Eleven moderate tremors jolted mountainous regions of central Italy on Friday with epicentres in the province of L'Aquila in the Abruzzo region, the national geophysics and vulcanology institute reported.
The quakes struck in the early hours of Friday and the strongest magnitude 3.4 temblor was registered at 3.42 am, the institute said.
The towns closest to the epicentre of the quakes were Pizzoli, Barete and Capitignano, according to the institute.
Two stronger tremors of magnitude 4.0 and 4.1 rocked the province of Macerata in the Marche region late on Thursday at 23.16 and 23.19 respectively, with epicentres near the town of Visso.
Five strong earthquakes have hit central Italy's mountainous spine since last August. The quakes have killed 300 people, left several thousand homeless and caused more than 23 billion euros of damage to homes and other buildings including medieval churches as well as to agriculture.
The quake zone has been hit by thousands of aftershocks over the past eight months.
