An earthquake measuring 7.1 magnitude struck in central Italy on Sunday, the US Geological Survey said. There were no immediate reports of damage or casualties.
The USGS said the quake was centered 68 km (42 miles) east southeast of Perugia. It was 108 km (67) deep.
An earthquake of magnitude 6.4 struck east of the city on Wednesday, the second of the evening whose tremors were felt as far away as the capital Rome.
The quakes came two months after almost 300 people were killed in the region by a quake that levelled several small towns.
