Quote:There are a multitude of different faults that cut through the Apennines mountains but the key players over recent months have been two neighbouring faults called the Laga and Vetorre faults.
August's big Magnitude 6.2 jolt, which killed 299 people, occurred on the northern end of the Laga, and ruptured the crust further north still, on to the Vetorre fault.
Then came October with a swathe of quakes that broke much of the rest of the Vetorre. But the stress, according to the seismologists, wasn't just sent north, it was loaded south as well - south of August's event.
And it's in this zone that we have now seen a series of quakes in the past day or so. About a dozen Magnitude fours and fives.
