Authorities evacuated 39 families near the Italian city of Naples and schools were closed on Tuesday after a wave of tremors of a strength not seen for decades sparked panic but no injuries.
One 4.4-magnitude quake was registered shortly after 8:00 pm (1800 GMT) on Monday evening at a depth of 2.5 kilometers (1.6 miles), according to the National Institute of Geophysics and Volcanology (INGV).
