Thousands of people in central Italy are
spending the night in cars, tents and temporary accommodation following
the fourth earthquake in the area in three months.
The 6.6-magnitude quake - Italy's
strongest in decades - struck close to the region where nearly 300
people were killed by a quake in August.
This time no-one appears to have died, but about 20 people were injured.
Powerful aftershocks are still bringing down masonry.
In the town of Norcia, in Perugia
region, close to the epicentre of Sunday morning's earthquake, some
locals have decided to stay in their homes.
Others will spend the night in tents
pitched near the town or are taking up the authorities' offer of shelter
on the Adriatic Coast.
"It will be a difficult night," the head
of Italian Civil Defence, Fabrizio Curcio. "A 6.5 earthquake has
clearly changed the situation."
Norcia resident Stefano Boldrini, who is
now living in a van with his eight-year-old daughter, was asked if they
planned to stay in the area.
"No, how could we? There's no more school, or church, or police station. There's nothing here any more," he said.
The medieval basilica of St Benedict in Norcia was among many historic buildings and structures that were destroyed.
An evacuation of buildings in central
Italy deemed vulnerable to seismic activity last week, following strong
aftershocks from August's quake, may have saved lives.
Officials said three people were dug out of the rubble alive in the town of Tolentino.
Giuseppe Pezzanesi, mayor of Tolentino, said the small town had "suffered our blackest day yet.
"The damage is irreparable. There are
thousands of people in the streets, terrified, crying. Let's hope that
is an end to it, the people are on their knees psychologically."
The towns of Castelsantangelo and Preci
have also suffered considerable damage, but were mainly abandoned after
last week's quakes, of magnitude 5.5 and 6.1.
Castelsantangelo's mayor, quoted by La
Stampa newspaper, said there were no casualties at all in the town as
"everyone had already left".
The mayors of the villages of Ussita and Arquata reported that many buildings had collapsed there too.
Tremors from this latest earthquake were
felt in the capital Rome, where the Metro system was shut down, and as
far away as Venice in the north.
Why multiple quakes are hitting Italy - by Jonathan Amos, BBC science correspondent
We have now seen three magnitude-6 tremors in Italy's Apennines region in just three months.
The big picture is reasonably well
understood. Wider tectonic forces in the Earth's crust have led to the
Apennines being pulled apart at a rate of roughly 3mm per year - about a
10th of the speed at which your fingernails grow.
But this stress is then spread across a
multitude of different faults that cut through the mountains. And this
network is fiendishly complicated.
It does now look as though August's
event broke two neighbouring faults, starting on one known as the Laga
and then jumping across to one called the Vettore.
The mid-week tremors appear to have
further broken the northern end of the Vettore. But both in August and
mid-week, it seems only the top portions of the faults have gone, and
the big question is whether the deeper segments have now failed in the
latest event.
