The southern Italian city of Naples and the surrounding area were shaken by an earthquake at midday on Monday.
The Italian Institute of Geophysics and Volcanology (INGV) said the tremor reached a magnitude of 4.6 - one of the strongest in the region in recent years.
The city's fire brigade said no injuries or major damage have been reported so far.
The Italian news agency ANSA reported that people in western Naples and surrounding communities ran into the streets out of fear of being trapped in collapsed buildings.
The INGV said that the tremor was strongest in Bacoli, a municipality with 26,000 inhabitants about 20 kilometres west of the city of Naples.
The community is in the Phlegraean Fields, an area of high volcanic activity on Europe's largest active "supervolcano."
The region - which also includes the island of Capri - is a popular tourist destination.
