A magnitude 4.8 earthquake occurred in central Italy on Saturday night, shaking apartment buildings in Rome.
The Geophysics Institute the epicentre was Frosinone, between the capital and Naples, at a depth of almost 11km, at 10.16pm.
No injuries or damage were reported.
The tremors sparked calls to emergency services in the Abruzzo region.
The medieval town of L'Aquila was hit in 2009 by a magnitude 6.3 quake that killed more than 300 people. Ruined buildings still mar the landscape.
Earlier on Saturday, three builders and a technician were found guilty of multiple manslaughter after a dormitory they had restored and approved, collapsed during the L'Aquila quake, killing eight students.
The three who carried out building works were sentenced to four years in prison, while the other man received a sentence of 2½ years.
The judge ordered them to pay 100,000 euros to each parent who lost a child and 50,000 euros to each brother or sister.
All four were banned from working on public contracts for five years.
The BBC reports six other defendants were either acquitted or had their charges dropped.
In October last year, six scientists and an official were found guilty of failing to predict the severity of the quake.
