at Norcia.
The Rome metro system was closed on Sunday; an early 20th Century bridge, Ponte Mazzini, has been shut to traffic after cracks appeared; and a crack was visible on the facade of St Paul’s Basilica.
