Aerial footage from Italy earthquake zone

The extent of the damage was starting to emerge on Thursday after two earthquakes struck central Italy, the same region hit by a deadly quake in August.

The first tremor struck at 7:10 p.m. (local time, 1710 GMT) on Wednesday and carried a magnitude of 5.4 on the Richter scale.

But the second one a little more than two hours later was eight times stronger at 6.1, according to the US Geological Survey.
