Warpy's JournalEarthquake strikes central Italy
A magnitude 6.2 earthquake has struck central Italy, with reports saying some buildings had collapsed.
The quake hit at 03:36 (01:36 GMT), 76 km (47 miles) southeast of the city of Perugia, at the very shallow depth of 10km (six miles), the USGS said.
There were no immediate reports of casualties.
However the USGS predicted these could be significant, based on data from previous quakes.

Simulated black hole experiment backs Hawking prediction
Prof Jeff Steinhauer simulated a black hole in a super-cooled state of matter called a Bose-Einstein condensate.
In the journal Nature Physics, he describes having observed the equivalent of a phenomenon called Hawking radiation - predicted to be released by black holes
"Classical" physics dictates that the gravity of a black holes is so strong that nothing, not even light, can escape. So Hawking's idea relies on quantum mechanics - the realm of physics which takes hold at very small scales.
These quantum effects allow black holes to radiate particles in a process which, over vast stretches of time, would ultimately cause the black hole to evaporate.
